Performing the Multimeter Test

  1. Setting Up: Set your multimeter to the ohms (Ω) scale.
  2. Test in Neutral: Connect multimeter probes to the switch’s terminals. The multimeter should indicate continuity when the car is in Neutral.
  3. Test in Gear: Change your car to a gear other than Neutral or Park. The multimeter should indicate no continuity.

Interpreting Results

  • Consistent Readings: If your readings align with the test, your switch is likely in good condition.
  • Inconsistent Readings: An inconsistent reading usually indicates a faulty switch that should be replaced.
