Parking Assist Switch Indicator Circuit Malfunction

Ignition OFF, disconnect the harness connector at the S48D Multifunction Switch 2 - Instrument Panel, Ignition ON.
Test for greater than 11 V between the terminal 3 and ground.
- If less than 11 V
  Test the voltage circuit for a short to ground or an open/high resistance.
- If greater than 11 V
Command the Park Assist Switch LED output control ON with the scan tool. Test for greater than 11 V between the ignition circuit terminal 3 and the signal circuit terminal 5.
- If less than 11 V
  Test the signal circuit for an open/high resistance.
- If greater than 11 V
Command the Park Assist Switch Indicator Off with the scan tool.
Test for less than 1 V between the terminal 6 and ground.
- If 1 V or greater
  Test the signal circuit for a short to voltage.
If all circuits test normal, replace the S48D Multifunction Switch 2 - Instrument Panel.
