Pinpoint Test K: DTC U3002:62

Anti-Lock Control

Pinpoint Test K: DTC U3002:62

Refer to Wiring Diagram Set 42, Vehicle Dynamic Systems for schematic and connector information Electrical Diagrams.

Normal Operation

When the ignition is turned to the RUN position, the ABS module and the IPC (Instrument Panel Cluster) share Vehicle Identification Number (VIN) information over the High Speed Controller Area Network (HS-CAN) bus. Correct any network communications DTCs prior to diagnosing DTC U3002:62

- DTC U3002:62 (Vehicle Identification Number: Signal Compare Failure)- this DTC sets when the VIN (Vehicle Identification Number) message sent by the IPC (Instrument Panel Cluster) over the HS-CAN (High Speed Controller Area Network) does not match the VIN (Vehicle Identification Number) stored in the ABS module.

This pinpoint test is intended to diagnose the following:

- Module configuration (ABS and IPC (Instrument Panel Cluster))

- ABS module

PINPOINT TEST K : DTC U3002:62

K1 VERIFY IPC (Instrument Panel Cluster) VIN (Vehicle Identification Number)

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Log Viewer.

- Compare the VIN (Vehicle Identification Number) in Log Viewer to the vehicle VIN (Vehicle Identification Number) plate.

Does VIN (Vehicle Identification Number) in Log Viewer match the vehicle VIN (Vehicle Identification Number) plate?

Yes
GO to K2.

No
CARRY OUT Programmable Module Installation (PMI) for the IPC (Instrument Panel Cluster) Programmable Module Installation (PMI). REFER to Information Bus. TEST the system for normal operation.

K2 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 (Programmable Module Installation) for the ABS module Programmable Module Installation (PMI). TEST the system for normal operation.

No
INSTALL a new ABS module. REFER to Hydraulic Control Unit (HCU) Service and Repair. CLEAR the DTC. CYCLE the ignition key. REPEAT the self-test.
