Adjustable Foot Pedal System Operation

Depressing the adjustable foot pedal switch sends a hardwired, resistor multi-plexed signal to the drivers door module. The door module then sends a PCI data bus message to the Memory Heated Seat/Adjustable Pedal Module (MHSAPM). The module detects the adjustable pedal switch status via the PCI data bus circuit and energizes the appropriate foot pedal motor. When the foot pedal switch is released the module will stop the motor.

Depressing the memory switch will signal the module to move the pedal assembly to the preprogrammed position. The programmed software in the MHSAPM allows it to know the location of the foot pedal assembly by a resistance value generated from the pedal assembly mounted potentiometer. When the correct preset location is achieved the module will de-energize the foot pedal motor. The MHSAPM will prevent the adjustable foot pedal function from being initiated if the transmission gear selector lever is not in the Park or Neutral positions, or if the vehicle is moving. These inputs are monitored over the PCI data bus circuit also.
