* 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.

Diagnostic Fault Information

Circuit/System Description

The control modules on this vehicle monitor the battery voltage on the 12V battery positive (B+) voltage circuits. This vehicle has multiple modules

that will set the DTC. For information about which modules, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble

Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).

Conditions for Running the DTC

* The 12V battery voltage supplied to the control modules is in the range of 7-26 volts.

* The engine is running.

Conditions for Setting the DTC
