REAR SUNSHADE SYSTEM Front and Rear Switch Cannot Operate Rear Sunshade

DESCRIPTION

A rear sunshade switch signal is sent from the integration control and panel assembly to the combination switch assembly. Then the signal is sent through LIN communication to the outer mirror switch, which then sends the signal through CAN communication to the rear junction block ECU, and the rear sunshade operates. A rear sunshade signal is sent from the rear power seat switch to the rear junction block ECU, and the rear sunshade operates.

    NG
    OK
  4. INSPECT FUSE (RR S/SHADE)


    1. Remove the RR S/SHADE fuse from luggage room junction block.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      RR S/SHADE fuse Always Below 1 Ω

    NG
    OK

      Standard resistance
      Tester Connection Condition Specified Condition
      LG-1 - Body ground Always 11 to 14 V

    NG
    OK
  6. CHECK HARNESS AND CONNECTOR (REAR SUNSHADE - REAR JUNCTION BLOCK AND BODY GROUND)


    1. A000ZI9E01

      Disconnect the S25 shade connector.

    2. Disconnect the S61 ECU connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition

      S25-2 (RSMU) - Body ground Always 10 kΩ or higher
      S25-1 (RSMD) - Body ground Always 10 kΩ or higher

    NG
    OK
  7. INSPECT REAR SUNSHADE ASSEMBLY


    1. A000YJZE60
      *1 Component without harness connected: (Rear Sunshade Assembly)
      *2 RSMD
      *3 RSMU

      Remove the rear sunshade assembly Click here.

    2. Apply battery voltage and check the operation of the window shade motor.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → 1 (RSMD)

      Battery negative (-) → 4 (RSE)

      Sunshade lowers

      Battery positive (+) → 2 (RSMU)

      Battery negative (-) → 4 (RSE)

      Sunshade raises

    OK
    NG
  8. CHECK HARNESS AND CONNECTOR (REAR SUNSHADE ASSEMBLY - REAR JUNCTION BLOCK AND BODY GROUND)


    1. A000WQFE01
