FAIL-SAFE CHART
The brake actuator assembly turns off the solenoids and the ECM stops its VSC control according to signals from the skid control ECU. The vehicle will operate in a manner similar to a vehicle that is not equipped with ABS, TRAC and VSC systems.
ABS control will be prohibited, but EBD control will continue to the extent that EBD control is possible. If EBD control is impossible, the brake warning light will come on to warn the driver (See page ).
If a system component malfunctions during VSC control, the system will gradually stop performing control so as not to trigger a sudden change in vehicle operation.
If it is impossible for control to continue, the warning light comes on to inform the driver of system control termination (See page ).

Steering Angle Sensor Initialization Incomplete (C1439,C1445)
DESCRIPTION
The skid control ECU (brake actuator assembly) acquires steering angle sensor
zero point every time the ignition switch is turned ON and the vehicle is driven
at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores the
previous zero point.
The steering angle ...
Transmitter ID not Received in Main Mode (C2126/26)
DESCRIPTION
After all transmitter IDs are registered, DTC C2126/26 is stored in the tire
pressure warning ECU and receiver and the tire pressure warning light blinks for
1 minute and then illuminates.
When the tire pressure warning ECU and receiver successfully receives radio waves
from all ...
Evaporator Temperature Sensor Circuit (B1413/13)
DESCRIPTION
The cooler thermistor sensor (evaporator temperature sensor) is installed on
the evaporator in the air conditioner unit to detect the temperature of the cooled
air that has passed through the evaporator and is used to control the air conditioning.
It sends signals to the air condi ...
