Pinpoint Test AI: The CHECK PARK ASSIST/PARK ASSIST OFF Warning Is Inoperative

Normal Operation

The parking aid on/off status is sent from the Parking Aid Module (PAM) to the Instrument Cluster (IC) over the Medium Speed Controller Area Network (MS-CAN) communication bus lines. When the RESET button is pressed, the IC sends a query to the PAM, requesting a system status. The PAM responds to the IC with the status of the system, either on or off. If the return status message is missing or corrupt, the IC does not display the brackets around either the ON or OFF selection.

This pinpoint test is intended to diagnose the following:

- Parking aid system concern
- Communication network



PINPOINT TEST AI: THE CHECK PARK ASSIST/PARK ASSIST OFF WARNING IS INOPERATIVE

-------------------------------------------------
AI1 CHECK THE PARKING AID SYSTEM OPERATION


- Operate the parking aid system and check for correct operation when the feature is selected on and off. Refer to the Owner's Literature for additional information on selecting the parking aid system on or off.
- Does the parking aid system operate correctly when the feature is selected on then off?

Yes
GO to AI2.

No
REFER to Collision Avoidance and Parking Assist Systems.

-------------------------------------------------
AI2 CHECK THE MESSAGE CENTER ON/OFF DISPLAY


- Press the SETUP button until PARKING ASSIST ON OFF is displayed.
- Does the ON or OFF have the [ ] brackets around it indicating the desired selection?

Yes
If the brackets remain, the system is operating normally at this time. The problem may have been caused by a momentary loss of communication with the PAM.

No
PRESS the RESET button to allow the IC to query the PAM again.

If the display is still incorrect, REFER to Information Bus to diagnose no communication with the PAM.
