Inspection and Verification

  1. Verify the customer's concern by operating the acceleration control system to duplicate the condition.
  2. Inspect to determine if any of the following mechanical concerns apply:

    Visual Inspection Chart 

    Mechanical 

    • Damaged accelerator pedal and shaft
    • Damaged linkage
    • Damaged acclerator cable
    • High engine idle speed
    • Damaged throttle body
    • Damaged or binding adjustable pedal assembly
  3. If the inspection reveals an obvious concern that can be readily identified, repair it as required.

    All vehicles are equipped with adjustable pedals. This allows both the accelerator and brake pedals to be adjusted simultaneously forward or rearward. A rocker switch on the instrument panel provides adjustment on the pedal's assembly when it is activated. On vehicles with the memory seat option, the pedal's position can be controlled by the memory selection, as well as the rocker switch. The accelerator pedal can be serviced separately from the brake pedal. The components in the acceleration control system are not adjustable and new components must be installed if damaged or worn.

  4. If the concern remains after the inspection, determine the symptom(s). GO to SYMPTOM CHART .
