Fixing Airbag Code 27 [Ranger/Explorer/B3000] 

where in the hell do you find a radio shack today????? been gone for a decade or more?

My 2006 Mazda B4000 just did this, (a week before I was going to trade it in), I had no idea airbag indicators flashed codes. A 74 type bulb is slightly different than the original, but it worked. Thanks!

Just finished this repair on my '03 Mazda B2300, worked like a charm! Thanks so much for all the info including how to re-solder the lamp. Really great and saved me a ton of dough. Keep up the good work!

Awesome! One note... the factory bulb is NOT an LED, it's an incandescent bulb shaped like an LED with a yellow sleeve to make it look yellow. Incandescent bulbs burn out much faster than LEDs, so your fix is better than factory. Nice.

Thanks for keeping this video accessible - followed your example, suggestions and steps and within 1 hour, my passenger airbag light was replaced. The whole assembly was replaced and NO AIR BAG flashing on my dash. Thanks for sharing your easy replacement method. chuck

Just did this to my 2000 Ford Ranger. Worked like a charm! My LED came in a bag instead of the packaging yours was in, & the # is now 276-0209. EXACT Same bulb though. Long lead to the inside, shorter to the outside, boom! Problem solved. Thank you sir! Thumbed up.

Thank you sir, just used your video to clear my air bag light, now off to clearing my ABS light next.

Found the exact LED you used at radio shack (The bag it came is had 276-0209 though). Fixed it today. Thanks for the video, no longer driving with a airbag light.

Thank you very much! That noise was driving me crazy. - I used a green bulb to match dashboard lights and it looks great 👍🏼

Thanks for this video, it worked perfectly. I got an orange LED but kept the sleeve on it, and the color looks pretty exact to the original, IMO. This was quite easy.

Worked great, put the long lead on the inside like your demonstration showed and it worked great. Thanks

Thank you Kory, I now know what is wrong, but it make take me a bit to do it since it will be my first time. I now know it isn't going to explode on me going down the road, you have been very helpful. Thank you bunches!!!!!

Thanks for doing this. I'm about to do the same repair on my 2000 Mazda B3000 and was searching for info on how to do it.

desde Argentina, muy buena explicación. Gracias

Great video! I did this repair today using the same led light from radio shack. Worked like a champ! This is a simple do-it-yourself fix that will save you about $250 repair cost. Some comments for others who watch this: - the short leg of the led goes closest to the outside of the board when soldering. You can see this in the video if you watch it carefully. - I found it easier to remove the 3 bolts first and then unsnap the cover once the entire unit, cover and all was unplugged from the circuit. - I ran my solder at about 25W vs the higher setting (45W on my mine). This worked beautifully. Thanks for the great video, Kory! Thumbs up!

Thanks for the video.. same problem with my 2004 ford f250 super duty truck.. bulb on mine was a incandescent, so i replaced it with a 3watt similar bulb. Works perfectly.

When he said he bought it from Radio Shack I knew he was a seasoned working man. This video was probably to detailed for most. Lets be honest most be people will just replace that PCB. When it comes to airbag systems I don't want to mess around to much. But great coverage overall

I truly appreciate this video. You saved me at least 100 dollars.

Thanks for sharing the fix for error code 2 7. I used green LED #272-0334 from Radio Shack. I ordered the bulb online it arrived in a couple days. Took about an hour to complete the fix on a 2003 Ranger and it worked perfect. I do not have the error code now!

thank you so much, this was very helpful. really appreciate it.

Put the bulb in exactly as you did, longer lead towards the center...no more airbag light!!! Thanks very much!

Love this video. It must be the best technical / instructional video I've ever watched on RU-vid, great job. It was well thought out, well presented, taking the viewer from start to finish. Very Very Good if I may critique your video a little. It would be helpful to know what the whole switch price is. You mentioned dealer cost to repair, but was that for the switch only or switch and installation? Anyway I loved it thanks for the video Everyone's a Critic you know

My next project. I just fixed 1st code that was seatbelt connection. My dad was correct when he told me (38yrs ago) to own a truck, buy good tools & learn to use them.

Thanks for this video, it worked perfectly.

Ayyy. Worked for me. So the longer end of the LED is closest towards the middle of the board

I just fixed my 2000 ford ranger, it had the code 27 and i got a led with Integrated Resistor from the shack. not the exact same part # as you but it worked perfectly. Thanks For The Great Video

Code 27 fixed -ford ranger 2002. Ford asked $240 for the airbag switch box. I bought 2 bulbs for $5.95 from Walmart(long life bulb 74) and went to a mobile repair shop to replace the bulb. It took 1 minute and the guy told me I do not need to pay anything but I gave him $10. All fixed around $13.50. Thanks

It’s a great video. However it didn’t fix my 08 super duty’s problem. The led would light up on when I started the truck, give me code 18 and then the led would turn off. Must be some new programming. I’m still giving you a thumbs up for your effort and help.

If you don't have an LED with an internal resistor, you can solder a 220 ohm resistor on to one of the legs of the LED.

I've been trying to find LEDs but most I've found were 20ma max. Was told they needed a 1000 ohm resistor. I couldn't see the labels on the resistors in the video correctly but is that enough?

Great video. unfortunately I have a code 25. do you know what I can do to fix that?

Does anyone know what value resistor to use if you already have a 12-v LED (I want to add the resistor inline) and what LED lead would you put that resistor on? Anode or cathode of the LED?

has anyone been able to find this same LED light in amber color?? i see them but with out the integrated resistor

If the bulb that came out didn't have a diode then why do you need one on a replacement bulb ?

I didn’t feel like getting a soldering iron and stuff so I just ended up buying a new switch. I found one for $70 luckily instead of going to advance or auto zone for $125. Yes I’m that lazy

i bought a soldering iron at homedepot & it also came with small amount of solder but the solder has flux in it, but dont know what type of flux it could be. When im applying the heat to the solder when repairing, it doesn't hold or adhere...could it be a different type of solder i need???

did i miss you saying what led leg went where? You did the trial and error but didnt say if the long leg is on the inside or outside. ty

Do you need to disconnect the battery or do anything else to keep from accidentally triggering the airbag while doing this repair?

Hi, I was wondering if I could go to a local junk yard and pull one of these out of a ranger there, would this work or cause issues with the system?

The led bulb part number you provided is for a red led. Mine uses an amber or white. What is that pn?

My 1998 ranger show flashlight 3 times and after 2 times i dont know how fix

Well Radio Shack is out of business. Anyone have any luck finding the right bulb in another store or online?

wish 6you would have actually shown the removal of the solder and you didn't show which side the short end goes to.

my light works yet I still get an error 27.

PROBLEMA DE ATERRAMENTO DO MODULO!...
