Inspection Procedure

  1. INSPECT TRANSMISSION CONTROL SWITCH 
    1. Disconnect the L42 transmission control switch connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

    RESISTANCE REFERENCE

    Tester Connection Condition Specified Condition
    3 (IG) - 7 (S) Shift lever in S, "+" or "-" Below 1 Ω
    2 (SFTU) - 5 (E) Shift lever held in "+" (Up-shift) Below 1 Ω
    1 (SFTD) - 5 (E) Shift lever held in "-" (Down-shift) Below 1 Ω
    3 (IG) - 7 (S) Shift lever not in S, "+" or "-" 10 kΩ or higher
    2 (SFTU) - 5 (E) Shift lever in S 10 kΩ or higher
    1 (SFTD) - 5 (E) Shift lever in S 10 kΩ or higher

    NG: REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY (TRANSMISSION CONTROL SWITCH)  (See FLOOR SHIFT ASSEMBLY )

    OK: Go to next step. 

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND) 
    1. Disconnect the L42 transmission control switch connector.
    2. Turn the engine switch on (IG).
    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage 

      VOLTAGE SPECIFICATION

      Tester Connection Switch Condition Specified Condition
      L42-3 (IG) - Body ground Engine switch on (IG) 11 to 14 V
      L42-3 (IG) - Body ground Engine switch off Below 1 V
    4. Turn the engine switch off.
    5. Measure the resistance according to the value(s) in the table below.
