Hey Guys,

I've been having some electrical issues and I'm starting to think that they might revolve around this issue. In the last 4 years i've had to go through probably 6 batteries. They don't loose charge, but start acting strange. It's almost like intermittent power loss, 1 second its low on power and 1 second it's fine. I think this is causing my BCM to go crazy and throw lots of random codes on my DIC, but these codes have always been constant and i believe my issue might be different than the "usual" case.

Back to the battery, every time I suspect a problem i go to my local auto store and get my batter checked. Almost every time they say "yup, you've got a bad battery" and they give me a new one for free (because of my warranty on the battery).

I'm thinking that these codes might be whats causing it.

I've done a bit of research on these and it seems that they are related to the memory setting. My problem is... I do not have the memory buttons on my door panel controls. I've seen them before (the 1 & 2 above or below the mirror position buttons) however my car does not have these. I'm thinking the previous owner must have replaced something on the car that wasn't supposed to be on this model. Now the car has these codes 100% of the time and i'm thinking that the car getting this error 100% of the time, or the wrong part being hooked up is causing these electrical issues.

Here are the codes i have,

B2262 Horizontal Position Sensor Fit DCM-L
B2264 Vertical Position Sensor Fault DCM-L

B2263 Horizontal Position Sensor Fit DCM-R
B2265 Horizontal Position Sensor Fault DCM-R

I've read that these codes will only be removed once the correct voltage is sent to their sensors.

Any thoughts of what to look at, or if i'm even thinking in the right track would be great!

Also, here are some of the other random codes i've been getting, just in case it will help.

B2578 RF Turn Signal Monitor Circuit (Short to Voltage)
B2583 LF Turn Signal Monitor Circuit (Short to Voltage)

Also a bunch of random U codes...

U1016 Loss of Communications with PCM
U1040 Loss of Communication with TCS
U1056 Loss of Communications with RTD
U1064 Lose of Communications with DCM

thanks for any help!

EDIT: Btw, my mirrors do work perfectly, and at 1 point my turn signal was burned out, but my DRL's and turn signals have worked fine since. (still getting the code randomly though)

 

The batteries have bad cells?

That's what they have told me. I could see that happening once or twice, but this many times? and this soon on brand new batteries?...

I'm posting now because I had the battery checked this weekend after i noticed my headlights dimming an unusual amount from rolling up & down the windows.

I have been plagued by the steering column lock for over a year. Doing fix after fix, and i'm starting to think the issues aren't really with the steering column, but a glitch somewhere in the electrical system.

If you guys have any further questions... Ask away!

 

My thinking is that all those batteries were not defective. Have you checked all the ground locations to make sure that they are tight and corrosion free?

 

Just a thought, have you checked the ignition switch? All power to the modules go through the switch.
