W/Harness Inspection

Electronic Control Suspension
C2203 CDC Actuator Failure - FL - 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 in harness
1. IG "OFF"
2. Disconnect ECS damper connector and ECS ECU connector.
3. Measure resistance between High terminal of the ECS damper harness connector and High terminal of the ECS ECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specification?





Check for short in harness
1. IG "OFF"
2. Disconnect ECS damper connector and ECS ECU connector.
3. Measure resistance between High terminal of the ECS damper harness connector and chassis ground.

Specification : Infinite




4. Is the measured value within specification?






Control Circuit Inspection

Check for open in harness
1. IG "OFF"
2. Disconnect ECS damper connector and ECS ECU connector.
3. Measure resistance between Low terminal of the ECS damper harness connector and Low terminal of the ECS ECU harness connector.

Specification : Below approx. 1 Ohms




4. Is the measured value within specification?





Check for short in harness
1. IG "OFF"
2. Disconnect ECS damper connector and ECS ECU connector.
3. Measure resistance between Low terminal of the ECS damper harness connector and chassis ground.

Specification : Infinite
