Shift Lock System: Inspection

  1. INSPECT KEY INTER LOCK SOLENOID 
    1. Measure the resistance of the solenoid.

      Standard resistance 

      RESISTANCE REFERENCE CHART

      Tester Connection Specified Condition
      5 (SLS+) - 4 (SLS-) 20 to 27 Ω

      If the result is not as specified, replace the solenoid.

    2. Apply positive (+) battery voltage between the terminals. Check that sounds are emitted from the operating solenoid.

      If sounds are not emitted, replace the solenoid.

      HINT:

      If sounds are not emitted from the solenoid, the solenoid is not operating.

  2. INSPECT SHIFT LOCK CONTROL SWITCH 
    1. Measure the resistance of the switch.

      Standard resistance 

      RESISTANCE REFERENCE CHART

      Tester Connection Shift Lever Position Specified Condition
      3 (P1) - 2 (P) P (shift lock release button is not pushed Below 1 Ω
      3 (P1) - 2 (P) P (shift lock release button is pushed Below 1 Ω
      1 (P2) - 2 (P) R, N, D, 2, L Below 1 Ω

      If the result is not as specified, replace the switch.

  3. INSPECT KEY INTERLOCK SOLENOID 
    1. Measure the resistance of the solenoid.

      Standard resistance 

      RESISTANCE REFERENCE CHART

      Tester Connection Specified Condition
      1 (KLS-) - 2 (KLS+) 12 to 17 Ω

      If the result is not as specified, replace the key interlock solenoid.

    2. Connect the battery's positive (+) terminal to terminal 2 (KLS+) and the battery's negative (-) terminal to terminal 1 (KLS-). Check that sounds are emitted from the operating solenoid. If sounds are not emitted, replace the solenoid.

      HINT:

      If sounds are not emitted from the solenoid, the solenoid is not operating.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
