Hi,
this car came to me with problem that sometimes the remote control doesn´t work, but when I tried it, it works perfectly. The problem/strange thing is the driver door/key lock - it locks the car, but not unlocks (just switch the interior light on and when I stay in unlock position, windows go down, but all doors are still safe), respectivelly not unlocks just from safe (when the ignition is switched on, it locks by the key just to locked/not safe position and the key also unlocks all doors). I´ve tried to find something in coding/adaptation (found just things like confirmation methods or if the windows works by key or remote, etc.), but have no clue what causes this strange behavior (all microswitches seems to be ok).
:banghead:
Any ideas, please?
Thanks

Strange, the key in the door lock should mechanically unlock, as well as send the disarm signal on the comfort data bus. And since you stated the windows roll down when the key is turned to unlock, you can assume that the microswitch in the lock module is infact working correctly and the rest of the system is responding by at least rolling the windows down.

When you turn the key to unlock twice, do all the doors unlock, or none?

Even twice doesn´t unlock (from safe). Yes, it is strange, I am thinking about some terminal logic or some "safety" functions, but found nothing yet...

^^^^ hmm..... agree with deiseldub - very odd indeed. I wonder whether the parallel parking DTC in your auto-scan might be implicated -perhaps?

Yes, T15 voltage should not be present when the unlock function is activated in your example, but perhaps the CAN network thinks that there is a problem with the way that it parked the car and therefore it doesn't want to open the driver's door. If you clear this DTC -is there any correlation between the next occurrence of the error and using parallel park at the previous ignition cycle and subsequent strange lock behavior?

Long-shot I agree, but in the absence of a better suggestion - perhaps worthy of consideration?
