Sliding Roof Control Switch Circuit
Circuit diagnosis
DESCRIPTION
The sliding roof drive gear (sliding roof ECU) receives slide switch and tilt switch signals and drives its built-in motor.WIRING DIAGRAM


INSPECTION PROCEDURE
| 1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER (SLIDING ROOF OPERATION) |
Select the Active Test, use the intelligent tester to generate a control command, and then check that the sliding roof slides open/close and tilts up/down.
