Parking Aid

Pinpoint Test A: The Parking Aid Is Inoperative

Normal Operation

The parking aid system is enabled when the ignition switch is in the RUN position and the reverse gear is selected. The Parking Aid Module (PAM) receives reverse gear input from the PCM through the High Speed Controller Area Network (HS-CAN). A reference voltage and signal return is supplied to the parking aid sensors from the PAM (Parking Aid Module). The PAM (Parking Aid Module) receives an input signal from each individual parking aid sensor. The system can be disabled through the message center in the Instrument Panel Cluster (IPC).

NOTE: If a MyKey(R) restricted key is in the ignition cylinder, the parking aid menu is not available in the message center and cannot be deactivated.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Parking aid sensors alignment

- PAM (Parking Aid Module)

- Rear bumper cover

Does the message center display PARK AID OFF when the parking aid system is disabled, and display PARK AID ON when the parking aid system is enabled?

Yes
GO to A3.

No
REFER to Instrument Panel, Gauges and Warning Indicators.

A3 CHECK FOR CORRECT REVERSE GEAR INPUT

- Apply the parking brake.

- Ignition ON.

- Select REVERSE.

- Enter the following diagnostic mode on the scan tool: PAM (Parking Aid Module) DataLogger.

- Monitor the PAM (Parking Aid Module) transmission range PID (TRANSGR).

Does the PID indicate YES (transmission in reverse)?

Yes
GO to A4.

No
REFER to Automatic Transmission/Transaxle &/or Transmission Control Systems.

A4 CHECK FOR CORRECT PAM (Parking Aid Module) OPERATION

- Ignition OFF.

- Disconnect the PAM (Parking Aid Module) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the PAM (Parking Aid Module) connector and make sure it seats correctly.

- Operate the system and determine if the concern is still present.

Is the concern still present?

Yes
INSTALL a new PAM (Parking Aid Module). REFER to Parking Aid Module (PAM) . TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
