Sliding Roof Control Switch Circuit

DESCRIPTION

The sliding roof drive gear sub-assembly (sliding roof ECU) receives slide switch and tilt switch signals and drives its built-in motor.

INSPECTION PROCEDURE

1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER (SLIDING ROOF OPERATION)

1. 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.

SLIDE ROOF:

Item	Test Details	Diagnostic Note
SLIDE ROOF	Operate sliding roof CLOSE/UP	-
SLIDE ROOF	Operate sliding roof OPEN/DOWN	-

OK:

Sliding roof operates normally.

NG	REPLACE SLIDING ROOF ECU

OK

2. INSPECT MAP LIGHT ASSEMBLY

1. Disconnect the R5 connector.

2. Check the sliding roof switch.

3. Measure the resistance of the map light assembly.
