Symptom Chart - NVH

NOTE: NVH symptoms should be identified using the diagnostic tools that are available. For a list of these tools, an explanation of their uses and a glossary of common terms, refer to Section 100-04. Since it is possible any one of multiple systems may be the cause of a symptom, it may be necessary to use a process of elimination type of diagnostic approach to pinpoint the responsible system. If this is not the causal system for the symptom, refer back to Section 100-04 for the next likely system and continue diagnosis.

Pinpoint Tests

Pinpoint Test A: Both Non-Memory Mirrors Are Inoperative

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 124, Power Mirrors for schematic and connector information.

Normal Operation and Fault Conditions

The accessory delay relay is located inside the BCM and supplies voltage to the master window control switch when the BCM energizes the relay by grounding the relay coil. The exterior mirror control switch is integral to the master window control switch and receives power whenever the master window control switch is powered by the accessory delay relay. The exterior mirror control switch has only one ground circuit. The exterior mirrors share a common circuit for both up/down and right/left movement.

Possible Sources

  • Fuse
  • Wiring, terminals or connectors
  • Exterior mirror control switch (integral to the master window control switch)

PINPOINT TEST A: BOTH NON-MEMORY MIRRORS ARE INOPERATIVE

Pinpoint Test B: One Non-Memory Mirror Is Inoperative

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 124, Power Mirrors for schematic and connector information.

Normal Operation and Fault Conditions

Each exterior mirror motor has specific circuits that control the down/up and left/right movement of the glass. The motors share a common return circuit.

Possible Sources

  • Wiring, terminals or connectors
  • Exterior mirror control switch (integral to the master window control switch)
  • Exterior mirror motor
  • Exterior mirror

Pinpoint Test E: The Memory Mirror is Inoperative

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 124, Power Mirrors for schematic and connector information.

Normal Operation and Fault Conditions

The exterior mirror control switch sends voltage and ground inputs to the Driver Door Module (DDM) which controls LH mirror movement by providing the appropriate voltage and ground polarity to the LH exterior mirror up/down and left/right motors. The Driver Seat Module (DSM) controls RH mirror movement by providing the appropriate voltage and ground polarity to the RH exterior mirror up/down and left/right motors. The LH and RH exterior mirrors each contain potentiometers for up/down and left/right position status. The DDM (LH mirror) and DSM (RH mirror) supply the exterior mirror feedback potentiometers a reference voltage and reference ground. The DDM and DSM use these feedback signals to store/recall mirror positions.
