      NG (for AWD model) C

    B → REPLACE COMBINATION SWITCH ASSEMBLY 

    C → REPLACE COMBINATION SWITCH ASSEMBLY 

    A: Go to next step 

  3. CHECK HARNESS AND CONNECTOR (ECM - COMBINATION SWITCH ASSEMBLY) 
    1. Disconnect the combination switch assembly connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      A21-22 (SNWI) - N59-2 (2ND) Always Below 1 Ω
      A21-22 (SNWI) or N59-2 (2ND) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (COMBINATION SWITCH ASSEMBLY - BODY GROUND) 
    1. Disconnect the combination switch assembly connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      N59-4 (GND) - Body ground Always Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
