Trunk and engine hood "locked" with good battery and working r

[Hanseman]

Dear Renntech forum,

 

It seems that the alarm module have had a partial mishap and does not disengage the hood/trunk latch lock upon remote key operation. Neither does manual entry work. The car starts fine, locks/opens all doors with window operation intact, and I have checked all fuses. I have tried to recycle the remote but that did not solve the issue either. 

 

The only thing that may coincides with this error is a extraordinary quick "airbag light" that came on instantly after I reset it (using Durametric). 

 

Could it be the electrics under the driver seat, such as the ground cable? I am reluctant to go there because it is with some concerns that I would work in that area without disconnecting the battery (I have the hood latch override cable available though).

 

Any suggestions are good suggestions!

 

Best regards,

 

Hans

If it is only the lock mechanisms then it is likely the central locking/alarm control under the drivers seat.

Any chance it got wet? If so, you may have a lot of work ahead of you.

Dear Loren,

 

No, no water at all. 

 

Durametric says 46 "control locking synchronization" Status: present

 

Any way to resynchronize the latch with the door. I am thinking to use the manual release for the hood and disconnect the battery....

 

Best regards,

Fault code 46 -- Central locking synchronisation

 

Possible cause of fault

- Short circuit to ground/open circuit between alarm system control module and door locks

- Door lock faulty

I opened the trunk using the manual release cable, and disconnected the battery (more than 10min). While without battery connected, I removed the driver-side seat and used contact cleaner to remove any oxide on the alarm module ground cable. After reassembly and battery connection, I can still not use the levers for front/engine hoods as the latch remains engaged. Car starts fine, locks operate, and fuel door locks/unlocks. 

 

I suppose next step is to disassemble the driver side lever assembly to make sure the latch solenoid is OK!?!? 

 

Any suggestions?

 

Best regards,

 

Hans

Dear Renntech forum,

 

Ok, so I did access the driver-side lever assembly to inspect the latch solenoid. The wire that moves back and forth to bring the plate to locking position moves smoothly. The solenoid does not move when I engage the remote lock (flipping the black door mechanism to close) - in either way to lock (from open) or to open (from lock). I assume that the solenoid is bust (or the wiring does not deliver the appropriate signal). Either way, it is not intuitive how to access it for removal/testing? Is it the two Philips head screws only that hold the whole side mounting bracket? 

 

Could there be any other explanation for the solenoid not moving? Everything else reacts to the remote lock as it should. 

 

Comments and suggestions, please!

 

Thank you,

 

Hans
