Refer to Wiring Diagram Set 42, Vehicle Dynamic Systems for schematic and connector information. Diagrams By Number
Normal Operation
When the ignition is turned to the RUN position, the ABS module and the PCM share Vehicle Identification Number (VIN) information over the High Speed Controller Area Network (HS-CAN).
- DTC U3002:62 (Vehicle Identification Number: Signal Compare Failure) - sets in continuous memory and indicates that the VIN message sent by the PCM over the HS-CAN does not match the VIN stored in the ABS module.
This pinpoint test is intended to diagnose the following:
- Module configuration (ABS module and PCM)
- ABS module
PINPOINT TEST N: DTC U3002:62
-------------------------------------------------
N1 VERIFY PCM VIN

- Enter the following diagnostic mode on the scan tool: Log Viewer.
- Compare the VIN in Log Viewer to the vehicle VIN plate.
- Does VIN in Log Viewer match the vehicle VIN plate?
Yes
GO to N2.
No
CARRY OUT Programmable Module Installation (PMI) for the PCM. REFER to Module Configuration Programmable Module Installation (PMI), using the Integrated Diagnostic System (IDS) when the original module is NOT available. TEST the system for normal operation.

N2 VERIFY ABS MODULE PART NUMBER
- Retrieve and record the ABS module part number from Log Viewer and verify that the vehicle has the correct ABS module installed.
- Is the correct ABS module installed in the vehicle?
Yes
CARRY OUT PMI for the ABS module. REFER to Module Configuration Programmable Module Installation (PMI), using the IDS when the original module is NOT available. TEST the system for normal operation.
