Lexus IS250 IS220d GSE20 ALE20 - SLIDING ROOF
PERFORM ACTIVE TEST BY INTELLIGENT TESTER (SLIDING ROOF OPERATION)
CHECK WIRE HARNESS (SLIDING ROOF ECU - MAP LIGHT ASSEMBLY)
SLIDING ROOF SYSTEM - 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) |
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
(Slide Roof)Operate sliding roof CLOSE/UP - SLIDE ROOF
(Slide Roof)Operate sliding roof OPEN/DOWN - - OK:
- Sliding roof operates normally.

| OK | |
| 2.INSPECT MAP LIGHT ASSEMBLY |
Disconnect the R5 connector.
Check the sliding roof switch.
Measure the resistance of the map light assembly.
- Standard resistance:
