So I had removed the fuse under hood to disable DRL when I first bought car about 1.5 yrs ago with 56k mi. I noticed a few times when I hit lock or un lock on the key fob sometimes not always, doors would not lock or un lock on the 1st try, also notice after letting car sit in garage for a few days or so I would always get the error code c1214.

so a few months ago I noticed a post here how to disable drl and keep the reverse lights lighting up think its called approach lights? while also disabling the drl, so I pulled relays on passenger side floor cut and put in small pieces of an expired credit card and all was good and working how I wanted.

What I have noticed is since then each time I press lock or unlock button on key fob doors always lock or unlock 1st time I know because I have gotten in the habit of always checking if they lock, I have never gotten any errors like c1214 for the ebcm or anything else. Alls working great for the past few months.

Only other thing I did to the car when I changed how I disable drl was send temp display in for rebuild because of a dim display I was told I had 3 bad resistors in temp display unit and they were replaced.

Car is my daily driver and prior to replacing drl fuse and having temp display fixed I would notice at least once a week the doors would not lock on 1st attempt also if car sat for a day or so would always get the service traction control or c1214 error which would then go away after driving car for 5 min.

Just wondering if this is possible? Yesterday I removed ground connectors under hood and cleaned although were not that dirty at all. But wanted to be sure grounds were clean.

Not sure this is a fix but my want to try if anyone having any of the issues I have had in the past?
