INSPECTION PROCEDURE

Note


  • When the sliding roof ECU (sliding roof drive gear assembly) is replaced or removed and reinstalled, it requires initialization Click here.

  • The sliding roof system uses LIN communication. First, confirm that there is no malfunction in the communication system by checking communication function of the LIN communication system. Refer to the How to Proceed with Troubleshooting procedure Click here.

PROCEDURE


  1. CHECK POWER WINDOW CONTROL SYSTEM (REMOTE UP/DOWN FUNCTION)


    1. Check that the each door power windows move when the remote up/down function of the multiplex network master switch assembly is operated Click here.

      OK
      Each door power windows up/down function is normal.

    NG

    GO TO POWER WINDOW CONTROL SYSTEM Click here

    OK

  2. INSPECT FUSE (RH ECU-IG)


    1. Remove the RH ECU-IG fuse from the driver side junction block*1 or passenger side junction block*2.


      • *1: for LHD

      • *2: for RHD

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      RH ECU-IG fuse Always Below 1 Ω

    NG

    REPLACE FUSE (RH ECU-IG)

    OK

  3. CHECK HARNESS AND CONNECTOR (SLIDING ROOF ECU - BATTERY)


    1. A01CBRYE04

      Install the RH ECU-IG fuse to the driver side junction block*1 or passenger side junction block*2.


      • *1: for LHD

      • *2: for RHD

    2. Disconnect the M2 ECU connector.

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      M2-9 (IG) - Body ground Engine switch on (IG) 11 to 14 V
      M2-9 (IG) - Body ground Engine switch off Below 1 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK SLIDING ROOF SYSTEM (BASIC FUNCTION)


    1. Reconnect the M2 ECU connector.

    2. Check the sliding roof basic function Click here.

      Result
      Result Proceed to
      Sliding roof does not operate by sliding roof switch (power slide door control switch) (for front side). A
      Sliding roof does not operate by sliding roof switch (integration control and panel assembly) (for rear side). B

      Tech Tips

      If the sliding roof does not operate by both front and rear side sliding roof switches, proceed to "A" first.

  5. CHECK HARNESS AND CONNECTOR (SLIDING ROOF ECU - SLIDING ROOF SWITCH)


    1. A01CBJSE05

      Disconnect the M2 ECU connector.

    2. Disconnect the R14 switch connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      M2-6 (OPN) - R14-3 (OPN) Always Below 1 Ω
      M2-7 (CLS) - R14-8 (CLS) Always Below 1 Ω
      R14-7 (E) - Body ground Always Below 1 Ω
      R14-3 (OPN) - Body ground Always 10 kΩ or higher
      R14-8 (CLS) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  6. INSPECT SLIDING ROOF SWITCH (POWER SLIDE DOOR CONTROL SWITCH) (for Front Side)


    1. A01CD6TE02

      Remove the sliding roof switch (power slide door control switch) (for front side) Click here.

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

      Standard Resistance

      3 (OPN) - 7 (E) Front sliding roof switch OPEN Below 1 Ω

      3 (OPN) - 7 (E)

      8 (CLS) - 7 (E)

      		 Front sliding roof switch off 10 kΩ or higher
      8 (CLS) - 7 (E) Front sliding roof switch CLOSE Below 1 Ω

    NG
