SUNROOF MOTOR INSPECTION
id091500801100
1. Measure the voltage at each terminal (other than terminal G).
2. Disconnect the negative battery cable.
3. Verify that continuity at terminal G is as indicated in the Terminal Voltage Table (Reference).
4. If the parts and wiring harnesses are normal but the system still does not work properly, replace the sunroof relay.
