W/Harness Inspection

Body Control

Integrated Memory System - B1954 Slide Motor Or Sensor Error - W/Harness Inspection

Terminal and 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?






Signal Circuit Inspection

Check for open in harness
1. Ignition "OFF"
2. Disconnect powerseat slide motor.
3. Measure resistance between terminal "C7" of IMS and terminal "5" of powerseat slide sensor.
4. Measure resistance between terminal "D7" of IMS and terminal "6" of powerseat slide sensor.

Specification : Approx. 0 Ohms




5. Is the measured resistance within specifications?





Check for short in harness
1. Ignition "OFF"
2. Disconnect powerseat slide motor.
3. Measure resistance between terminal "5" and "6" of powerseat slide sensor and chassis ground

Specification : Approx. Infinity Ohms




4. Is the measured resistance within specifications?
