[QUOTE="SecondhandSnake, post: 13008793, member: 116684"] I would look closer at your CCRM harness and grounds. That's exactly what mine did when I had a bad CCRM ground. Buzzing (relay fluttering due to bad ground) from the CCRM, and PATS was activated and there was no odometer reading because without the relay closed in the CCRM, the PCM doesn't get power, thus it doesn't communicate with PATS or show your mileage. EDIT: Just noticed you're in Lancaster. Friendly hello from someone who grew up the next town over and actually bought this car off a guy in Lancaster. [/QUOTE]
