Complaint: Customer describes lack of power or poor acceleration.
Solution: Perform the following checks before attempting any repair:
• Check for stored DTCs.
• Check if the driver is resting his left foot on the brake pedal while accelerating. Advise the customer not to rest his foot on the brake while accelerating.
• Use a scan tool to check operation of the brake lamp circuit signal. Monitor the brake switch during the incident; it should be “OFF.”
Causes of brake switch “ON:”
• Brake switch incorrectly adjusted (switch is adjusted ON when it should be OFF).
• Damaged brake lamp wiring/circuit (damage causes signal to ECU to show ON when it should be OFF).
Note: Refer to the service information for correct brake switch adjustment and/or circuit diagnosis as applicable.
