Passenger Door Won't open. Immobiliser control unit central locking system alarm system


Recommended Posts

if i replace the theft control unit Parts # 99661826007 on my 99 Porsche Carrera do i need to reprogram the keys. i'm kinda confused because the transponder in the ignition cylinder has nothing to do with CLU. does anybody have a schematic diagram of the Central Locking Unit this way i can figure out what causes this freakin' problem. there must be a simple way to fix this $20 is the most instead of spending $400-$600 to replace. i asked because only the driver side open and the passenger side doesn't. it all happened when i forget to disconnect the battery before i remove the airbag connector and replace the door microswitch on the passenger side. luckily, i haven't put the door panel back. i also replaced the ignition switch thinking that it will fix the problem. whoever the previous owner of this car did some stupid thing by drilling a hole on the door latch and inherited the problem. below are the codes showing on my Autel MD802. 
 

Auto Scan: Alarm System Fault | 8.
Fault Memory:
47 Control Locking Syncronization (pointing to key and the CLU) 
25 Terminal 86 S not Detected (Fuse OK)
61 Central Locking limit position Unlock not reached. (Pointing to CLU box under the driver side)

please advice. thanks.

Fault 25 - start by checking fuse E1. (4th row down and first fuse on the left.

 

In my experience fault 47 (with fault 61) is usually caused by a mechanical failure in one of the door locks.

You can tell which one using a Durametric or Porsche PIWIS tester. You can also test the microswitches in the door(s) using these diagnostic tools.
