Inspection Procedure
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
Inspection Method
Drive at 10 km/h (6.25 mph), depress the accelerator pedal by 1/2 to 3/4 and keep it in that position. Under these conditions, if driving torque is controlled when the brake pedal is depressed by the left foot of the driver, it can be confirmed that the brake override system has operated.
WARNING:
Perform this road test only in an appropriate safe location, in accordance with all local laws.
Pay careful attention to the surroundings when performing the road test.
HINT:
- Under normal conditions, the Accelerator Degree value changes in response to the Accel Pedal Pos #1 value.
- If the Data List values of Accelerator Degree and Accel Pedal Pos #1 do not match, and the value of Accel Pedal Pos #1 changes but the value of Accelerator Degree is constant, this confirms that the brake override system has operated. (Data can be captured relatively easily by using the snapshot function in Data List. Confirm the data after performing the road test.)
- The brake override system restricts driving torque if the brake pedal is depressed when driving with the accelerator pedal depressed. If a customer reports experiencing a loss of power (driving torque) after the accelerator and brake pedals have both been intentionally depressed, explain that this is not a malfunction, and depressing both the accelerator and brake pedals at the same time should be avoided.
