Sliding Roof Does Not Move By Operating Sliding Roof Control Switch
SLIDING ROOF: SLIDING ROOF SYSTEM: Sliding Roof does not Move by Operating Sliding Roof Control Switch
- Sliding Roof does not Move by Operating Sliding Roof Control Switch
DESCRIPTION
The sliding roof system uses a LIN communication protocol on the multiplex communication system. Inspect the communication system by following HOW TO PROCEED WITH TROUBLESHOOTING How To Proceed With Troubleshooting to ensure that there are no problems with the multiplex communication system before troubleshooting the sliding roof system. The sliding roof system prohibits the AUTO UP function if the jam protection function malfunctions. Check that there are no DTCs output before troubleshooting the sliding roof system. If any sliding roof system DTCs are output, perform troubleshooting on the output DTCs first.

INSPECTION PROCEDURE
PROCEDURE
1. INSPECT FUSE (ALT, S/ROOF, ECU-IG NO. 1)
(a) Remove the ALT fuse form the engine room main relay block.
(b) Remove the S/ROOF and ECU-IG No. 1 fuses from the instrument panel junction block.
(c) Measure the resistance of the fuses.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.
2. CHECK WIRE HARNESS (SLIDING ROOF CONTROL ECU - BATTERY AND BODY GROUND)
(a) Disconnect the Q12 connector.
(b) Measure the voltage and resistance according to the value(s) in the table below.
Standard voltage:
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. PERFORM ACTIVE TEST BY TECHSTREAM (SLIDING ROOF OPERATION)
(a) 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 Scan Tool Testing and Procedures.
Slide Roof:
OK:
Sliding roof operates normally.
NG -- REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF CONTROL ECU) Disassembly
OK -- Continue to next step.
4. READ VALUE USING TECHSTREAM (SLIDING ROOF CONTROL ECU)
(a) Use the DATA LIST to check if the sliding roof switch assembly is functioning properly Scan Tool Testing and Procedures.
Slide Roof:
NG -- REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF CONTROL ECU) Disassembly
OK -- Continue to next step.
5. READ VALUE USING TECHSTREAM (SLIDING ROOF SWITCH ASSEMBLY)
(a) Use the DATA LIST to check if the sliding roof switch assembly is functioning properly Scan Tool Testing and Procedures.
Slide Roof:
OK:
Techstream displays as shown in the table according to the operation of each switch.
NG -- INSPECT ROOF CONSOLE BOX ASSEMBLY (SLIDING ROOF SWITCH ASSEMBLY)
OK -- REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF CONTROL ECU) Disassembly
6. INSPECT ROOF CONSOLE BOX ASSEMBLY (SLIDING ROOF SWITCH ASSEMBLY)
(a) Remove the roof console box assembly.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE ROOF CONSOLE BOX ASSEMBLY (SLIDING ROOF SWITCH ASSEMBLY) Removal
OK -- Continue to next step.
7. CHECK WIRE HARNESS (SLIDING ROOF CONTROL ECU - ROOF CONSOLE BOX ASSEMBLY)
(a) Remove the Q12 and Q1 connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF CONTROL ECU) Disassembly
