1. Disconnect the following connectors:

•	The instrument panel (IPC) cluster connector

•	The radio connector

•	The multifunction alarm module connector C1

•	The cruise control module connector

•	The powertrain control module (PCM) connector C2

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

Does the measured voltage equal the specified value?

0 V
