Component Testing

Ignition OFF, disconnect the harness connector at the S48D multifunction switch 2 - instrument panel.
Test for infinite resistance between the signal circuit terminal 7 and the ground circuit terminal 2 with the switch in the open position.
- If less than infinite resistance
  Replace the S48D multifunction switch 2 - instrument panel.
- If infinite resistance
Test for less than 2 Ω between the signal circuit terminal 7 and the ground circuit terminal 2 with the switch in the closed position.
- If 2 Ω or greater
  Replace the S48D multifunction switch 2 - instrument panel.
- If less than 2 Ω
All OK.
