Fail-safe Function

• When the malfunction detection function determines a malfunction, each light illuminates to advise the driver. At this time, the fail-safe function controls the ABS, EBD and TCS* as shown in the fail-safe function malfunction contents table.

*: Only vehicles with TCS

Warning
• If EBD control is suspended the rear wheels could lock-up before the front wheels. If this occurs, the vehicle could swerve and become unstable. Therefore always inspect the system immediately if EBD control is suspended.

*1:
With TCS
*2:
If a malfunction was detected in the previous driving mode, the light remains illuminated until the system is verified to be normal when the vehicle is driven at a speed of 10 km/h {6.2 mph} or more.
*3:
The warning light does not illuminate during a front solenoid valve OFF malfunction (Inlet solenoid valve is stuck open; Outlet solenoid valve is stuck closed).
*4:
Control continues only during a front solenoid valve OFF malfunction (Inlet solenoid valve is stuck open; Outlet solenoid valve is stuck closed).
*5:
Illuminates during rear wheel malfunction.
*6:
Suspends control when there is malfunction in both rear wheels.
*7:
The light will go out when the failure is solved.
*8:
When engine coolant temperature is 0 °C {32 °F} or less, and TCS operation is inhibited by PCM. DTC is not stored. When engine coolant temperature rises and TCS OFF light goes out, the system is normal.
