Description

If a malfunction is detected in the power supply circuit of the brake actuator assembly (skid control ECU), the skid control ECU (housed in the actuator assembly) outputs the DTC and prohibits operation with the fail-safe function. This DTC is output when the IG1 terminal voltage deviates from the DTC detecting condition due to a malfunction in the power supply or charging circuit such as the battery or alternator circuit, etc. This DTC is cancelled when the IG1 terminal voltage returns to...

If a DTC of the motor line is stored, the VSC No. 2 relay cuts off the power supply to the VSC No. 1 relay and performs fail-safe. While any of the ABS, TRAC, VSC, or BA is operating, the skid control ECU (housed in the ABS & TRACTION actuator assembly) turns the VSC No. 2 relay on and activates the pump motor in the ABS & TRACTION actuator. This code may be stored if the motor relay (+BM) voltage becomes lower than the DTC detecting condition due to insufficient output from the battery...

Failsafe Chart

If there is a problem with sensor signals or brake actuator systems, the skid control ECU will prohibit power supply to the brake actuator and terminate ABS control. ABS control will be prohibited, but EBD control continues as much as possible. If EBD control is impossible, the brake warning light will come on to warn the driver (See page BC-17). If the ABS system has a malfunction, the brake system will operate normally without ABS control.

Freeze Frame Data

Whenever a DTC is detected or the ABS operates, the skid control ECU stores the current vehicle (sensor) status as freeze frame data. The skid control ECU stores the number of times (maximum 31) the ignition switch has been turned from off to the on (IG) since the last time the ABS was activated. Freeze frame data at the time the ABS operates The skid control ECU stores and updates data whenever the ABS system operates. When the skid control ECU stores data at the time a DTC is detected, the...

Diagnosis System

(a) If the skid control ECU detects a malfunction, the ABS, BRAKE, VSC warning lights and SLIP indicator light will come on to warn the driver. The table below indicates which lights will come on when there is a malfunction in a particular function. The DTCs are simultaneously stored in the memory. The DTCs can be read by connecting the SST between terminals TC and CG of the DLC3 and observing the blinking of the ABS and VSC warning lights, or by connecting the intelligent tester. This system...
