Ford Taurus. Steering System

DESCRIPTION AND OPERATION

Steering Column

The steering column system consists of the following components:

  • Intermediate shaft
  • Steering column
  • SCCM (if equipped)
  • Steering column switches
  • Steering column tilt motor (if equipped)
  • Steering wheel
  • Selector lever (if equipped)
  • Upper and lower steering column shrouds

The steering column is the mechanical linkage between the steering wheel and the steering gear. The steering wheel is mounted to a shaft which passes through the center of the steering column. The shaft is centered by bearings within the steering column. The steering column shaft then connects the steering column to the steering gear. The upper and lower steering column shaft connections utilize U-joint type couplings.

Manual Adjustable Tilt/Telescope Steering Column (If Equipped)

The manual tilt/telescope function of the steering column is controlled by a mechanical lever on the underside of the steering column, which uses a cam to lock and unlock the steering column. When the lever is pulled down, the steering column can be adjusted up or down and in or out to the desired position(s). While holding the steering wheel in the desired position, pulling the lever up to its original position locks the steering column.

Power Adjustable Tilt/Telescope Steering Column (If Equipped)

The steering column is the mechanical linkage between the steering wheel and the steering gear. The steering wheel is mounted to a steering column shaft which passes through the center of the steering column. The steering column shaft is centered by bearings within the steering column. The steering column shaft utilizes U-joint type couplings in order to connect the steering column to the steering gear.

The power tilt and telescope function of the steering column is controlled by the steering column control switch, the memory SET switch or the RKE transmitter. The steering column control switch is a normally open 4-position momentary switch, located below the multifunction switch. When the steering column control switch is pressed, the steering column tilt motor moves the adjustable steering column in 4 directions:

  • Forward/in (away from the driver)
  • Rearward/out (toward the driver)
  • Up
  • Down

For steering column switch service information, refer to Section 211-05.

For selector lever service information, refer to Section 307-05.

Heated Steering Wheel

The heated steering wheel system consists of the following components:

  • Heated steering wheel (with integral heating elements and temperature sensor)
  • HSWM
  • Heated steering wheel buttons and indicators.

The buttons and indicators for the heated steering wheel system are located in the FDIM (touchscreen) only. When activated, the HSWM activates the steering wheel heater elements, which heats the steering wheel and maintains a temperature of approximately 28-34ºC (82-94ºF) until switched off on the FDIM or the ignition is turned OFF.

The heated steering wheel can be set to activate (configured through the IPC ) when the vehicle is remotely started. During a remote start event, heated steering wheel activation depends on the ambient temperature of the vehicle and climate strategy of the HVAC module.

DIAGNOSIS AND TESTING

Steering Column

Principles of Operation

Power Adjustable Tilt/Telescope Steering Column

The power adjustable tilt/telescope steering column is controlled by the steering column control switch and 2 electric motors that are powered by the SCCM. The steering column control switch is mounted directly to the SCCM on the LH side of the steering column just below the multifunction switch, but is serviceable separately. The steering column control switch is a 4-position, momentary contact switch. When the steering column control switch is moved to any of the 4 positions, it sends a signal to the SCCM to tilt the steering column up or down or telescope the steering column forward or rearward.

The SCCM continuously monitors the steering column tilt and telescoping motors and circuits for faults. If a fault is detected, the SCCM is capable of setting DTCs.

Tilt/Telescoping Motor Sensors

The SCCM receives digital signals from Hall-effect type rotation sensors that are integral to the tilt and telescoping motors. The SCCM uses these signals to calculate the location of the steering column in relation to the full forward/rearward and full up/down positions. The SCCM also uses these signals to store and recall memory positions, carry out the easy entry/exit operations and to make sure the tilt and telescoping motors do not stall against the steering column end of travel in the forward/rearward or up/down directions. The tilt motor is serviced separately from the steering column. The telescoping motor is not serviceable. If a new telescoping motor is needed, a new steering column must be installed.

Jog Mode

If the SCCM loses the signal from either of the motor sensors, the affected steering column motor operates in jog mode. Jog mode allows limited operation of the affected steering column motor using only the steering column control switch. When the steering column control switch is operated in jog mode, the steering column moves in the desired direction for one second, then stops. The steering column control switch must be released, then pressed again in order to move the steering column for an additional second. Jog mode is an indication that there is a tilt or telescoping motor sensor fault. If the adjustable steering column is operating in jog mode, a DTC may set in the SCCM.

