(DTC) Type Definitions)

Scan Tool Reference

Control Module References (See: Testing and Inspection/Programming and Relearning) for scan tool information

Circuit/System Verification

Verify with the scan tool that the BCM is reading the voltage correctly.

Circuit/System Testing

1. Turn the Ignition to ON.

2. Connect a DMM to the 14 volt battery.

3. Use the APM Low Voltage Control to turn on the APM 14 volt system. Vary the voltage setpoint with the scan tool ensuring that the DMM

tracks the commanded voltage.

瀚慖f the Low Voltage Control fails, replace the APM.

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 APM replacement, setup, and programming.
