blownengine Posted July 30, 2011 Report Share Posted July 30, 2011 So, been working on my friends car for the past couple of weeks, some of you have probably seen the build log. Its a 2011 VW Jetta. Anyway the first thing we did to the car was install his head unit, speaker amp, and speakers. Ever since then his airbag light has been on, meaning his airbags arnt working....Kind of a big deal. I only have two ideas as to what happened. 1. VW doesnt use a remote wire to turn on their radio. Its weird they use some kind of CAN BUS adaptor thing. So for the remote wire I ran some 18 gauge to the fuse box under the dash and tapped in there. None of the fuses are labeled so I just picked fuses until one worked. So I could have done something there. Note: Even if I switch fuses the air bag light is still on. I have also never put the stock radio back in to see if that fixes it. Thats the first thing I will try. 2. This one is kind of a shot in the dark but just by taking out panels and such I could have messed with a connector. I never unplugged anything but you never know with new cars. They can be picky. Please drop a suggestion. We need to get this fixed because air bags are important.

EVAlonSo Posted July 30, 2011 Report Share Posted July 30, 2011 (edited) Did you turn on ignition with any airbag plugs/ sensors unplugged? Sorry reading owns me. just saw you didnt unplug anything Maybe try running your remote lead to ignition instead of a random fuse? that could be an issue. Make sure you fuse your remote wire. even though the vehicle has one, just do it anyway Edited July 30, 2011 by EVAlonSo Quote MECP MASTER CEA208509 Proud employee of Alarms, ETC in lakeland, FL ASE certified 2002 Tacoma: 4 RF P3 15s @ 28hz 2 RF T1500-1bdcps 2 pair Kicker QS 4 Pair RF Power 6s 3 RF p400-4 1 RF p200-2 ALP CDA-9887 Link to comment Share on other sites More sharing options...
mbdblue Posted July 30, 2011 Report Share Posted July 30, 2011 I think the obvious decision would be to see if you can find out what fuse you tapped. its possible it is somehow connected to the SRS or airbag system. theres gotta be a way to figure out which fuses are which Quote AA-Atomic-Clif Designs-DC-Diamond-Digital Designs-Directed-Eclipse-Fi-Hertz-Hifonics-Kenwood-Memphis-Phoenix Gold-Pioneer-PPI-PSi-Stinger-Sundown-TC Sounds-Viper-Zapco Link to comment Share on other sites More sharing options...
EVAlonSo Posted July 30, 2011 Report Share Posted July 30, 2011 You said you installed a head unit as well. being that there is no switch power, did you just use your remote wire as a relay for constant behind the radio?

But maybe unplugging the fuse did something and the system has to be reset or something. Idk, I didnt design the car.

jmilch Posted July 31, 2011 Report Share Posted July 31, 2011 Throw the stock radio CAN BUS adapter back on the stock HU and see if the light goes away... You may need to buy a bypass adapter if that is the case. I don't know the particulars of this car, but I have used them on other cars.

You may need to buy a bypass adapter if that is the case. I don't know the particulars of this car, but I have used them on other cars. There is no physical adaptor, unless its built into the stock radio. The radio has power and ground just no remote. It would have made my life a lot easier if they would have dont it the normal way. Next time he comes over we will plug the stock back in and see if it fixes it.

Emmet Posted July 31, 2011 Report Share Posted July 31, 2011 Heard about them new vw`s. It happens when you try change radio, even if you didnt disconnect the battery you probs tripped it by removing the wiring harness. You need a vag-com to reset it or take it to a dealer, they`ll probably charge you for it though.... Or else search for places with one who could do it for you. Quote i shook this one kids hand and it just folded in mine. long story short i fucked his girlfriendso.. yeah.. You want this to happen to you? Give decent handshakes people.
