W/Harness Inspection

P0560 System Voltage

Inspection/Repair - W/Harness Inspection

Terminal & Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
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?






Power Circuit Inspection

Check Open in power circuit
1. IG KEY "OFF".
2. Disconnect Main relay and Key "ON".
3. Measure the voltage between Power from battery (30) terminal of main relay harness connector and chassis ground.
4. Measure the voltage between Power from battery (86) terminal of main relay harness connector and chassis ground.

Specification : B+




5. Is the measured voltage within specification?






Control Circuit Inspection

Check Open in control circuit
1. IG KEY "OFF".
2. Disconnect main relay and ECM connector.
3. Measure the voltage between Relay control terminal of main relay harness connector and ECM harness connector.

Specification : Approx 1 Ohms




4. Is the measured resistance within specification?






Power circuit inspection

Check Open in power circuit
1. IG KEY "OFF".
2. Disconnect main relay and ECM connector.
3. Measure the voltage between Power to component terminal of main relay harness connector and ECM harness connector.

Specification : Approx 1 Ohms




4. Is the measured resistance within specification?
