Pinpoint Test H: Visual Park Aid Is Inoperative

Refer to Wiring Diagram Set 131, Parking Aid for schematic and connector information. Diagrams By Number

Normal Operation

When the transmission selector is in REVERSE (R) and an object is detected in the path of the parking aid sensor, a network message of the distance from the parking aid sensor to the object is sent from the Parking Aid Module (PAM) to the Body Control Module (BCM) over the High Speed Controller Area Network (HS-CAN). The BCM networks the parking aid sensor message to the video camera over the Local Interconnect Network (LIN). The visual alerts are red, yellow or green and appear as highlights on top of the displayed image to indicate in which zone the object is detected. The visual park aid feature can be enabled and disabled within the Front Display Interface Module (FDIM).

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Video camera
- PAM
- BCM

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

-------------------------------------------------
H1 VERIFY THE VISUAL PARK AID IS ENABLED

- For vehicles with navigation, verify that the visual park aid is enabled in the FDIM.
- For vehicles without navigation, verify that the visual park aid is enabled in the message display.
- Is the visual park aid enabled in the FDIM or message center display?

Yes
GO to H2.

No
ENABLE the visual park aid. TEST the system for normal operation.

-------------------------------------------------
H2 CHECK THE DTCs FROM THE PAM SELF-TEST

- Check the PAM DTCs from the self-test.
- Are any PAM DTCs recorded?

Yes
REPAIR all PAM DTCs first. REFER to Parking Aid Special Tool(s) Used With Diagnostics. TEST the system for normal operation.

No
GO to H3.

-------------------------------------------------
H3 CHECK THE DTCs FROM THE BCM SELF-TEST

- Check the BCM DTCs from the self-test.
- Are any BCM DTCs recorded?

Yes
REFER to DTC Charts. Parking Aid - Video - DTC Charts

No
GO to H4.

-------------------------------------------------
H4 CHECK FOR CORRECT VIDEO CAMERA OPERATION

- Connect: All Disconnected Connectors.
- Disconnect the video camera connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the video camera connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new video camera. REFER to Video Camera Service and Repair. 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.
