Component Testing
- Ignition OFF, disconnect the harness connector at the S48A Multifunction Switch - Instrument Panel.
- Test for infinite resistance between the signal circuit terminal 9 and the ground terminal 7 with the switch in the open position.
- If less than infinite resistance
Replace the S48A Multifunction Switch - Instrument Panel.
- If infinite resistance
- If less than infinite resistance
- Test for less than 2 Ω between the signal terminal 9 and the ground terminal 7 with the switch in the closed position.
- If 2 Ω or greater
Replace the S48A Multifunction Switch - Instrument Panel.
- If less than 2 Ω
- If 2 Ω or greater
- All OK.
