Brake Override System (From GH1***-442043, GH10**-210449)

Operation of brake override system

•  The brake override system gives priority to the brake operation if a malfunction occurs with the accelerator pedal such as if the accelerator pedal is depressed and does not return. The fuel injection amount is controlled if the brake pedal is depressed while the accelerator pedal is in a depressed condition until the vehicle is safely decelerated and comes to a complete stop.

Brake override operation conditions

•  If either one of the following conditions is met with the brake pedal depressed for 1 s or more while the accelerator pedal is depressed, the PCM controls the fuel injection amount so that the engine speed is the specification*. While driving vehicle ―  Accelerator pedal opening angle: 5 % or more from fully-closed ―  Vehicle speed: 10 km/h {6.2 mph} or more ―  In gear ―  Engine speed: 1,150 rpm or more While vehicle stopped ―  Accelerator pedal opening angle: 5 % or more from fully-closed ―  Shift lever position: neutral ―  Engine speed: 1,150 rpm or more

End brake override operation

•  If the following conditions are met while operating the brake override system, the PCM stops the operation of the brake override system and controls the throttle valve opening angle in accordance with the fuel injection amount. ―  Accelerator pedal is not depressed ―  Brake pedal is not depressed Note •  Cycling the key off and back on will also end brake override operation.

Disabling of brake override system

•  If the servicing procedure requiring the brake pedal and the accelerator pedal to be depressed together, operation of the brake override system can be prevented, if necessary.

Disable brake override operation conditions	•  If the following conditions are met for 10 s within 30 s after switching the ignition ON (engine off), the brake override system is disabled until the activate brake override operation conditions are met. ―  Shift lever position: neutral ―  Vehicle speed: 0 km/h {0 mph} ―  Accelerator pedal fully depressed ―  Brake pedal depressed
Activate brake override operation conditions	•  Cycling the key off and back on will activate the brake override operation conditions.

Brake system warning light illumination request

•  If the following conditions are met, the PCM sends the brake system warning light illumination request signal to the instrument cluster. The brake system warning light illuminates to alert the driver that there is a malfunction in the brake system.

―  Malfunction in brake switch No.1 and 2 or both is detected
