Anybody know what these codes mean
 

I recently have had issues with my rear hatch unlocking when I open the drivers door or remove the key after turning off the car. I've even had it unlock when stopped at a light or shutting the lights off. So went to my friends shop and clean the lower truck latch and took the handle off the tailgate/hatch and found the plug that connects to the handle assembly green and corroded. Of course it got cleaned up.It still unlocks when not asked to. So I went into the owners manual a reset the settings for what happens when the remote unlocks the doors and locks them when the car starts to move. Of course tried using the other key set. none of all that helped. So I put the scanner on it and looked for codes. The following codes were found: 2FD7 EWS ANTI THEFT TAMPERING PROTECTION. 287D VANOS INLET VANE ACTUATOR. 2A56 OXYGEN SENSOR HEATING AFTER CAT FUNCTION. 276A CATALYTIC CONVERTER CONVERTION. I'm really not concerned about the CAT and o2 codes since the car has an AEM RAM AIR INTAKE SYSTEM and a hi-flow cat with no tune. YET !!!

2008 S Model. 2 door hardtop n14 R56

Also just food for thought, is there a ground the could need the be cleaned ? How about a blown fuse for some odd reason ? Didn't check fuses yet. I even thought could something be wrong with the BC1 module ? (Body control)

This car also has 153,000 miles

I'd guess the anti theft is causing the lock/unlocking issues might be there is corrosion on door switches or the hatch cleanups not perfect

Have you tested the battery ? at times I've seen lower voltage cause weird "random" troubles. Also have you cleaned/checked battery terminals ?

what about the other codes ? what do they mean ? mitchell ondemand at the shop does not have the same code prefixes

my manuals not showing the same either I was assuming it was the reader you are using. Some need conversion to proper codes ...

I'll Ask again have you checked battery (voltage and load test) and terminals?
So often the battery gets weak and the computer freaks out

actually the battery is brand new

Hey, sorry to wake this thread up but did you figure this out?

in my case, i found was water damage to the circuit that was shorting out the button. After replacement, it never failed again.
