Mustang Cobra V8-281 4.6L DOHC VIN V MFI (1997)
Electronic Brake Control Module: Description and Operation
Anti-Lock Brake Warning Indicator
DESCRIPTION
The anti-lock brake control module monitors wheel speed and controls anti-lock brake system (ABS) function. It also has on-board diagnostic
(OBD) capabilities and stores diagnostic trouble codes (DTCs) in its memory.
OPERATION
When the anti-lock brake control module detects an impending wheel lock, it modulates brake pressure to the appropriate brake caliper. The
anti-lock brake control module receives wheel speed readings from each brake anti-lock sensor, and uses this information to compare wheel
speeds. By continuously monitoring and comparing the rotational speed of each wheel, the anti-lock brake control module activates the anti-lock
braking system only when it senses an impending wheel lock-up under severe braking conditions. The anti-lock brake control module decides
which brakes need to be controlled, and sends the appropriate signals to the Hydraulic Control Unit (hydraulic portion of the assembly).
Impending wheel lock conditions trigger signals from the Hydraulic Control Unit that open and close the appropriate modulator solenoid valves.
This may result in moderate pulsations in the brake pedal when applied. During normal braking (non-ABS stop), brake pedal feel will be the same
as a vehicle with a standard brake system (non-ABS).
DTCs
If a fault is detected in the system, a DTC will be stored in the anti-lock brake control module memory, and the instrument panel ANTI-LOCK
warning indicator will illuminate when the engine is running. The anti-lock brake control module has the ability to store three DTCs in memory.
