Revised Title to include Repair Group
• Customer states that the engine returns to idle speed of approximately 1,400 RPM although the accelerator is
depressed, and/or the vehicle hesitates (lacks power on take-off).
• No DTCs are stored.
Technical Background
This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously.
Drivers who drive with their left foot resting on the brake pedal are prone to experience this condition.
With the introduction of Electronic Power Control (EPC) (no accelerator cable) to fuel injection systems, an engine
RPM control feature has been incorporated into the engine electronic control system software. As a result,
application of the brake and accelerator pedals at the same time (brake pedal with left foot and accelerator pedal
with right foot) results in the following:
• Brake pedal function (normal at all times) overrides any throttle application.
• Diagnostic Trouble Codes (DTCs) will not be stored.
• When the brake pedal is applied while the accelerator is depressed, engine RPMs will return to idle speeds of
1400 RPMs after approximately two seconds.

Technical Service Bulletin
• When the accelerator is applied while the brake pedal is depressed, the vehicle accelerates slower than usual
(reduced engine torque).
Production Solution
Not applicable.
Service
1. Test drive vehicle with customer to duplicate the condition.
2. During test drive, observe customer’s driving habits to determine if customer drives and/or brakes with his/her
left foot.
3. After test drive with customer, connect a VAS diagnostic tool and check for any stored DTCs.
• If DTCs are found, repair as necessary.
• If no DTCs are found, explain the previously listed technical correlation between brake pedal and
accelerator functionality to the customer:
- Brake pedal overrides the accelerator pedal application at all times.
- It is best not to drive with the left foot resting on the brake pedal.
