DESCRIPTION AND OPERATION
Parking Aid
Component Location
- Parking aid speaker
- PAM
- Parking aid sensors
Overview
The parking aid system sounds a warning to alert the driver of stationary objects near the rear bumper when REVERSE is selected. The rear sensors are activated when REVERSE is selected. The parking aid system assists the driver in detecting certain objects while the vehicle moves slowly in REVERSE at speeds of less than 4.8 kmh (3 mph). The parking aid system may not detect moving objects.
The parking aid system is active when the ignition switch is in the RUN position and the transmission in REVERSE. The parking aid system is disabled if a fault is detected in 1 of the 4 sensors, the parking aid speaker, or the PAM. This is indicated by a parking aid disabled warning message in the message center.
The parking aid system is enabled and disabled through the message center, located in the IPC.
If a MyKey restricted key is in use, the parking aid menu is not available in the message center and cannot be deactivated.

Parking Aid System Operation
The parking aid system calculates the distance to an object around the rear of the vehicle using 4 ultrasonic sensors. The parking aid sensors detect objects approximately 1,524 mm (60 in) from the rear of the vehicle, 508 mm (20 in) from the rear side of the vehicle, and 304.8 mm (12 in) above the ground.
The PAM calculates the distance to an object within the 170 degree semicircular (azimuth) area around the rear of the vehicle. A variable-rate warning tone is generated from a speaker attached to the PAM.
The PAM can be diagnosed with a scan tool.
Parking Aid Audible Alert
The speaker increases its warning tone rate as the vehicle gets closer to an obstacle. When an object is detected within 304.8 mm (12 in) of the sensors, the warning tone becomes continuous.
When the PAM sounds the parking aid tone, it sends an audio volume cutback message to the IPC which sends a message over the to the ACM. When the ACM receives the message, it reduces the speaker output so the parking aid tone can be heard. If the vehicle is equipped with Sony sound the audio DSP module reduces the speaker output.
Component Description
Parking Aid Sensors
The parking aid sensors are 3-wire type ultrasonic distance detecting sensors.
Parking Aid Module (PAM)
The PAM calculates and reports via audible output the distance between the rear of the vehicle and an object. The PAM requires PMI when replaced.
Parking Aid Speaker
The parking aid speaker is a variable-rate warning tone and is commanded by the PAM.

GENERAL PROCEDURES
Azimuth System Check
Minimum Detectable Object Locations
- NOTE: The object used in this system check can be fabricated
using a 9 cm diameter (3 in I.D.) pipe, 100 cm (39 in) in length (available
as Polyvinyl Chloride (PVC) pipe, or similar from a hardware or plumbing
supply.
NOTE: The following system check should be carried out with the vehicle on a level surface.
NOTE: The parking aid system defaults to on when the ignition key is cycled from the OFF position to the ON position.
Turn the ignition switch to the ON position, engine off.
- Apply the parking brake.
- Place the gear shift in REVERSE (R).
- Verify that the Parking Aid Module (PAM) detects the objects when placed
in the 5 specified locations (P1, P2, P3, P4 and P5).
- The speaker should beep slowly when objects are detected on the outer edges of the detection zone, and increase as the object is moved closer to the vehicle. When the object is within 25 cm (10 in) of the rear bumper, the sounder should sound continuously.
- If the PAM does not detect the object above, refer to Parking Aid in the Diagnosis and Testing portion of this section.
Elevation System Check
- Check the parking aid system to make sure the system does not see signals caused by ground reflections.
- The following system check should be carried out with the vehicle on a 4.6 m (15 ft) wide by 3.0 m (10 ft) deep smooth concrete surface, free of all obstacles. The area should also be free of noise from fans and pneumatic tools.
- Turn the ignition switch to the ON position, engine off.
- Apply the parking brake.
- Place the gear shift in REVERSE (R).
- NOTE: No audible warning tones should be heard. If audible
warning tones are heard, check to make sure the bumper is installed
correctly and not tilted downward so that the sensor is pointing towards the
ground.
Verify that no audible warning tones are heard.
- If the audible warning tone is heard, refer to Parking Aid in the Diagnosis and Testing portion of this section.
