Pinpoint Test G239843P13

PINPOINT TEST G239843p13 : CHECK THE SUPPLIES AND GROUNDS TO THE FRONT ELECTRONIC MODULE

G239843t69 : CHECK THE PERMANENT SUPPLY TO THE FEM
1. Disconnect the FEM electrical connector, CR09.
2. Measure the voltage between CR09, pin 06 (NW) and GROUND.

- Is the voltage less than 10 volts?

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

-> NO

G239843t70 : CHECK THE SWITCHED SYSTEM POWER (SSP) SUPPLY TO THE FEM
1. Reconnect the FEM electrical connector, CR09.
2. Disconnect the FEM electrical connector, CR01.
3. Make sure the SSP relay is energized.
4. Measure the voltage between CR01, pins 07 and 08 (NW) and GROUND.

- Is the voltage less than 10 volts?

-> YES
REPAIR the circuit between the FEM and battery. This circuit includes the primary junction box (fuse 47) and the SSP relay. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G239843t71.

G239843t71 : CHECK THE GROUND TO THE FEM
1. Reconnect the FEM electrical connector, CR01.
2. Disconnect the FEM electrical connector, CR10.
3. Measure the resistance between CR10, pins 11 and 13 (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.
