Brakes and Traction Control: Description and Operation

DESCRIPTION AND OPERATION

Brake System
The brake system has the following components:
^ a vacuum assisted power braking system
^ a front to rear split hydraulic system
^ front disc brakes use a dual piston brake caliper and disc system
^ rear disc brakes use a single piston brake caliper and disc system
^ a mechanical parking brake system that activates a drum in hat system within the rear brake disc
^ a 4 Wheel Anti-Lock Brake System (4WABS).
^ adjustable pedals
^ adjustable pedals with memory
^ fixed pedals

This vehicle is equipped with an electronic throttle control.

Adjustable Pedals
The vehicle is equipped with an adjustable brake and accelerator pedal system. Using the adjustable pedal switch located on the instrument panel, the driver can adjust the brake and accelerator pedals for a more comfortable driving position.

Adjustable Pedal Operation
The adjustable pedals with or without memory feature are operational with the ignition switch in the ON or OFF position. The pedals can be adjusted forward or rearward using the adjustable pedal switch.

Driver Seat Module
The Driver Seat Module (DSM) controls the memory adjustable pedals.

The DSM constantly monitors the systems under its control and reports a concern in the form of Diagnostic Trouble Codes (DTCs). A DTC can be retrieved with the diagnostic tool through the Data Link Communications (DLC).

Memory Adjustable Pedal Operation
The adjustable pedals with memory feature can be controlled by using the memory switches or the Remote Keyless Entry (RKE) 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 3 memory settings.

Programming Adjustable Pedal Positions
Programming adjustable pedal positions can be accomplished by doing the following:
^ An adjustable pedal position can be stored at any time. To store the adjustable pedal position to memory, the driver must move the pedals to the preferred position using the adjustable pedal switch. The driver must then press the memory SET switch, activating the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out) the driver must select memory position 1, 2, or 3.
^ If no memory switch input is received within the 5 second time limit, the operation is aborted and the memory SET switch LED is turned off. If one of the following inputs is received during the 5 second programming limit, the operation is aborted and the memory SET switch LED is turned off:
^ Adjustable pedal switch
^ Power driver seat switch
^ Exterior mirror control switch
^ Memory SET switch

Recalling a Stored Adjustable Pedal Position
Once the driver has stored a preferred adjustable pedal position, the driver can recall the setting by pressing the corresponding memory switch, or by using a programmed remote keyless entry (RKE) transmitter. Recalling a stored adjustable pedal position can be accomplished by doing the following:
^ The driver can recall a preferred adjustable pedal position by pressing one or both of the memory recall switches. Pressing memory switch 1 initiates a recall of the adjustable pedal position stored in memory location 1. Pressing memory switch 2 initiates a recall of the adjustable pedal position stored in memory location 2. Pressing both memory switch 1 and memory switch 2 initiates a recall of the adjustable pedal position stored in memory location 3.
^ A remote transmitter can be used to recall previously set memory positions. The RKE transmitters are manufactured with an assigned personality number (1, 2, or 3) and are so designated on the back of the RKE transmitter case. The RKE transmitter assigned with personality 1 is capable of only recalling memory position 1. Similarly, the RKE transmitters assigned with personalities 1, 2, and 3 can recall memory positions 1, 2, and 3 respectively.
^ Memory recall occurs when the UNLOCK switch is pressed on the RKE transmitters. A second press of the UNLOCK switch, which unlocks the passenger doors, does not initiate a memory recall.
^ A memory recall in progress does not prohibit the initiation of another memory recall; the most recently requested memory recall is executed.
