faulty security module

Hi there,
Most likely when you drove over the water it caused the wirings of the alarm to go trip.
A definite fix would be to rewire the alarm using new wires as it will be hard to find where is the faulty wiring coming from.
After rewiring the alarm i'm 100% sure that everything will be just the way it was. (it happened to me once so I base it from experience)
Thanks a lot!

The problem could have been from residual static charge on the car from the polishing process or more likely the computers just needed a reset. As with most highly integrated electronic computerized equipment today (i.e. cars, airplanes, etc) when numerous electrical issues are present a hard reboot or restart usually fixes the problems.


Actually I just tried this and it seems to be working for the time being. As mentioned before if you can get the system up and running, while simultaneously holding down "Map/Guide, Menu and Cancel" for a few seconds, it does bring up some sort of test or configured menu. Within this diagnostic menu, select the "version" button and then select the button that has something to the effect of "download cd" or something like that, basically the one not involving the "pc card". It then downloaded data from the dvd I'm assuming and the system reloaded the software I'm guessing at this point. I didn't have to re-enter my radio code that I have memorized. At this point, I was able to do the things I've done in the past like using the system. I have turned the car off numerous times and the system is performing as it should at the moment. Hopefully this is the simple fix to this problem. Would like to know if it works for anyone else.

you will need to enter a code to get the radio to work again. if the code is not in the owners manual, you will probably need to call a dealership to get the code. you will probably need the vin number of the car.

My mercedes vito (model 2006) diesel wont start because of start module failure. What can i do ?

Hi

a dealer should be able to give you the code if you get the serial number from the radio, also are you sure the code is not in with your car books, service manuals and book packs, often it is in there o a small credit sized card. alternatively some radio decoders will come to you at home, they charge about £25 in the UK to recode the radio.

Hope this helps

Hi,

This car has a known fault with a relay that causes these exact symptoms. The relay is responsible for fuelling and typically develops an intermitent fault causing the vehicle to stall and then restart after a few minutes.

The suspect is the K40 relay in the module box under the hood next to the passenger side hood hinge. This relay costs around $160. Additionally a faulty K40 will not store codes in the ECU and I presume a diagnostic scan has already been performed when you have already had the car in with Mercedes.Other issues have been known to develop with the wiring harness that eventually disintegrates through age and ends up sending intermittent faults to the ECU.

However, a wiring harness is an expensive fix and given how common the K40 relay issue is with this car I would advise this as the first issue to investigate.

Thanks for using FixYa.

For quite obvious reasons FixYa does not allow experts to issue bypass routines.

Your only option in this instance is to take it to a dealership or a car entertainment installer of good repute.

I am sorry but hope yo understand.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

Check if your battery has enough power by testing the voltage and if possible try to jump start the car.If that does not solve then you need to check the starter motor but it may be some other problems.Hope this helps.

May have a bad connection on the door pin switch. Remove the pin switch, and make sure the connection is tight.

4.6 Northstar V8. It is located on the rear of engine (driver side) in front. It is in the the water pump housing cover. Remove air box and intake tube and bottom radiator hose. 2 bolts(believe 10mm) on thermostat housing. These systems are a little finicky about air pockets....so fill slowly and let run at idle until operating temp and let cool and check level.....fill as needed and repeat if needed.

A faulty central locking system might be due to several reasons, such as a blown fuse, faulty solenoid, or electrical wiring issues. Also, it's good to remember the fault might not be with the central car locking system but the key fob instead; over time, fobs require battery changes.

Hi, You need to check the output on the charger first, with a meter. Let me know and we will go from there.
