Pinpoint Test G239843P14

PINPOINT TEST G239843p14 : CHECK THE SUPPLIES AND GROUNDS TO THE REAR ELECTRONIC MODULE

G239843t72 : CHECK THE PERMANENT SUPPLY TO THE REM
1. Disconnect the REM electrical connector, CR04.
2. Measure the voltage between CR04, pin 03 (NW) and GROUND.

- Is the voltage less than 10 volts?

-> YES
REPAIR the circuit between the REM and battery. This circuit includes the primary junction box (fuse 42). TEST the system for normal operation.

-> NO

G239843t73 : CHECK THE SWITCHED SYSTEM POWER (SSP) SUPPLY TO THE REM
1. Reconnect the REM electrical connector, CR04.
2. Disconnect the REM electrical connector, CR13.
3. Make sure the SSP relay is energized.
4. Measure the voltage between CR13, pin 06 (N) and GROUND.

- Is the voltage less than 10 volts?

-> YES
REPAIR the circuit between the REM and battery. This circuit includes the primary junction box (fuse 13) and the SSP relay. TEST the system for normal operation.

-> NO

G239843t74 : CHECK THE GROUND TO THE REM
1. Reconnect the REM electrical connector, CR13.
2. Disconnect the REM electrical connector, CR11.
3. Measure the resistance between CR11, pins 11 and 25 (B) and GROUND.

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. TEST the system for normal operation.

-> NO
CHECK for DTCs indicating a network or module fault. REFER to the DTC index.
