Terminal and Connector inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal connections.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found ?






Signal Circuit Inspection

Check voltage
1. IG "OFF" and disconnect Fuel Sender & Fuel Pump Motor connector and cluster connector.
2. IG "ON".
3. Measure voltage between Fuel Sender Input signal terminal of Fuel Sub Sender harness connector and chassis ground.

Specification :Approx. 0V




4. Is the measured voltage within specification ?






Ground Circuit Inspection

Check open in harness
1. IG "OFF" and disconnect Instrument cluster connector and Fuel Sender connector.
2. Measure resistance between ground terminal of Fuel Sender harness connector and Fuel ground terminal of Instrument cluster harness connector.

Specification :Below 1Ohms




3. Is the measured resistance within specification ?
