2017 Explorer Code P608A

[SWEET ST]

Explorer would not start had to call AAA gave booster car started but check engine light came on with code P608A what does it means. I read P068A - ECM/PCM Power Relay De-Energized Performance - Too Early Possible causes Faulty Engine Control Module (ECM) relay Faulty ECM ECM harness is open or shorted ECM circuit poor electrical connection. what would it means. Please advise.

This sounds like a nuisance code brought about due to the low voltage situation of the battery that had to be jumped. If it were me, I'd clear the code and/or wait for the light to turn off after a few drive cycles.

Thank you. I feel same. I reset the code. I also let car run for about 1hr and restarted few time and all is well.
Some cars even when i reset code it still stays in system does this happens with explorer ? will it come back ?

It really shouldn't come back unless the fault is truly there. If you don't see it after a week or so, write it off.

An easy way to see if your car's completed the OBD Drive Cycle is to go into ignition on/engine off and wait about 20 seconds keeping focused on the Check Engine light. If it flashes with the engine off, the OBD monitors are still running and validating, if it stays solid, you're in the clear and the monitors have all been validated and you shouldn't have to worry about stored codes (at least for inspection purposes.)

Will do that. Thank you !
