1999 TOYOTA CAMRY radiator sensor

ABS (TMMK MADE)
This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left front
wheel and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock. This results in improved
directional stability and steerability during panic braking.
1. INPUT SIGNALS
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS actuator and ECU.
(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS actuator and ECU when the brake pedal is depressed.
2. SYSTEM OPERATION
During sudden braking the ABS actuator and ECU has signals input from each sensor, which controls the current to the
solenoid inside the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. The pump
inside the actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder, thus
preventing locking of the vehicle wheels.
If the ABS actuator and ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current on the
solenoid is controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled by the
ABS actuator and ECU, by the same method as above. Pressure reduction, holding and increase are repeated to maintain
vehicle stability and to improve steerability during sudden braking.
