P1519-CRUISE CONTROL FRONT DISTANCE SENSOR LENS CRACKED MISSING

For a complete wiring diagram Refer to Diagrams/Electrical.

- When Monitored:

Continuously monitored with the ignition in run, and the ACC Module in normal mode.
- Set Condition:

ACC Module detects the lens damaged or missing. The ACC module will disable the Adaptive Cruise Control (ACC) system and the SERVICE ACC message will display in the CCN. Once the DTC goes to stored, the ACC system will return to normal operation. The DTC will be cleared after the ACC Module sees 100 consecutive key cycles of the STORED DTC.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

1.DTC IS ACTIVE

NOTE: To help in the service of the Adaptive Cruise Control (ACC) System, it is recommended speaking to the customer to find out what type of environment they were driving in when the cruise concern took place. Heavy rain, snow, ice and fog can cause the ACC system to become unavailable. This should be considered normal operation and no repair is necessary.

NOTE: Vehicles that have had the suspension modified and/or a aftermarket grill installed that blocks the ACC sensor can cause the Adaptive Cruise Control (ACC) system not to operate properly.

With a scan tool, select View DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- No repair is necessary. Ensure the lens is free of dirt, damage or other obstruction. Clear the DTC and verify the proper operation of the ACC system.

2.ACC SENSOR LENS

NOTE: Ensure the ACC Sensor lens is free from dirt and/or any debris (mud, dirt, ice, road debris) that would compromise the function of the ACC system.

Perform a thorough visual and physical inspect of the ACC Module, look for a missing sensor lens or a damaged lens.

Is the lens damaged or missing?

Yes

- Replace the ACC Module.
- Perform the ACC MODULE VERIFICATION TEST. Adaptive Cruise Control (ACC) Verification Test

No

- Check the ACC Module harness connector terminals for corrosion, damage, or terminal push out. Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits. Repair as necessary. If the connector and wiring are found to be OK, replace the ACC Module.
