Toyota RAV4 Service Manual: Fail-safe chart
- Fail safe operation
- If there is a problem with any sensor signals or
actuator systems, the skid control ecu prohibits the
power supply to the abs and traction actuator
and informs the ecm of vsc system failure.
The abs and traction actuator turns off the solenoids and the ecm shuts off vsc control (traction control signal) from the skid control ecu accordingly, the result being that it is as if the abs, trc and vsc systems were not installed.
- Abs control is prohibited, but ebd control continues as far as possible. If ebd control is impossible, the brake warning light comes on to warn the driver (see page bc-44).
- If system components have any malfunctions before
starting control, the operation stops immediately. If
system components have any malfunctions during
control, the control stops gradually so as not to trigger
a sudden change in vehicle conditions.
If it is impossible to control the systems, the warning light comes on to inform the driver of malfunctions in the systems (see page bc-44).
Hint:
- If the abs system malfunctions, the brake system operates normally without the abs system.
- If the brake actuator malfunctions, a gradual loss of brake performance is expected, and abs system control is prohibited.

Freeze frame data
Hint:
Whenever a dtc is detected or the abs operates,
the skid control ecu stores the current vehicle
(sensor) state as freeze frame data.
