Adjustable Pedal Operation
The adjustable pedals with memory feature are operational with the ignition switch ON or OFF. The pedals can be adjusted forward or rearward using the adjustable pedal switch.
Memory Adjustable Pedal Operation
The adjustable pedals with memory feature can be controlled by using the memory switches or the remote keyless entry transmitter. The outside rearview mirror and power driver seat positions are also stored and recalled with the power adjustable pedal positions. The system can store three memory settings.
Normal Operation
The adjustable pedal system uses a two-way motor to rotate cables that move the brake and accelerator pedal assemblies toward or away from the driver. The adjustable pedal switch receives power at all times from circuit 490 (RD). When the adjustable pedal switch is pressed in the forward or rearward position, power flows through circuit 1492 (LB/RD) (rearward) or circuit 1493 (PK/BK) (forward) to the adjustable pedal motor. Grounds are provided through circuit 1205 (BK).
The manual switch for the adjustable pedals receive power from circuit 490 (RD) at all times through circuit 1492 (LB/RD) and circuit 1493 (PK/BK). The switch receives ground through circuit 1205 (BK). Pushing the switch upward closes circuit 1493 (PK/BK) and the adjustable pedal motor moves the pedals toward the driver. Pushing the switch downward closes circuit 1492 (LB/RD) and the adjustable pedal motor moves the pedals away from the driver.
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.
The two-way adjustable pedal motor receives power from the driver seat module through circuit 1489 (LB/BK) (forward) and circuit 1490 (LB/OG) (rearward). The motor runs until the manual switch is released, until the travel limit is reached, or until the stored memory position is reached.
Depending on pedal position, the adjustable pedal potentiometer sends a resistance through feed back circuit 1491 (LB/YE) to the DSM; that value is stored in the DSM memory for recalling the position of the adjustable pedals.
Circuit 446 (OG/WH) carries a reference voltage from the DSM to the adjustable pedal potentiometer.
Circuit 447 (OG/RD) carries return voltage from the adjustable pedal potentiometer to the other DSM controlled memory system components.
