Diagnostic Routine A

Diagnostic Overview

The Instrument Panel Cluster (IPC) Is Inoperative

Refer to Wiring Diagram Set 60 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

The IPC (Instrument Panel Cluster) receives a hot at all times voltage from the BCM (Body Control Module). The IPC (Instrument Panel Cluster) receives the ignition status message from the BCM (Body Control Module) over the HS-CAN (High Speed Controller Area Network).

Visual Inspection and Diagnostic Pre-checks

Inspect the BCM (Body Control Module) fuse 11 (10A).

Pinpoint Test

1. VERIFY THE IPC (Instrument Panel Cluster) PASSES THE NETWORK TEST

1. Ignition ON.

2. Using a scan tool, perform the network test.

3. Verify whether the IPC (Instrument Panel Cluster) passed the network test.

Did the IPC (Instrument Panel Cluster) pass the network test?








2. CARRY OUT THE IPC (Instrument Panel Cluster) SELF-TEST

1. Using a scan tool, perform the IPC (Instrument Panel Cluster) self-test.

2. Check for recorded DTCs (Diagnostic Trouble Codes) from the IPC (Instrument Panel Cluster) self-test.

Are any DTCs (Diagnostic Trouble Codes) recorded?








3. CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION

1. Disconnect and inspect the IPC (Instrument Panel Cluster) connector.

2. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged or bent pins- install new terminals/pins
- pushed-out pins- install new pins as necessary

3. Reconnect the IPC (Instrument Panel Cluster) connector. Make sure it seats and latches correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?
