Pinpoint Test B: Manual Switch Does Not Move The Adjustable Pedals - Memory Is Functional

WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

B1 MONITOR THE DRIVER SEAT MODULE (DSM) PID FOR THE ADJUSTABLE PEDAL SWITCH
- Monitor the DSM adjustable pedal switch PID with the adjustable pedal switch in each direction.
- Doe the PID reading agree with the switch position?
Yes GO to B6.

No GO to B2.
B2 CHECK THE ADJUSTABLE PEDAL SWITCH FWD
- Disconnect: Adjustable Pedal Switch C2089.
- Push the adjustable pedal switch UP (forward position) and measure the resistance between the adjustable pedal switch C2089-1, circuit 1493 (PK/BK), component side and the adjustable pedal switch C2089-2, circuit 490 (RD), component side.
- Is the resistance less than 5 ohms?
Yes GO to B3.

No INSTALL a new adjustable pedal switch. TEST the system for normal operation.
B3 CHECK THE ADJUSTABLE PEDAL SWITCH RWD
- Push the adjustable pedal switch DOWN (rearward position) and measure the resistance between the adjustable pedal switch C2089-7, circuit 1492 (LB/RD), component side and the adjustable pedal switch C2089-2, circuit 490 (RD), component side.
- Is the resistance less than 5 ohms?
Yes GO to B4.

No INSTALL a new adjustable pedal switch. TEST the system for normal operation.
B4 CHECK CIRCUIT 490 (RD)
- Measure the resistance between the adjustable pedal switch C2089-2, circuit 490 (RD) harness side and ground.
- Is the resistance less than 5 ohms?
Yes GO to B5.

No REPAIR circuit 490 (RD). TEST the system for normal operation.

B5 CHECK THE CIRCUITS BETWEEN THE DSM AND THE ADJUSTABLE PEDAL SWITCH

Key in OFF position.
Disconnect: DSM C341g.

Measure the resistance between the adjustable pedal switch and ground; and between the adjustable pedal switch and the DSM as follows:

PEDAL SWITCH SPECIFICATION

Adjustable Pedal Switch C2089	DSM C341g
C2089-1, circuit 1493 (PK/BK)	C341g-8, circuit 1493 (PK/BK)
C2089-7, circuit 1492 (LB/RD)	C341g-9, circuit 1492 (LB/RD)

Are the resistances less than 5 ohms between the adjustable pedal switch and the DSM, and greater than 10,000 ohms between the adjustable pedal switch and ground?

Yes GO to B6.

No REPAIR the circuit in question. TEST the system for normal operation.

B6 CHECK FOR CORRECT DSM OPERATION
- Disconnect all DSM connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all DSM connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes INSTALL a new DSM. REFER to MODULE COMMUNICATIONS NETWORK . REPEAT the self-test.

No The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
