DETECTION CONDITION

•  A condition is detected in which the brake pedal is depressed ^* while the vehicle is driven under the following conditions.

Vehicle is being driven

―  Other than idling

―  Engine speed: 875 rpm or more

^*: The brake override system may not operate depending on the brake pedal depression amount.

Diagnostic support note

•  This is a continuous monitor (other).

•  The check engine light does not illuminate.

•  FREEZE FRAME DATA/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  Controls the throttle valve so that the engine speed is at 1,000 rpm. (Brake override system)

POSSIBLE CAUSE

Note

•  If the brake override system operates, the PCM detects DTC P2299:00.

•  Driver is depressing accelerator pedal and brake pedal simultaneously (such as depressing brake pedal with left foot)

•  Accelerator pedal is pressed in condition such as by floor mat

•  Accelerator pedal stuck

•  Accelerator pedal position sensor signal malfunction

―  Accelerator pedal position sensor malfunction

―  Accelerator pedal position sensor-related wiring harness, connector malfunction

•  Brake switch signal error

―  Brake switch malfunction

―  Brake switch-related wiring harness, connector malfunction

―  Brake pedal malfunction (increased looseness due to joint pin wear)

•  PCM malfunction
