How to Reset the Drive Cycle for a 2001 Ford F 150

The drive cycle is a process where the vehicle is driven from a cold start and operated for a specific period of time, and at certain speeds, in order to allow the powertrain control module, or PCM, to perform certain diagnostic procedures and gather performance data. In order to reset the process and start from the beginning of the drive cycle, a number of steps must be completed. Failure to follow the specific procedure for resetting the drive cycle can delay the programming and configuration of certain modules, as well as alter previously gathered diagnostic data.

Instructions

1

Fill the fuel tank at least 15 percent full, but no more than 85 percent full. Having the tank too low or completely full will prevent the PCM from properly completing the drive cycle.

2

Park the vehicle and turn off the engine. Turn the ignition on and connect a scan tool to the vehicle. Clear any existing diagnostic trouble codes from the PCMs memory.

3

Turn the ignition completely off and allow the vehicle to cool for at least eight hours. The engine and the vehicle must be at room temperature to ensure a cold start at the beginning of the drive cycle. This can take up to eight hours.

4

Start the engine and confirm that the malfunction indicator lamp, or MIL, is not illuminated. Immediately turn off all accessories, such as the air conditioner and blower fan. The vehicle is now ready to begin a fresh OBD-II drive cycle.
