- Select PARK.
- Press the unlock button on the RKE (Remote Keyless Entry) transmitter and observe the following items:
- Driver seat
- Exterior mirrors
- Adjustable pedals
Do all 3 items move when the button is pressed?
Yes
GO to B4.
No
If all 3 items do not move, REFER to Diagnosis and Testing in Doors, Hood and Trunk &/or Locks to DIAGNOSE the RKE (Remote Keyless Entry) transmitter. Testing and Inspection
If only the adjustable pedals do not move, GO to B4.
If only the driver seat does not move, REFER to Diagnosis and Testing in Seats. Testing and Inspection
If only the exterior mirrors do not move, REFER to Diagnosis and Testing in Mirrors. Testing and Inspection
B4 CHECK THE ADJUSTABLE PEDAL MOTOR AND CABLE INSTALLATION
- Check the adjustable pedal motor and cable for correct installation.
Are the motor and cable correctly installed?
Yes
GO to B5.
No
CORRECT the adjustable pedal motor installation. TEST the system for normal operation.
B5 INSPECT FOR FOREIGN MATERIAL
- Inspect the adjustable brake pedal and accelerator assemblies for foreign material causing a binding condition.
Are the pedal assemblies free from foreign material?
Yes
GO to B6.
No
REMOVE the foreign material. TEST the system for normal operation.

- Disconnect: Adjustable Pedal Motor C2159.
- Disconnect: DSM (Driver Seat Module) C341C.
- Measure the resistance between DSM (Driver Seat Module) C341C, harness side and adjustable pedal motor C2159, harness side as indicated in the following chart:
DSM (Driver Seat Module) Circuit Adjustable Pedal Motor C341C-12 CPP01 (WH/OG) C2159-2 C341C-24 CPP02 (BN) C2159-1 C341C-15 RPP06 (GN) C2159-3 C341C-3 LPP06 (YE/BU) C2159-4
Are the resistances less than 5 ohms?
Yes
GO to B7.
No
REPAIR the affected circuit(s). TEST the system for normal operation.
B7 CHECK THE DSM (Driver Seat Module) PEDAL MOTOR AND HALL-EFFECT CIRCUITS FOR A SHORT TO GROUND
- Measure the resistance between ground and:
- DSM (Driver Seat Module) C341C-3, circuit LPP06 (YE/BU), harness side.
- DSM (Driver Seat Module) C341C-12, circuit CPP01 (WH/OG), harness side.
- DSM (Driver Seat Module) C341C-15, circuit RPP06 (GN), harness side.
- DSM (Driver Seat Module) C341C-24, circuit CPP02 (BN), harness side.
Are the resistances greater than 10,000 ohms?
Yes
GO to B8.
No
REPAIR the affected circuit(s). TEST the system for normal operation.
B8 CHECK THE DSM (Driver Seat Module) PEDAL MOTOR AND HALL-EFFECT CIRCUITS FOR A SHORT TOGETHER
- Measure the resistance between DSM (Driver Seat Module) C341C pins, harness side as indicated in the following chart:
DSM (Driver Seat Module) Circuit DSM (Driver Seat Module) Circuit C341C-3 LPP06 (YE/BU) C341C-12 CPP01 (WH/OG) C341C-3 LPP06 (YE/BU) C341C-15 RPP06 (GN) C341C-3 LPP06 (YE/BU) C341C-24 CPP02 (BN) C341C-12 CPP01 (WH/OG) C341C-15 RPP06 (GN) C341C-12 CPP01 (WH/OG) C341C-24 CPP02 (BN) C341C-15 RPP06 (GN) C341C-24 CPP02 (BN)
