Toyota CH-R Service Manual: Fail-safe Chart

• If there is a problem with sensor signals or actuator systems, the skid control ECU prohibits power supply to the brake actuator assembly and informs the ECM of a VSC system malfunction.

  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, VSC and brake hold 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 system warning light (red indicator) will come on to warn the driver.

• If a VSC system component malfunctions before VSC control begins, VSC control will be prohibited. 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.

• When a malfunction occurs in the VSC system or electric parking brake system, brake hold control prohibits brake hold operation to prevent incorrect operation and protect the system.

  HINT:

  When control is prohibited, the brake hold operated indicator light blinks, and the code for the system where the malfunction occurred during diagnostic mode is displayed by the brake hold standby indicator light.
