Pinpoint Test A: The Instrument Panel Cluster (IPC) Is Inoperative

Normal Operation

The Instrument Panel Cluster (IPC) receives a hot at all times voltage from the Body Control Module (BCM) fuse 11 (10A). The IPC (Instrument Panel Cluster) uses a run/start input messaged from the BCM (Body Control Module) over the High Speed Controller Area Network (HS-CAN).

This pinpoint test is intended to diagnose the following:

- Communication concern

- IPC (Instrument Panel Cluster)

PINPOINT TEST A : THE IPC (Instrument Panel Cluster) IS INOPERATIVE

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

A1 VERIFY THE IPC (Instrument Panel Cluster) PASSES THE NETWORK TEST

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Network Test.

- In the LH pane of the Integrated Diagnostic System (IDS) network test display screen, verify whether the IPC (Instrument Panel Cluster) passed the network test.

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

Yes
GO to A2.
No
REFER to Information Bus to diagnose the IPC (Instrument Panel Cluster) does not respond to the scan tool.

A2 RETRIEVE THE RECORDED DTCs FROM THE BCM (Body Control Module) SELF-TEST

- Check for recorded BCM (Body Control Module) DTCs from the self-test.

Are any DTCs recorded?

Yes
REFER to Body Control Systems.
No
GO to A3.

A3 CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION

- Disconnect the IPC (Instrument Panel Cluster) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the IPC (Instrument Panel Cluster) connector and make sure it seats correctly.

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

Is the concern still present?

Yes
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