Memory Position Programming and Recall

The SCCM monitors steering column position using Hall-effect sensors that are integral to the tilt and telescoping motors. When a memory position is recalled through either the memory SET switch or the RKE transmitter, the SCCM monitors the Hall-effect sensors and stops sending voltage to the steering column motors once the commanded memory position is reached. If the SCCM receives a steering column switch input during a memory position recall function, the module stops the memory recall and responds to the new steering column switch position input.

When the RKE transmitter is activated, a message is sent over the MS-CAN to the DSM. When the memory SET switch is pressed, the DSM senses continuity to ground on the switch circuit. When the DSM receives either the MS-CAN message or the ground input through the switch circuit, it sends a message over the MS-CAN to the BCM. The BCM acts as a gateway module, relaying the MS-CAN message that was received from the DSM to the SCCM over the High Speed Controller Area Network (HS-CAN). The SCCM then sends voltage over the appropriate circuit to the steering column tilt or telescoping motor to adjust the steering column position.

For additional information on setting and recalling a memory position, refer to the Owner's Literature or Memory Position Programming in Section 501-10.

Easy Entry/Exit

The easy entry/exit function moves the steering column to the full inward and upward position when the selector lever is in the PARK position and the ignition is selected off (if equipped with a push button start system) or if the ignition switch indicates the ignition key has been removed from the ignition lock cylinder (if equipped with an ignition switch). The SCCM receives an ignition status message over the HS-CAN. When the ignition status message indicates the ignition key has been removed from the lock cylinder (vehicles with an ignition switch), the SCCM commands the steering column to the full upward/forward position. For vehicles equipped with a push button start system, this occurs when the ignition status message indicates the ignition has transitioned to off. The SCCM cancels this operation if a valid input is received from the steering column control switch or memory position switch.

The SCCM records the current steering column position before powering the steering column for an easy exit operation. This recorded position returns the steering column to this position on the next easy entry operation. During easy entry operation, the steering column is returned to the position previous to the easy exit operation.

The easy entry/exit feature can be activated or deactivated using the message center. Refer to driver controls in the Owner's Literature for additional instructions for using the message center.

Pinpoint Test B: The Adjustable Steering Column is Inoperative in One or More Directions - Using the Memory SET Switch Buttons/Using an RKE Transmitter/Using the Easy Entry/Exit Feature

Refer to Wiring Diagrams Cell 128, Adjustable Steering Column for schematic and connector information.

Normal Operation

When the desired memory position is selected using the memory SET switch or an RKE transmitter, the DSM communicates the desired steering column position in a message on the MS-CAN to the BCM. The BCM acts as a gateway module, relaying the message to the SCCM over the HS-CAN. The SCCM monitors the position of the adjustable steering column using Hall-effect type rotation sensors that are integral to the tilt and telescoping motors. The sensors provide a digital signal used by the SCCM to calculate the position of the steering column in relation to the full forward/rearward and full up/down positions. The SCCM uses these signals to store and recall memory positions, carry out easy entry/exit operations and to make sure the tilt and telescope motors do not stall against the steering column end of travel. If a tilt or telescope motor sensor DTC sets, the SCCM does not recall a programmed memory position or automatically position the steering column during the easy entry/exit operation. If a DTC sets for either sensor, the affected adjustable steering column motor operates in jog mode. Jog mode allows limited operation of the affected steering column motor using only the steering column control switch. When the steering column control switch is operated in jog mode, the steering column moves in the desired direction for one second, then stops. The steering column control switch must be released, then pressed again in order to move the steering column for an additional second.

Pinpoint Test C: The Adjustable Steering Column Operates in One Second Intervals When Using the Steering Column Control Switch (Jog Mode)

Refer to Wiring Diagrams Cell 128, Adjustable Steering Column for schematic and connector information.

Normal Operation

The SCCM monitors the position of the adjustable steering column using of Hall-effect type rotation sensors that are integral to the tilt and telescoping motors. The adjustable steering column tilt motor is serviced separately from the steering column. The adjustable steering column telescope motor is not serviceable. If a new adjustable steering column telescope motor sensor is needed, install a new steering column assembly.

The SCCM sends a reference voltage along the sensor feed circuit through the Hall-effect sensor and back to the SCCM through a shared signal return circuit. The sensors provide a digital signal used by the SCCM to calculate the position of the steering column in relation to the full forward/rearward and full up/down positions. The SCCM uses this signal to store and recall memory positions, to carry out the easy entry/exit operations and to make sure the adjustable steering column tilt and telescope motors do not stall against the steering column end of travel.

