Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

1. Disconnect the following connectors:

•	The instrument panel (IPC) cluster connector

•	The radio connector

•	The multi-function alarm module connector C1

•	The cruise control module connector

•	The powertrain control module (PCM) connector C3

2. Measure the voltage in CKT 817 between the IPC connector terminal B3 (terminal B2 for Pontiac) and ground.

Does the voltage equal the specified value?

0 V
