Honda Civic. Manual — part 949

Check the ECM/PCM DTCs. If there is no DTC, jump the SCS line with
the HDS, then disconnect the ECM/PCM connector A (44P), and the
moonroof control unit/motor 10P connector.

Make these input tests at the connector.

If any test indicates a problem, find and correct the cause, then
recheck the system.

If all the input tests prove OK, the control unit must be faulty; replace
the moonroof control unit/motor.
