- I have been asked quite a few times about repairing abs and airbag wiring harnesses on modern vehicles. I try to answer or make videos whenever I can find the time. I know this is a basic video but hopefully it will help someone trying to diy their problems.
It was not a boring video, thought it was useful and interesting.
A + Rating. Simple to follow, for us amateurs. Thanks for the video.
Well done :-D Good explanation of how properly connect two wires. I discovered as well the in the last months the solder-shrink connectors to a neat job. Sadly they are more expensive but very good for special applications. I used them often for Vp30/Vp44 pump repairs :-)
Not boring at all very interesting 👍👍👍
Right on, let me know how you like it. We have a Pico 4425 at the shop, I have my own pocket scope, I wanna get my own Pico but also might get the one for the Autel if it is decent enough.
I love those green electrical tools from the Homless deathspot
Great information! I'm about to connect four airbag wires together and you have just showed me exactly what I was trying to vision in my Head.
I am rebuilding a car which rear-ended a truck. So far everything is going well. Maybe I need to become a mechanic or something. Currently I am just working in warehouse. Never could figure out what I wanted to be in life.
Great channel. I rebuild and program clusters/modules and it’s nice to see someone out there doing the same thing. A quick tip, after soldering the wires together I take pliers or needle nose and crimp the solder flat/smooth. I’ve had little wires stick out of the solder sleeve and create problems down the road! I’m an ex-aviation electrician but now do clusters full time. Keep up the good work my friend!
Make some videos!
Thank you! Great video.
We've been using those solder sleeves on Benz for years. They have had multiple DTB's for SRS wire repairs, I love those sleeves and only use those (have only used the ones supplied by Benz) for repairing wires. I will also use heat shrink over the sleeve.
Do you have a part number for the sleeve to repair impact srs wire ?
@@siksclass I can't it when I'm at work next week. You can buy similar ones on Amazon that work just as good, I use those too. Just Google solder sleeves
@@danjensen100 thanks a ton. I'd still be interested in learning if there is part number available for this from benz. Haven't reached out to a dealer yet, but wanted to check in with you first.
With respect, the two methods for checking the quality of a repaired connection is first using an AC milliohm meter or using a time domain reflectometer. The reflectometer is excellent for evaluating long harness impedance changes through each connection or connector. It will also show where coax cables are damaged. It will show the magnitude of the impedance as well as the distance along the cable of each change in impedance.
Hey I got a question just did a swap of seats on a Mazda a previous seats had airbags and the new ones came out from a Mazda also and got airbags but with different connectors it's possible to just cut the connector and connect the cables?
I've been enjoying your videos! Just curious what your thoughts are....most connector & tool manufacturers say you should use the stake crimp only on bare insulated connectors (opposite the split as you noted). They say to use the crimp die with the smooth oval jaws for the insulated connectors(the innermost die on yours). I only started doing it the "correct" way 5 years ago after 25 years doing it wrong but I don't think I ever had a failure unless it was on those cheap hard brittle plastic insulated connectors or if I overcrimped crushing/cutting individual strands with the stake. I've never got a good explanation for the "correct" way.
I've always been taught to use the half round with stake (outer most on my cutters ) on any connector. Insulated or not. The split goes opposite the spike. I have been doing it that way since 1992. I was taught that if in doubt try to pull the wires apart. A good staked connection will break small to medium guage wire before the connector will fail. I do know i repair regular crimped not staked wires on a regular basis especially those choice by stereo and alarm shops. I swear they do the quickest and sometimes nastiest wiring jobs I've ever seen. Most mechanics take pride in their repairs and try to learn the correct way to do things. I'm not saying i'm always right but using the stake and half round crimp has never let me down.
Hi, I bought a car that someone pulled the wire out of the knee air bag at the connector, on a 2014 Charger. I got a new connection end with wires attached. The problem is I can't find any info as to which direction the two wires should be attached. Do you know if it actually matters? Thanks
👍👍
Dear Jack!! I'm stuck, hoping you can help me. I'm replacing my 2013 Town & Country airbag, but the pigtail wiring on the new airbag has YELLOW-BLUE, and RED-BLACK wires, but the clockspring wires are YELLOW-BLUE, and BLACK-WHITE. ?!?! Does the Black go to the white, or am I going to blow this thing up in my face?!!!
