Fuel Pump Unit Inspection
Continuity InspectionNOTE: Perform the following test only when directed.
1. Disconnect the negative battery cable.
2. Remove the rear seat cushion.
3. Remove the service hole cover.
4. Disconnect the fuel pump unit connector.
5. Inspect for continuity between fuel pump unit connector terminals B and D.
- If there is no continuity, replace the fuel pump body.
- If as specified, carry out the "Circuit Open/ Short Inspection".
Circuit Open/Short Inspection
1. Remove the PCM.
2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.
Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}
4. Inspect for an open or short circuit in the following wiring harnesses by probing the applicable sensor and SST(104 Pin Breakout Box) terminals with ohmmeter leads.
Open circuit
- GND circuit (Fuel pump unit connector terminal D and body GND)
- Power circuit (Fuel pump relay connector terminal C and fuel pump unit connector terminal B through common connector)
Short circuit
- Fuel pump relay connector terminal C and fuel pump unit connector terminal B through common connector to GND
5. Repair or replace faulty areas.
6. Reconnect the fuel pump unit connector.
7. Install the service hole cover.
8. Install the rear seat cushion.
9. Reconnect the negative battery cable.
