I can't figure out what the code is for. I have been unable to find the service plug to use the method of shorting the service plug and counting the check engine light flashes. (I have checked everywhere on the passenger side of the engine bay, along the fire wall. It's not there.) I have counted the ECU light flashes from the ECU under the passenger side carpet. I get one flash, then a long pause, followed by 10 flashes with short pauses. Any help would be appreciated.
