TCS Function
Drive wheel slippage is determined by comparing speed signals from all 4 wheels. When the wheel slip becomes excessive, the TCS operates, causing the SLIP indicator lamp to flash. At the same time, a signal requesting a change in the shift schedule will be sent to the TCM (with A/T) and a fuel-cut signal is sent to the ECM. When the TCS ON/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 TCS.
