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
