Pinpoint Test A: The IPC Is Inoperative: Notes
Pinpoint Test A: The Instrument Panel Cluster (IPC) Is Inoperative
Refer to Wiring Diagrams Instrument Panel Cluster for schematic and connector information.
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:
- Fuse
- Wiring, terminals or connectors
- Communication concern
- IPC
