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 uses a run/start input messaged from the BCM over the High Speed Controller Area Network (HS-CAN).

This pinpoint test is intended to diagnose the following:

- Communication concern
- IPC

PINPOINT TEST A: THE IPC 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 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 passed the network test.
- Did the IPC pass the network test?

Yes
GO to A2.

No
REFER to Module Communications Network Testing and Inspection to diagnose the IPC does not respond to the scan tool.

-------------------------------------------------
A2 RETRIEVE THE RECORDED DTCs FROM THE BCM SELF-TEST

- Check for recorded BCM DTCs from the self-test.
- Are any DTCs recorded?

Yes
REFER to Multifunction Electronic Modules Multifunction Electronic Modules.

No
GO to A3.

-------------------------------------------------
A3 CHECK FOR CORRECT IPC OPERATION

- Disconnect the IPC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IPC 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. REFER to Instrument Panel Cluster (IPC) 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.
