      Tester Connection Switch condition Specified Condition
      3 (IG) - 7 (S) Shift lever position S, "+" and "-" Below 1 Ω
      2 (SFTU) - 5 (E) Shift lever position continuously shift to "+" (Up-shift) Below 1 Ω
      1 (SFTD) - 5 (E) Shift lever position continuously shift to "-" (Down-shift) Below 1 a
      3(IG)-7(S) Shift lever position not on S, "+" and "-" 10 kΩ or higher
      2 (SFTU) - 5 (E) Shift lever position S 10 kΩ or higher
      1 (SFTD) - 5 (E) Shift lever position S 10 kΩ or higher

    NG: REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY (TRANSMISSION CONTROL SWITCH) (See  ON-VEHICLE INSPECTION   ) 

    OK: GO TO NEXT STEP 

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND)

      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 of the wire harness side connector.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Tester Connection Condition Specified Condition
      L42-5 (E) - Body ground Always Below 1 Ω

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: GO TO NEXT STEP 

  3. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
