All Wheel Drive Module (AWD)

U0415-IMPLAUSIBLE DATA RECEIVED FROM ABS

For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams

Theory of Operation

The messages sent on the CAN bus are distinguished by an identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Transmission Control Module (TCM) verifies that it has received the proper number of bytes for each ID.

- When Monitored:
Continuously with the ignition on, one valid CAN ID received at least once, and no U0002-CAN Bus Off Performance DTC present.

- Set Condition:
When the TCM detects an incorrect CAN ID from the ABS control module.





1. CHECK FOR TIPM CAN BUS DTCS
1. With the scan tool, read TIPM DTCs.

Are there any TIPM CAN BUS DTCs present?

Yes

- Testing and Inspection and perform the appropriate test.
- Perform AWD Control Module VERIFICATION TEST. AWD Control Module Verification Test.

No

- Go To 2

2. CHECK IF ABS DTCS ARE PRESENT
1. With the scan tool, read ABS DTCs.

Are there any ABS DTCs present?

Yes

- Testing and Inspection and perform the appropriate test.
- Perform AWD Control Module VERIFICATION TEST. AWD Control Module Verification Test.

No

- Using the schematics as a guide, check the AWD Control Module pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the PCM/TCM.
- Perform AWD Control Module VERIFICATION TEST. AWD Control Module Verification Test.
