Sliding Roof does not Move by Operating Sliding Roof Control Switch: Procedure

1. Remove the DC/DC fuse from the engine room main relay block.
2. Remove the S/ROOF and ECU-IG No. 1 fuses from the instrument panel junction block.
3. Measure the resistance of the fuses.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   DC/DC fuse	Always	Below 1 Ω
   S/ROOF fuse	Always	Below 1 Ω
   ECU-IG No. 1 fuse	Always	Below 1 Ω

NG → REPLACE FUSE 

OK: Go to next step 

1. Disconnect the Q12 connector.

2. Measure the voltage and resistance according to the value(s) in the table below.

   Standard voltage

   Tester Connection	Condition	Specified Condition
   Q12-1 (B) - Body ground	Always	10 to 14 V
   Q12-5 (IG) - Body ground	Ignition switch ON	10 to 14 V
   Q12-5 (IG) - Body ground	Ignition switch off	Below 1 V

   Standard resistance

   Tester Connection	Condition	Specified Condition
   Q12-2 (E) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Select the Active Test, use the Techstream to generate a control command, and then check that the sliding roof slides open/close and tilts up/down. Refer to DATA LIST / ACTIVE TEST .
   SLIDE ROOF:
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Slide Roof	Operate sliding roof SLIDE CLOSE/TILT UP	Clos/Up: Sliding roof SLIDE CLOSE or TILT UP operation occurs. OFF: Sliding roof is not operating.	-
   Slide Roof	Operate sliding roof SLIDE OPEN/TILT DOWN	Opn/Dwn: Sliding roof SLIDE OPEN or TILT DOWN operation occurs. OFF: Sliding roof is not operating.	-

   OK

   Sliding roof operates normally.
