TCSIABS SYSTEM System Description ABS FUNCTION During ABS operation, the brake pedal pulsates along with a mechanical noise. This ensures that the ABS is working properly. mP When starting up the engine or immediately after the vehicle starts to run, the brake pedal pulsates and G' a motor noise from the engine compartment can be heard. They are caused by the ABS operation check and should not be considered abnormal. EC A vehicle with the ABS may stop in a longer distance than a vehicle without the ABS when the brake is applied on a bad road, gravel road, or deep fresh snow. TCS FUNCTION TCS/ABS control unit monitors the speed of the driving wheels through 4 wheel speed sensors. If driving wheel slip is detected, fuel to the engine is cut ol and the throttle valve is adjusted so that the engine a torque is reduced. On vehicles with automatic transmission, transmission shift schedule is also changed to control the rear wheel driving torque, which results in the reduction of wheel slip. This system enables the throttle valve to be controlled so that optimum engine torque can be achieved in accordance with the driver's acceleration request. The driver may not feel satisfied with acceleration on some road surfaces. This poor acceleration occurs because the operating TCS gives priority to maintaining optimum traction. Therefore, this condition should R8 be considered normal. When shiftdown is made or the acceleration pedal is depressed while the vehicle is driven on the road r-- 4 surface that has different friction coefficients, the TCS may operate temporarily. Lrd[-i On vehicles with manual transmission, the SLlP indicator lamp and the TCS OFF indicator lamp may light up when the engine is about to stall in the conditions shown below. If the lamps go off when engine speed increases, there is no problem in the system. At start, the engine almost stalls and the engine speed is much lower than the idle speed. The vehicle is driven at an extremely low speed with a high-speed gear engaged. 8D The clutch has been engaged until the vehicle almost stops. FAIL-SAFE FUNCTION ABS system If any malfunction is detected in the system, the ABS warning lamp, the TCS OFF indicator lamp and the SLlP indicator lamp in the instrument panel is turned on with the TCSIABS deactivated and the vehicle's brake sys- tem reverts to normal operation. TCS system If any malfunction is detected in the system, both the SLlP indicator lamp and the TCS indicator lamp on the instrument panel light up and the TCS is shut down. The vehicle operates in the same manner as a vehicle without the TCS, while the ABS is operational. If there is a malfunction in the throttle control system, the TCS becomes inoperative while the ABS remains functional. When fail-safe operation is activated, perform the self-diagnosis procedure for the TCSIABS first. Refer to BR-27 for details.
