It is very common for the wires to and around this connector to break seat-side as they are very fine conductors indeed and this is compounded by a slight design flaw, in that the cable that enters the seat base to the matrix is tie-wrapped to a metal seat component which in turn causes a stress fracture along the wire length where fixed. I disassemble the instrument cluster to change several lamps and then re-installed. The mechanic has changed several parts including the mass airflow sensor, both the main and auxiliary batteries, but to no avail. Very high voltages are present and moisture is not friendly to this kind of lamp. All the best Steve Hi Steve, I have changed the double passenger seat in my 2014 sprinter to a single.
A message on the dash board told me to visit a repair shop as soon as possible. While driving approximately 45 mph, the vehicle crashed into the rear of a second vehicle. This has left the middle seat seatbelt tensioner missing from the airbag system. The cause of the failure was not determined. You will have to carefully clean them out with a stiff paintbrush and vacuum cleaner, then spray electrical contact switch cleaner into the buckle aperture while latching and unlatching the belt. The service advisor stated that the stalk was faulty and it was replaced, but, t he seat belt warning light remains on.
In short, I called an auto electrician Brian Dolan who works in West London and we both proceeded to remove as much of the ancillary items from the dashboard as we could including the floor liner. Hope this helps a little, Do let me know how you get on. Of course its down to the nature of the fault that will affect what gets deployed and what does not in event of an emergency — so you are best advised to get it dealt with asap. If you have never had Tele-aid option, then one of the air bag components is being read as coded incorrectly by the control module. Then use a quality switch cleaner sprayed into the clasp working the latch with the seatbelt for a while.
I hope that is of some help, All the best Steve Hi Mohit, If the code is the 9030 code, it is with regard to the tele-aid system. Sounds like it should be noted as a weakness if its as it left the factory. More reading on the subject here and a couple of suggestions where to get it repaired. Use an electrical contact spray inside them to finish the job. I think my first attempt at this would be to fit an occupancy emulator to the passenger seat, its a cheap fix and would be the thing to do before going deeper into other components or modules. This sounds hard but the back of the fuse board is big enough to get your hand through We then pulled the 2nd part of the same loom from which feeds the ignition, lights and instrument cluster through towards the right of the van so we could fix the length that runs from the radio hole and behind the instrument cluster.
More often than not if the issue is with the internal switch its with debris preventing it operating correctly more so than a contact fault within the microswitch. It sounds like you have lost a supply to the electronics. The driver sustained chest and torso injuries, which required medical attention. This may be your issue and was quite common of the era, especially in the S class. Does this mean simply disconnecting the seat pad connector plug? The cause: We think the main short was on a sub loom that goes to the instrument cluster back to the 28 pin connector on the fuse board. This sequence triggers a very annoying bell while I reach for my belt.
If they are covering under warranty thats great! If you do not have an emulator then the most common problem is the seat switch matrix in the seat base. Best regards Steve Hi Steve, I had a great experience with a Mercedes specialist on my 1999 W210. The fault was a worn wire just behind the light switch on the far right of the dashboard. Hope this is one help Steve Hi Steve, Thank you for a great website your very helpful article. Upon restarting the engine everything was normal. I have not been sent anything from mbenz notifying of this issue. Chances are the two problems are not related at all.
A friend of mine informed me that the car does not start for safety reasons since the malfunction of the airbag can bring danger to the occupant. I have no way of knowing if the the safty systems are operational or not. Cause is usually bad or worn electrical pump motor brushes. We found more burnt wires from the brake pedal switch back to the fuse board. The vehicle operated as if it was paralyzed. This switch gets corroded with all kinds of sand, dirt and grime that falls into the buckle.
I found myself not strong enough to press on the brake pedal for adequate braking distance. I'd trust the engineers on that. Worth a go if you can find a used part cheaply enough. The dealer tech would have had to remove the seat to fit this. Replace the wires and re-wrap the loom and refix it.
I have searched high and low and cannot find even a parts explosion of the dash to assist you in how in all comes apart. The vehicle was destroyed and towed. Would you have any clue what would cause the errors or how to fix them? If it was not a coincidence when passenger got in it may be to do with passenger side seat belt ''connections''. All the best Steve Hi John, If the temperature is not high and everything is normal then you could have a cluster fault. Anyway, I pulled the two seat belt wires drivers side from the yellow harness and connected them together.
The electrician had access to Autodata so we could see the wiring schematics which really helped to make sure no random control units were in play half way along a loom. The most common problem is with the rear brake lamps or the pedal switch faulty above the brake, both are a cheap fix. Best Regards, Brian Hi Brian, I have a feeling there is a speed signal loss from somewhere. I live in South Africa and have a 2006 C180K. The van was drivable, but the brake lights were always on ans it blew a 7.
