PINPOINT TEST G251562p6: CHECK THE POWER AND GROUND SUPPLIES TO THE REM

G251562t31: CHECK THE IGNITION POWER SUPPLY TO THE REM
1. Disconnect the REM electrical connector, CR12.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between CR12, pin 08 (GU) and GROUND.

- Is the voltage less than 10 volts?

-> YES
REPAIR the circuit between the battery and the REM. This circuit includes the primary junction box (fuse 19).

-> NO
GO to Pinpoint Test G251562t32.

G251562t32: CHECK THE POWER SUPPLY FROM THE FUEL PUMP RELAY TO THE REM
1. Reconnect the REM electrical connector, CR12.
2. Disconnect the REM electrical connector, CR73
3. Make sure the fuel pump relay is energized.
4. Measure the voltage between CR73, pin 01 (N) and GROUND.

- Is the voltage less than 10 volts?

-> YES
REPAIR the circuit between the battery and the REM. This circuit includes the fuel pump relay and the rear power distribution box (fuse 33).

-> NO
GO to Pinpoint Test G251562t33.

G251562t33: CHECK THE GROUND TO THE REM
1. Measure the resistance between CR73, pins 02 and 15 (B) and GROUND.

- Is the resistance greater than 5 Ohms?

-> YES
REPAIR the high resistance circuit.

-> NO
CHECK for DTCs. Continue to pinpoint test indicated by the DTC.
