2000 Chrysler with 214000 miles developed a P0171 code that won't clear using the incardoc device. Car had been running great and just suddenly started missing badly then died. Wait a few minutes and it will restart and run for a few minutes. Next day no problems except the 171 code won't clear.
Please also note, that it's recommended to clear codes with stopped engine but full power on ECU
key ON (or II) position
- stop car's engine and switch key to ON (or II) position
- plug in adapter, check that it's powered
- connect from the app
- open Diagnostic page and wait finishing of reading
- use Clear button to clear the codes from ECU's memory
Please also note to clear errors only after fixing appropriate car's malfunctions, other case car will automatically rise errors again with the next self-test cycle.
