Signal Circuit Inspection

■ Check for open in harness 

1. Ignition "OFF"
2. Disconnect rear height motor.
3. Measure resistance between terminal "C8" of IMS and terminal "4" of rear height sensor.
4. Measure resistance between terminal "C9" of IMS and terminal "1" of rear height sensor.

   Specification  : Approx. 0 Ω

5. Is the measured resistance within specifications?

   YES 

   • Go to  1 Check for short in harness procedure.

   NO 

   • Check for open in signal harness. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
