Ford Mustang SES Light Q. I have a 2001 Ford Mustang V-6. Because of engine modifications my Service Engine Soon light stays on. Nothing really wrong with the car, it just pushes more air now than the computer says its supposed to according to the mechanics at Ford.

My question is how do I reset the light? I don't like having to take it to the Ford dealer every time it comes on, and I'm sure they are tired of seeing me. Any help you can give is appreciated!

A. Disconnecting the battery ground cable for a minimum of five minutes may be used as an alternative reset procedure to a scan tool. The following events occur when a PCM reset is performed:

• Clears the number of Diagnostic Trouble Codes (DTCs).
• Clears the DTCs.
• Clears the freeze frame data.
• Clears diagnostic monitoring test results.
• Resets status of the OBD II system monitors.

After Keep Alive RAM has been reset, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.
