SLIDING ROOF SYSTEM 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 Click here 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/DOWN 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 (S/ROOF, ECU-IG NO. 1)


    1. Remove the S/ROOF and ECU-IG No. 1 fuses from the instrument panel junction block.

    2. Measure the resistance of the fuses.

      Standard resistance
      Below 1 Ω

    NG

    REPLACE FUSE

    OK

  2. CHECK WIRE HARNESS (SLIDING ROOF CONTROL ECU - BATTERY AND BODY GROUND)


    1. A017B8QE14

      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 (IG) 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

  3. 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 Click here.