If an adjustable steering column tilt or telescope motor sensor DTC sets (or if either of the sensor circuits become open), the SCCM does not recall a programmed memory position or automatically position the steering column during the easy entry/exit operations. The affected steering column motor operates in jog mode. Jog mode allows limited operation of the affected steering column motor using only the steering column control switch. When the steering column control switch is operated in jog mode, the steering column moves in the desired direction for one second, then stops regardless of the length of time the switch is actually activated. The steering column control switch must be released, then activated again in order to move the steering column for an additional second.

Heated Steering Wheel

Principles of Operation

Heated Steering Wheel System Operation

When a heated steering wheel request is received, the HSWM applies voltage and ground to the steering wheel heating element (integral to the steering wheel). The steering wheel is heated to a temperature of approximately 28-34ºC (82-94ºF) and is maintained by the HSWM using a temperature sensor (integral to the steering wheel). The HSWM supplies a reference voltage and ground to the temperature sensor and monitors the voltage drop for controlling current flow to the heating element. The HSWM is designed to remain on, heating the steering wheel and maintaining temperature until switched OFF on the FDIM or the ignition switch is turned OFF.

On all vehicles, slow heating between the 10 o'clock and 2 o'clock steering wheel hand positions is considered normal. On vehicles equipped with wood inserts in the steering wheel, there is no heating elements located under the inserts.

Heated Steering Wheel System Network Communication

The controls and indicators for the heated steering wheel system are in are located in the FDIM (touch screen) only. The FDIM does not communicate on any network and is connected directly to the APIM.

When the FDIM controls are used, the APIM sends a heated steering wheel request message to the HSWM using the following message path:

  • The APIM sends the request over the I-CAN to the FCIM.
  • The FCIM sends the request over the I-CAN to the IPC module.
  • The IPC module then sends the request to the BCM over the HS-CAN.
  • Lastly, the BCM sends the requests to the HSWM over the MS-CAN.

The messaging path is followed in reverse for status updates that need to be sent from the HSWM to the APIM.

Remote Start System Behavior

When the remote start feature is used, the heated steering wheel system may be configured, through the message center, to be activated by the HVAC module based on outside air temperature. During remote start, the outside air temperature is continually evaluated by the HVAC system and the heated steering wheel system activation changes if the outside air changes from cold to moderate or warm temperatures or back from moderate or warm to cold temperatures.

For cold ambient air temperatures (below 10ºC (50ºF) ) the heated steering wheel activates if the steering wheel is set to Auto in the IPC message center.

For moderate and warm ambient air temperatures (above 10ºC (50ºF) ) the heated steering wheel does not activate.

FET Protection

A FET is a type of transistor, that used with module software, monitors and controls current flow on module outputs. For information on FET protection, refer to Section 419-10.

Inspection and Verification

  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.

Pinpoint Tests

Pinpoint Test D: DTC B135C:11 or B135C:15

Refer to Wiring Diagrams Cell 128, Adjustable Steering Column for schematic and connector information.

Normal Operation

When steering wheel heat is requested, the HSWM applies voltage and ground to the steering wheel heating element (integral to the steering wheel). The steering wheel heating element will draw between 1 and 10A of current depending on steering wheel temperature. The steering wheel contains 3 heating elements wired in parallel and has a resistance of 1.6-2.6 ohms. If the steering wheel is equipped with wood inserts, the steering wheel contains 2 heating elements wired in parallel and has a resistance of 2.1-3.1 ohms. The heated steering wheel temperature is maintained by the HSWM using a sensor in the steering wheel (integral to the steering wheel). The HSWM is designed to remain on, heating the steering wheel and maintaining temperature until switched OFF on the FDIM or the ignition is turned OFF.

  • DTC B135C:11 (Heater Element: Circuit Short to Ground) - This DTC will only set when the heated steering wheel is commanded on. The module senses current greater than 10A on the steering wheel heating element output circuit for greater than 80ms, indicating a short to ground, this DTC sets. This DTC also sets when the steering wheel heating element output FET in the module has a thermal failure. The steering wheel heating element output will be disabled until the ignition is cycled.
  • DTC B135C:15 (Heater Element: Circuit Short to Battery or Open) - This DTC will only set when the heated steering wheel is commanded on. The module senses current less than 1A on the steering wheel heating element output circuit for more than 80ms, indicating a short to voltage or an open circuit or heating element. The steering wheel heating element output will be disabled until the ignition is cycled.
