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.

    Voltage 

    BATTERY - TRANSMISSION CONTROL SWITCH

    Switch Condition Tester Connection Specified Condition
    IG switch ON 3 - Body ground 10 to 14 V
    IG switch OFF Below 1 V

    Resistance (Check for short) 

    TRANSMISSION FLOOR SHIFT ASSEMBLY (CHECK FOR SHORT)

    Shift Position Tester Connection Specified Condition
    S, "+" and "-" 3 - 8 Below 1 Ω
    Except S, "+" and "-" 10 kΩ or higher
    Press continuously "+" (Up shift) 4 - 10 Below 1 Ω
    S 10 kΩ or higher
    Press continuously "-" (Down shift) 5 - 10 Below 1 Ω
    S 10 kΩ or higher

    NG: REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY 

    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. Turn the ignition switch to the ON position, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

      Voltage 

      TRANSMISSION CONTROL SWITCH - ECM (VOLTAGE)

      Shift Position Tester Connection Specified Condition
      S, "+" and "-" E6 - 23 (S) - Body ground 10 to 14 V
      Except S, "+" and "-" Below 1 V
    3. Turn the ignition switch to the LOCK position.
    4. Disconnect the ECM connector.
    5. Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.

    Resistance 

    TRANSMISSION CONTROL SWITCH - ECM (RESISTANCE)

    Shift Position Tester Connection Specified Condition
    Press continuously "+" (Up shift) E6 - 22 (SFTU) - Body ground Below 1 Ω
    S 10 kΩ or higher
    Press continuously "-" (Down shift) E6 - 21 (SFTD) - Body ground Below 1 Ω
    S 10 kΩ or higher
