Electronic Brake Control Module: Description and Operation
NOTE: The anti-lock brake control module must be reconfigured upon replacement.
The anti-lock brake control module is an on-board, diagnostic, non-repairable unit consisting of two microprocessors and the necessary circuitry for
their operation. The anti-lock brake control module monitors system operation during normal driving as well as during anti-lock braking.
Anti-lock brake module operation is as follows:
^
Under normal driving conditions, the microprocessor produces short test pulses to the solenoid valves that check the electrical system without any
mechanical reaction.
^
Impending wheel lock conditions trigger signals from the anti-lock brake control module that open and close the appropriate solenoid valves. This
results in moderate pulsations in the brake pedal.
During normal braking, the brake pedal feel will be identical to a standard brake system.
Most faults which occur to the anti-lock brake system will be stored as a Diagnostic Trouble Code (DTC) in the keep-alive memory of the anti-lock
brake control module. The DTCs can be retrieved by following the on-board diagnostic procedures.
