Checking wiring
-- Using a Multimeter, Check the Fuel Pump Relay -J17- electrical harness connector terminals for resistance, Refer to applicable wiring diagram for fuse location and number.
| Fuel Pump Relay -J17- electrical harness connector terminals | Measure to: |
|---|---|
| 1 | Fuse, Refer to applicable wiring diagram for fuse location and number. |
| 3 | Fuse, Refer to applicable wiring diagram for fuse location and number. |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring connection for an open circuit, short circuit to Battery positive or Ground
-- Check the wiring connection for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection and replace any open fuses.
-- Go to Final procedures
If the specified value was obtained:
-- Install a jumper wire from Fuel Pump Relay -J17- Terminal 3 to 5
-- Switch the ignition ON.
The Fuel Pump (FP) runs quietly. Avoid surrounding noises while testing the fuel pump.
Specified value: Transfer Fuel Pump -G6- should be operating (Fuel Pump should be heard running).
-- Switch the ignition Off.
Continue test according to the following table:
| Value | Cause | Test |
|---|---|---|
| If the specified value was not obtained: | Open or shorted circuit | Checking wiring FUEL PUMP RELAY AND TRANSFER PUMP ELECTRICAL, CHECKING => Checking wiring |
| If the specified value was obtained: | Check reference signal circuit | Checking Activation FUEL PUMP RELAY AND TRANSFER PUMP ELECTRICAL, CHECKING => Checking Activation |
-- Remove the rear seat bench.
-- Remove cover retainers from the right sealing flange.
-- Disconnect the electrical harness connector from the Transfer Fuel Pump -G6- fuel delivery unit.
-- Using a multimeter, measure the resistance of the circuit between the Transfer Fuel Pump -G6- and the Fuel Pump Relay -J17-. Refer to the applicable wiring diagram.
| Transfer Fuel Pump -G6- electrical harness connector terminal | Measure to: |
|---|---|
| 1 | Fuel Pump Relay -J17- electrical connector terminal 5 |
| 5 | Engine Ground. |
Specified value: 1.5 Ω Max.
If the specification was not obtained:
-- Check the wires for a short circuit to each other, a short to battery voltage, and a short to ground.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-- Repair as necessary.
-- Go to Final procedures
If the specified value was obtained:
-- Replace the Transfer Fuel Pump -G6- delivery unit.
-- Go to Final procedures
