Hey!

I have a -99 P38 DSE

Today morning i noticed the car had locked the doors by itself.
Tried opening with remote, nothing happened.
Opened manually with the key, and the door locks it self back.

I quickly jerked the door open and got in, and the car is totally mute.
Instrument panel does no light up at all, alarm light is flashing, beeps when key is inserted and stops when key is turned to position 2.
And a slight ticking sound under right front seat.

I disconnected the battery and tried again little later, and got the same results.
I had to leave to work and left the car with the battery disconnected.

I need some advice, is the BeCM locked now or what might be the problem?
Got the car couple of moths ago.

Sounds like an almost flat battery. They do strange things as the battery volts drop below about 12.4 volts
 
I'd agree on the battery. Even if it charges to 12v and over have it checked for it's health and capacity. If already a good healthy battery then a possible battery drain situation could be causing issues. Have the battery checked for capacity and go from there👍
 
Alright, hope its only that.
i'll pick up a new battery on my way home, since current one seems old.

I was thinking about disconnecting the RF receiver.
What i read its a common problem with draining batteries.
The lock motor on passenger door doesn't work anyways so i have to lock the doors manually.
 
Ended up being just a dead battery, hehe...
Had to run back and forth because the first battery i got had the terminals on opposite sides...

Also my neighbor had noticed that my interior lights were on last night.
Might have something to do with the faulty locks, i'll have to look into that next..

Interior lights may have come on as the battery went flat due to the BECM losing control.
Hope you charged the new battery before fitting it.
