WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

B1 CHECK THE ADJUSTABLE PEDAL SWITCH REARWARD
- Disconnect: Adjustable Pedal Switch C2089.
- Press the adjustable pedal switch REARWARD and measure the resistance between the adjustable pedal switch C2089-3, circuit 32-AL19 (WH/GN), component side, and C2089-4, circuit 31-AL19A (BK/GN), component side.

- Is the resistance less than 5 ohms?
- Yes : GO to B2.
- No : INSTALL a new adjustable pedal switch. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
B2 CHECK THE ADJUSTABLE PEDAL SWITCH FORWARD
- Press the adjustable pedal switch FORWARD and measure the resistance between the adjustable pedal switch C2089-7, circuit 34-AL19 (BU/BK), component side, and C2089-4, circuit 31-AL19A (BK/GN), component side.
