Signal Circuit Inspection

■ Check for open in harness 

1. Ignition "OFF"
2. Disconnect front height motor.
3. Measure resistance between terminal "C3" of IMS and terminal "4" of front height sensor.
4. Measure resistance between terminal "D4" of IMS and terminal "1" of front 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.

■ Check for short in harness 

1. Ignition "OFF"
2. Disconnect front height motor.
3. Measure resistance between terminal "1" and "4" of front height sensor and chassis ground

   Specification  : Approx. ∞ Ω
