pasadena_commut replied to the thread More MFD state of car display strangeness.

Been experimenting with that. "Hard enough" is harder than I normally step on the brakes for any stopped car. It isn't "stand on the...

pasadena_commut replied to the thread More MFD state of car display strangeness.

Seems counter intuitive to me. The car came to a stop with 3 psi on the brake pedal but once stopped (so no more KE to burn off) it now...

pasadena_commut replied to the thread check engine light + soft whirring noise.

pasadena_commut replied to the thread check engine light + soft whirring noise.

This sounds more and more hinky. Either they swapped the inverter pump and are covering their nether regions or they swapped the 3 way...

pasadena_commut replied to the thread check engine light + soft whirring noise.

Is the check engine light still off? Under normal circumstances that would indicate that they had fixed the problem. Unfortunately the...

The checksum is the easiest way to verify that the EEPROM (or whatever technology they use) has not suffered a problem, not just at but...
