Frequently Asked Questions: OE 12834402-00
The label on my old unit shows a different code. Which one do I quote?
Quote whichever you can read, and tell us both if you have them. This control unit is known as 12834402-00 and as SCEA-3658100E, and the label on a fitted unit often carries the second one. Read the full string from the label rather than a shortened version, since a single character at the end can separate two builds. Send what you find through the quote route on this page and we will confirm it against the OE number before anything is arranged.
Should a professional fit this?
Yes. This unit is safety critical, and it sits at the centre of the restraint system on the car. Work of that kind belongs with a qualified technician who has the diagnostic equipment to disable and re-enable the system properly and to clear the stored faults afterwards. We do not publish a fitting procedure on this page and nothing here should be taken as one. Line up the workshop first, then enquire through the quote route so the timing works for both of you.
How quickly will this control unit reach me?
The delivery time is 8 to 25 days, from order to door. Check the parcel is undamaged before you sign for it, and compare the unit against your old one before it goes to the workshop for fitting. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12834402-00.
What is the unit itself made of?
The housing is plastic and the unit is supplied new. Since it is a plastic case, it does not enjoy being dropped or left loose in a boot, so whoever collects or receives it should keep it boxed until the workshop is ready to fit it. Check the OE number on the old unit against the OE number shown on this page before you order it.
Where in the car does this unit live?
It is an interior mounted unit, filed under airbags and SRS. No side applies to it, so it is treated as a single central item rather than a handed pair. Access on any given car means trim coming away, which is another reason the job goes to a workshop rather than onto a driveway. Confirm your model and build year in the fitment table on this page, then send the details through the quote route so the right unit is identified before anything moves.
Is there a cheaper alternative to this unit?
No, only one version is listed here. BYD is named as the manufacturer of the Original/Genuine unit and no Aftermarket manufacturer is listed for 12834402-00, so one version is all that is available. Restraint electronics are coded to the vehicle, which is part of why only the one version exists. If you want us to check whether another reference applies to your car, send the OE number through the quote route on this page and we will tell you what we find.
