Maxima SE V6-3.5L (VQ35) (2002)
Electronic Brake Control Module: Description and Operation
TCS
CONTROL UNIT
ABS Function
The control unit computes the wheel rotating speed by the signal current sent from the sensor. Then it supplies a DC current to the actuator solenoid
valve. It also controls ON-OFF operation of the valve relay and motor relay. If any electrical malfunction should be detected in the system, the
warning lamp is turned on. In this condition, the ABS will be deactivated, and the vehicle's brake system reverts to normal operation.
TCS Function
Drive wheel slippage is detected by the 4-wheel rotating speed signal. When the wheel slip becomes excessive, the TCS operates, causing the SLIP
indicator lamp to flash. And, at the same time, fuel-cut and throttle opening signals are sent to the ECM and a signal requiring a change in the shift
schedule is sent to the ECM. When the TCS OFF switch is used to cancel TCS function, the TCS OFF indicator lamp will light. (TCS does not
activate.) In case of a malfunction in the TCS, both the SLIP indicator lamp and the TCS OFF indicator lamp will light, while shutting down the TCS
system operation. The vehicle will operate in the same way as a vehicle not equipped with the TCS.
