Pinpoint Test I: Visual Park Aid Is Inoperative

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

Normal Operation

When the transaxle selector in the reverse position 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 (Body Control Module) networks the parking aid sensor message over the Local Interconnect Network (LIN) to the video camera. 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 with in the Front Display Interface Module (FDIM).

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Video camera

- PAM (Parking Aid Module)

- BCM (Body Control Module)

PINPOINT TEST I : VISUAL PARK AID IS INOPERATIVE

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

I1 VERIFY THE VISUAL PARK AID IS ENABLED

- Verify that the visual park aid is enabled in the FDIM (Front Display Interface Module).

Is the visual park aid enable in the FDIM (Front Display Interface Module)?

Yes
GO to I2.

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

I2 CHECK THE DTCs FROM THE PAM (Parking Aid Module) SELF-TEST

- Check the PAM (Parking Aid Module) DTCs from the self-test.

Are any PAM (Parking Aid Module) DTCs recorded?

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

No
GO to I3.

I3 CHECK THE DTCs FROM THE BCM (Body Control Module) SELF-TEST

- Check the BCM (Body Control Module) DTCs from the self-test.

Are any BCM (Body Control Module) DTCs recorded?

Yes
REFER to DTC Charts Parking Aid - Video.

No
GO to I4.

I4 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 . 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.
