Inspection Procedure

  1. CHECK HARNESS AND CONNECTOR (BATTERY - TRANSMISSION CONTROL SWITCH) 
    1. Disconnect the transmission control switch connector of shift lock control unit assembly.
    2. Measure the voltage according to the value(s) in the table below.

      Standard voltage 

      BATTERY - TRANSMISSION CONTROL SWITCH

      Switch Condition Tester Connection Specified Condition
      IG switch on (IG) 3 - Body ground 10 to 14 V
      IG switch OFF ↑ Below 1 V

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to Next Step 

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSIONA@CONTROL SWITCH - BODY GROUND) 
    1. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TRANSMISSIONA@CONTROL SWITCH - BODY GROUND

      Tester Connection Specified Condition
      7 (1) - Body ground
      5 (2) - Body ground      		 Below 1 Ω

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to Next Step 

  3. INSPECT TRANSMISSION CONTROL SWITCH 
    1. Measure resistance between each terminal of shift lock control unit assembly when the shift lever is moved to each position.

      Standard resistance (Check for short) 

    TRANSMISSION CONTROL SWITCH

    Shift Position Tester Connection Specified Condition
    S, "+" and "-" 3 - 9(1)
    3 - 7(2)    		 Below 1 Ω
    Except S, "+" and "-" ↑ 10 kΩ or higher
    Press continuously "+" (Up shift) 2 - 7(1)
    2 - 5(2)    		 Below 1 Ω
    S ↑ 10 kΩ or higher
    Press continuously "-" (Down shift) 1 - 7(1)
    1 - 5(2)    		 Below 1 Ω
    S ↑ 10 kΩ or higher
    (1) w/ Smart Key System

    (2) w/o Smart Key System

    NG: REPLACE TRANSMISSION CONTROL SWITCH 

    OK: Go to Next Step 

  4. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM) 
    1. Connect the transmission control switch connector of shift lock control unit assembly.
    2. Disconnect the ECM connector.
    3. Turn the ignition switch on (IG), and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

      Standard voltage 

      TRANSMISSION CONTROL SWITCH - ECM VOLTAGE

      Shift Position Tester Connection Specified Condition
      S, "+" and "-" D41 - 20(S) - Body ground 10 to 14 V
      Except S, "+" and "-" ↑ Below 1 V

    4. Turn the ignition switch off.
    5. Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.

      Standard resistance 

      TRANSMISSION CONTROL SWITCH - ECM (VOLTAGE)

      Shift Position Tester Connection Specified Condition
      Press continuously "+" (Up shift) D41 - 6 (SFTU) - Body ground Below 1 Ω
      S ↑ 10 kΩ or higher
      Press continuously "-" (Down shift) D41 - 5 (SFTD) - Body ground Below 1 Ω
      S ↑ 10 kΩ or higher
