BOSCH ABS 5.7

The ABS 5.7, fitted to all Rover 75 and ZT models including Tourers, also the SV series, is an evolution of the 5.3 with a smaller and lighter valve block to which the ECU is attached. Although the main job of this system is to keep the brakes from completely stopping the rotation of the wheels, allowing the driver maximum braking efficiency to stop in the shortest distance and still keep proper steering control, It also has the capability to provide traction control functionality. In the case of the diesel (M47) this is achieved by the ABS 5.7 ECU communicating directly with the engine management to reduce power, however on the V6 models this communication with the EMS is supplemented by an additional ECU which controls a secondary butterfly flap in the intake manifold being added. The ABS 5.7 although similar in appearance should not be confused with the DSC 5.7 ECU the main difference being that this system provides traction control functionality by sensing wheel speed differentials with the addition of traction control capability. The DSC5.7 provides stability control by interfacing with a multitude of sensors, its control also extending to ABS functionality.

Please Note: The ABS 5.7 ECU will not engage in diagnostic communication while the vehicle is moving. The ECU will exit the diagnostic mode whenever the vehicle speed exceeds 14 km/h (8.6 mph). The communication will be restored again when the speed falls below 14 km/h (8.6 mph).
