Inspection Procedure
Inspection Method
Drive at 6.25 mph (10 km/h), depress the accelerator pedal by 1/2 to 3/4 and keep it in that position. Under these conditions, if the engine speed decreases to 1000 rpm when the brake pedal is depressed, then the brake override system has been activated.
When carrying out the inspection, use a place where you are able to carry it out safely and also pay close attention to your surroundings.
Also, when driving make absolutely sure that all road traffic laws, such as speed limits, are observed.
HINT:
- Under normal conditions, the Accelerator Position value changes in response to the Accel Sens. No. 1 Volt % value. For more information on the numerical values, refer to the Data List. Refer to DATA LIST / ACTIVE TEST .
- If the Data List values of Accelerator Position and Accel Sens. No. 1 Volt % do not match, and the value of Accelerator Position changes but the value of Accel Sens. No. 1 Volt % is constant, this confirms that brake override system has activated. (Data can be captured relatively easily by using the snapshot function in the Data List. Confirm the data after performing the drive 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 loss of torque after the accelerator and brake pedals have both been intentionally depressed, explain to the customer that this is not a malfunction, and that the customer should avoid depressing both the accelerator and brake pedals at the same time.
Example: While operating the accelerator pedal, the customer uses their left foot to operate the brake pedal.
