Adaptive Cruise Control Module (ACC)

U0415-00-IMPLAUSIBLE DATA RECEIVED FROM ABS

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:

Continuously monitored with the engine running and the Adaptive Cruise Control (ACC) Module in normal mode.

- Set Condition:

The ACC Module receives an implausible (default/error value or toggle error or parity error are present) message from the Anti-Lock Brakes Module (ABS) Module for 300 millisecond. The ACC module will disable the ACC system and the ACC UNAVAILABLE message will display in the Cabin Compartment Node (CCN). Once the Diagnostic Trouble Code (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.






For gasoline engines, always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. VERIFY THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE

NOTE: Diagnose all communication failures before continuing.

1. Ignition on, engine not running.
2. Using a scan tool, read ACC DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors, pay particulate attention the CAN circuits.
- Perform ADAPTIVE CRUISE CONTROL VERIFICATION TEST. Adaptive Cruise Control (ACC) Verification Test.

2. VERIFY ABS MODULE IS ACTIVE ON CAN C BUS

1. Using a scan tool, select ECU View.
2. Verify that the ABS Module is active on the bus.

Is the ABS Module active on the bus?

Yes

- Go To 3

No

- Perform the U0121-LOST COMMUNICATION WITH ABS diagnostic procedure. Body Control Module (BCM)

3. CHECK FOR ACTIVE OR STORED DTCs IN ABS MODULE

1. Using a scan tool, read ABS Module DTCs.

Are any DTCs active or stored in the ABS Module?

Yes

- Perform the appropriate diagnostic procedure. Testing and Inspection.

No

- Go To 4

4. CHECK FOR ACTIVE OR STORED COMMUNICATION DTCs IN BCM

1. Using a scan tool, read BCM DTCs.

Are any active of stored ABS Module Communication DTCs set in the BCM?

Yes

- Perform the appropriate diagnostic procedure. Testing and Inspection.

No

- Replace and program the ACC Module.
- Perform ADAPTIVE CRUISE CONTROL VERIFICATION TEST. Adaptive Cruise Control (ACC) Verification Test.
