Circuit/System Testing

1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and

15.0 volts.

瀚慖f not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and Inspection/Component Tests

and General Diagnostics/Charging System Test).

2. Ignition OFF, disconnect the harness connectors at the appropriate module.

3. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the

appropriate ground circuit terminals listed below and ground.

* Terminal 5 (PPS)

* Terminal 13 (IPC)

* Terminal 8 X1 (amplifier, radio)

* Terminal 7 X2 (rear object)

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

4. Verify that a test lamp illuminates between the appropriate B+ circuit terminals listed below and ground.

* Terminal 1 (IPC, PPS)

* Terminal 1 X1 (radio)

* Terminal 4 X1 (amplifier)

* Terminal 1 X2 (rear object)

瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

5. If all circuits test normal, replace the appropriate module.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Control Module References (See: Testing and Inspection/Programming and Relearning) for the appropriate module replacement, setup, and

programming.
