W/Harness Inspection

Electronic Control Suspension
C1247 Height Sensor - Front Right - W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness(es) and terminal condition.
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 for open
1. IG "ON"
2. Disconnect front-right height sensor connector.
3. Measure voltage between power terminal of front-right height sensor harness connector and chassis ground.

Specification : Approx. 5 V




4. Is the measured value within specifications?






Signal Circuit Inspection

Check for short
1. IG "OFF"
2. Disconnect front-right height sensor connector and ECS ECU connector.
3. Measure resistance between power terminal and signal terminal of front-right height sensor harness connector.
4. Measure resistance between ground terminal and signal terminal of front-right height sensor harness connector.

Specification : Infinite




5. Is the measured value within specifications?





Check for open
1. IG "OFF"
2. Disconnect front-right height sensor connector and ECS ECU connector.
3. Measure resistance between signal terminal of front-right height sensor harness connector and signal terminal of ECS ECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specifications?






Ground Circuit Inspection

Check for open
1. IG "OFF"
2. Disconnect front-right height sensor connector and ECS ECU connector.
3. Measure resistance between ground terminal of front-right height sensor harness connector and ground terminal of ECS ECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specifications?
