Test Step 2 - (P199) HEATED SEAT SWITCH INDICATOR FEED CIRCUIT SHORTED TO VOLTAGE







• Turn the ignition off.

• Disconnect the Left Rear Heated Seat Switch harness connector.

• Disconnect the Left Rear Door Module C2 harness connector.

• Check connectors - Clean and repair as necessary.

• Measure the voltage between the (P181) Left Rear Heated Seat Switch Indicator Driver circuit and ground in the Left Rear Heated Seat Switch connector.

Is there any voltage present?

Yes

• Repair the (P181) Left Rear Heated Seat Low Indicator Driver circuit for a short to voltage.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

No

• Go to Test Step 3

Test Step 3 - (P329) PANEL LAMPS DRIVER CIRCUIT SHORTED TO VOLTAGE







• Measure the voltage between the (P329) Panel Lamps Driver circuit and ground in the Left Rear Heated Seat Switch connector.

Is there any voltage present?

Yes

• Repair the (P329) Panel Lamps Driver circuit for a short to voltage.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
