Sun Roof System Circuit and Motor Inspection

Reference: SUN ROOF MOTOR REMOVAL AND INSTALLATION 

1. Check that sun roof switch is in good condition referring to SUN ROOF SWITCH INSPECTION .
2. Connect connector to sun roof switch.
3. Disconnect connector from sun roof motor.
4. Measure voltage and resistance between each terminals of sun roof motor connector (1).

   If each voltage and/or resistance are within specified value, sun roof system circuit is in good condition and proceed next step.

   If each voltage and/or resistance are out of specified value, repair sun roof system circuit.
