Electronic Brake Control Module: Description and Operation
Kelsey-Hayes EBC Controller Antilock Brake (CAB)
The CAB is mounted under the hood, separately from the valve body, and has a microprocessor and circuits that:
-
monitor the brake switch input to tell whether or not to prepare for possible antilock braking
-
monitor the wheel speed sensor inputs to determine when a rear wheel is tending to lock up.
-
operate the integral control unit assembly during antilock braking based on comparing the speed sensor to information programmed in memory
-
detect ABS system related problems and take diagnostic action
The CAB will disable antilock control and set a hard ignition latched trouble code if it detects one of the following conditions with itself:
-
(71) RAM Read/Write
-
(72) ROM Checksum
-
(73) Watchdog
