Checking The Status

Read off the movement of the accelerator pedal by carefully depressing and releasing the accelerator pedal (AP).

Check that the value for the PWM signal changes with accelerator pedal movement. The value must be between 5 % (released pedal) and a maximum of 90 % (fully depressed pedal). The function is OK if the value is within this range and follows the pedal movement.

The fault is intermittent at the moment if the values are OK.
