Inspection Procedure

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

      Voltage 

      VOLTAGE SPECIFICATION

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

    NG : REPAIR OR REPLACE HARNESS OR CONNECTOR

  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.

      Resistance 

      RESISTANCE SPECIFICATION

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

    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 engine 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.

      Voltage 

      VOLTAGE SPECIFICATION

      Shift Position Tester Connection Specified Condition
      S, "+" and "-" A7 - 9 (S) - Body ground 10 to 14 V
      Except S, "+" and "-" ↑ Below 1 V

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

      Resistance 

      RESISTANCE SPECIFICATION

      Shift Position Tester Connection Specified Condition
      Press continuously "+" (Up shift) A7 - 30 (SFTU) - Body ground Below 1 Ω
      S ↑ 10 kΩ or higher
      Press continuously "-" (Down shift) A7 - 19 (SFTD) - Body ground Below 1 Ω
      S ↑ 10 kΩ or higher
