Frequently Asked Questions: OE 15563731-00
The number on my old control unit reads SC3E-3658100D. Is that the same part?
SC3E-3658100D is an alternative reference for the same SRS electronic control unit, alongside the OE number 15563731-00. Either number identifies it. If the label on the unit you have taken out shows something that matches neither, do not assume it is the wrong item. Send us what is printed on it together with a photograph of the old part and its label using the quote route on this page, and we will check it against the fitment table on this page before anything moves.
Can I fit this control unit myself?
This is the electronic control unit for the SRS system on the Yuan UP. Work of that kind belongs with an auto electrician or a workshop that has the diagnostic equipment for BYD systems and can confirm the car is in a safe state before and after the job. Order the part first, then book the labour, so the vehicle is not tied up waiting on stock. Check the OE number 15563731-00 against the old part before the workshop starts, so you know it is the right unit.
When can I expect this control unit to be delivered?
The delivery time is 8 to 25 days, from order to door. When it arrives, check the parcel is undamaged before you sign for it, and compare the unit against the old one you are removing before it goes anywhere near the car. If anything about the parcel or the part looks wrong, use the quote route on this page and we will sort it out before you fit it.
What is the housing made of?
The housing of this control unit is made of plastic. That matters mainly for handling, so keep it dry and free of impact until it goes in, and leave it in its packing until the workshop is ready to fit it. No further detail on the internal construction is available beyond the material itself, so if your fitter needs more than that, check the OE number 15563731-00 against the old part first.
Where does this unit sit on the car?
The mounting position for this one is interior, so it is fitted inside the cabin rather than under the body or out in the airflow. This does not say which trim panel has to come off to reach it, and we will not guess at that here. Your workshop documentation for the Yuan UP is the place for the exact location. Check the OE number on the unit you are replacing before you order, and use the fitment table on this page to confirm your own build is listed.
Is a second version of this control unit offered?
This control unit is offered as the Original/Genuine part made by BYD, and that is the price shown on this page. No Aftermarket equivalent has been sourced against this reference, so there is no second tier to choose between. Where we offer both, the page shows the two together. If you would rather we looked again for another supply route before you decide, send the OE number 15563731-00 through the quote route on this page and we will tell you what comes back.
