I'm trying to diagnose a p0171 error code.
I've got an actr1. install the scan tool
- start and idle engine at normal operating temperature in the Closed Loop
- record the data for long term fuel trim
- turn off engine
- turn on ignition, engine off
- review freeze frame / failure records and record displayed data for this diagnostic trouble code
how do I get it in the Closed Loop? how do I get the data for long term fuel trim in the scanner? how do I view freeze frame / failure records in the scanner?
thanks.
