Component Testing

  1. Ignition OFF, disconnect the harness connector at the S38 Ignition Mode Switch.
  2. Test for 4.5-5.5 kΩ between the terminals listed below with the S38 Ignition Mode Switch released,
    • Signal terminal 6 and ground terminal 4
    • Signal terminal 3 and low reference terminal 7
    • If not between 4.5-5.5 kΩ 

      Replace the S38 Ignition Mode Switch.

    • If between 4.5-5.5 kΩ 
  3. Test for 1-1.5 kΩ between the terminals listed below with the S38 Ignition Mode Switch pressed.
    • Signal terminal 6 and ground terminal 4
    • Signal terminal 3 and low reference terminal 7
    • If not between 1-1.5 kΩ 

      Replace the S38 Ignition Mode Switch.

    • If between 1-1.5 kΩ 
  4. All OK.


S39 Ignition Switch

  1. Ignition OFF, disconnect the X1 harness connector at the S39 Ignition Switch.
  2. Using the Resistance Test below, verify the resistance between the terminals listed below match for each S39 Ignition Switch Position.
    • If any reading is other than specified 

      Replace the S39 Ignition Switch.

    • If the readings match 
  3. All OK.
