Code result
P068A
ECM or PCM Power Relay De-Energized Performance Too Early
Moderate severity
What it means
The main power relay drops out earlier than the calibrated post-run window allows. The ECU loses power before completing housekeeping (e.g. saving adaptions, parking the throttle), which causes adaptive learning to reset.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