I repair airbag wire harnesses all the time. I solder and shrink tube them .
is it safe to solder the wires ? will the air bag system work ?
@@arielbargallo9448 yes it’s safe. This way he does in the video will end up turning the light back on .
How did you get started in this business? I wanna start doing Mobile diagnostics and minor electric repairs but I have no formal training though a very quick learner in most things.
DIY-HAVEN it was a series of events that got me into it. Started out as a mechanic. Went to school to be an engineer for a couple years. Had to quit because my first daughter was born. Got into the it business during the early 2000's when it was booming. Everything crashed so I went back to what I knew. Got to work as a mechanic at a body shop where I got to and had to fix everything on every kind of car. Started my own shop for 5 years lost it during a divorce. Put my tools in a van and knew there was a demand for programming and electrical specialists and since I knew computers, electrical and cars really well is been amazingly uphill from there. So really no tech school or anything. Just a combination of jobs that eventually combined into one.
Practical application... I hear you man. I hope you have more time to do diagnostics videos for ppl like myself. Will really appreciate it
DIY-HAVEN will do. I have a lot I just need to edit. I try to make them every time I can when the opportunity is there to not look like an idiot In front of my customers. Lol. I'll get more posted. I really want to get the nissan ones up because people struggle with them and message me quite a bit.
Man any will be much appreciated. I'm looking to buy the ms906bt to start. After watching your video on it I was pretty much sold. But a tool is only as efficient as the hands (or brain) that handles it. So with a few good videos on the "psyche of diagnostic basics" I think I'll be able to fly on my own
@@Usmanthemecano If you want a good online diagnostics course sign up for ScannerDanner's premium channel. It covers everything from basic to advanced electrical and also advanced mechanical diagnostics using a scope.
Not boring at all a lot of techs need to know this stuff I hate having to follow behind these guys who butcher the wires and splices nothing better the removing a half a roll of black electric tape to see 18 gauge wire splice together with a non-insulated BLUE butt connector
How about an abs wire what do you suggest
If it's not the sensor itself I repair them with the solderseals and heatshrink the whole repair when possible. A lot of abs wiring is shielded near the wheel speed sensors and really typically shouldn't be repaired.
Did you get the oscilloscope for the 906bt?
Dan Jensen I actually just ordered one. Wont be here until next Monday thought. I want to do a review on it. I have a rigol 1104z that I have at my desk. I fix a lot of clusters , pcm's and audio equipment at home. I haven't had much need for a mobile scope since these new scanners stream data so fast and the codes are petty accurate on these newer cars. We used to use scopes a lot back in the day when we only had the mt2500 scanners . I did have a multimeter with scope built in that I pull out occasionally when i think it might be a pcm issue on a sensor circuit just to be certain. I'm going to make a video on how to use a scope properly. I have a friend with a Durango that can't get a speed sensor signal out of the transmission. We're going to check and see if it's outputting a pwm signal from the sensor to know if it's a bad pcm or tone ring in the transmission. The wiring is good and the sensor is new (tried 2) but still no signal.
Hey, shoot me an email when your able (I put my address in your other post) wanna ask about the backup process for the Autel
Dan Jensen just sent it
Thanks, I checked my email but don't see anything. Basically I need some assistance trying to do the back ups to the SD card before performing updates. If you wouldn't mind helping me with that I'd really appreciate it! I've looked everywhere but can't find that info. If you wouldn't mind walking me through it over the phone that would probably be easiest.....in exchange I can assist you with any questions or help you might need on any Mercedes. If your too busy to help me with the backup process I totally understand, if it's something you wouldn't mind doing I'll post my email again, just in case I posted it wrong before. (I'll put it in caps so there is no mistaking the L)

Thanks Jack!
Soldering is not approved by most manufactures, the most common approval methods are duraseal butt connectors, approved by Ford , vw audi group , gm usa and gm Europe , I do solder myself at times , but not often now.regards Joe
Damn pack rat got my harness! Rrrr
Ps they call it a Western union splice because in the 1800’s the western union coach drivers Would have to repair the Telegraph lines Between towns and all they would do is Twist the wires in that configuration and time back to the pole
Thank you in 2024
Do not use butt connectors in a air bag. soldering is best.
