Transfer Fuel Pump G6, Checking

Transfer Fuel Pump G6, Checking

Special tools, testers and auxiliary items required
- Hand held remote control (jumper).
- Multimeter.
- Electrical connector test lead set.

Test requirements
- Battery voltage at least 12.5 volts.
- Fuse SD10 (on fuse panel D) OK.
- Fuse SD34 (on fuse panel D) OK.
- Fuel Pump (FP) Control Module J538 OK.
- Low Fuel Pressure Sensor G410 OK.

Checking voltage supply
- Remove the rear seat bench.







- Disconnect the Fuel Pump (FP) Control Module J538 electrical harness connector - arrow -.







- Using a Multimeter, check the Fuel Pump (FP) Control Module J538 electrical harness connector terminals 1 to 6 for voltage.

Specified value: battery (+).

If the specified value was not obtained:
- Check the wiring for a short circuit to Battery positive (+) or an open circuit.
- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
- If necessary, repair the electrical circuit.

If the specified value was obtained:







- Remove the cover - 1 - with the Fuel Pump (FP) Control Module J538 - 2 - attached, from the fuel pump.
- Disconnect the fuel pump electrical harness connector from the fuel pump.
- Connect a Hand held remote control (jumper) to terminal - 1 - of the fuel pump electrical harness connector and to the vehicle battery (+).







- Connect a jumper cable from a Electrical connector test lead set to terminal - 5 - of the fuel delivery unit and to vehicle Ground (GND).
- Press switch on the Hand held remote control (jumper).

NOTE: The Fuel Pump (FP) runs quietly. Avoid surrounding noises while testing the fuel pump.

- Listen for an operating noise from the fuel pump.

If no operating noise is heard:
- Remove the fuel delivery unit.







- Using a Multimeter, check the electrical circuit between terminals - 1 - and - 5 - of the fuel delivery unit and the fuel pump for continuity.

Specified value: 0 Ohms.

If a malfunction is detected in the electrical circuit:
- Check the wiring for a short circuit to Battery positive (+) or an open circuit.
- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
- If necessary, repair the electrical circuit.
- If no malfunction is detected in electrical circuit, replace the fuel pump.
- Assembly is performed in the reverse of the removal.

Final Procedures
After the repair work, the following work steps must be performed in the following sequence:

1. Check the DTC memory. Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase the DTC memory. Diagnostic Mode 04 - Erase DTC Memory
3. If the DTC memory was erased, generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes
