Test C2 Continued:





Normal Operation
The adjustable brake and accelerator pedal memory function utilizes a variable resistor as an adjustable pedal potentiometer. The driver seat module (DSM), applies a reference voltage to the potentiometer. The output voltage to the DSM locates a specific pedal position. When the driver sets a pedal position in the DSM, the potentiometer output voltage is stored in memory. When the driver requests a return to a pedal position in memory, the DSM will operate the adjustable pedal motor until the adjustable pedal potentiometer output matches the voltage stored in memory.

Possible Causes
- Adjustable pedal potentiometer
- Open in circuits 446 (OG/WH), 447 (OG/RD) or 1491 (LB/YE)
- Driver Seat Module DSM
