About This Part
Micro power relay for the BYD Sealion 06 and many other current models, OE 12785226-00 and type HFV11/12-HS-R rated 12V 20A. This compact four-pin relay switches an accessory or control circuit inside the fuse box, using a low-current coil to make and break the higher-current load contacts. Fits the Sealion 06 EV, Song L DM-i, Sealion 05 DM-i, Qin PLUS DM-i and more than seventeen further BYD models. The plastic-cased automotive relay is a common replacement when a circuit chatters or fails to energise.

Frequently Asked Questions: OE 12785226-00
This relay covers many models. How do I know mine is one of them?
Wide coverage is common on small electrical parts and it does not settle your own case. The fitment table on this page is what settles it, so read down to your model and variant instead of stopping at the badge. Then hold the description against the part you are replacing, because this one is the 12V unit at 20A and a relay of another rating is a separate listing even where the body looks the same. If your variant is missing from the table or reads oddly, ask us on the quote route.
My old relay is marked 20AHFV11/12-HS-R. Is that this part?
It points at the same item. The reference 20AHFV11/12-HS-R appears alongside OE 12785226-00 for this relay, so a part marked with either number is the one on this page. Different marks appear depending on who supplied or fitted the relay, which is why both show here. Read whatever is printed on the body of the old one and compare it with both numbers. If it agrees with neither, do not guess. Send us the marking you can read using the quote route and we will check it before you order.
When would this relay arrive?
Delivery takes 8 to 25 days from your order to your door. Small parts are easy to forget until the car is already apart, so order this one before the work starts rather than during it. If a date has to be firm, ask us to check OE 12785226-00 before you place the order. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What is this relay made of?
The housing is plastic. That is the case around the relay rather than anything about how it performs, so it is only useful for handling and storage rather than for identifying the part. Keep it in its box until you are ready to fit it, since a small part is easy to misplace once loose. The identification sits in the description, not the case, so match the 12V and 20A wording on this page to the relay you are removing before it goes in.
Where does this relay sit on the car?
Engine Bay. This relay sits under the bonnet rather than in the cabin, so look there before you start on interior panels. This page is written for the Sealion 06 at 12V and 20A. Check your own model and variant in the fitment table on this page, because coverage across a marque is never uniform. If the car carries several relays that look alike to the eye and you want the right one before you order, send OE 12785226-00 to us on the quote route and we will confirm.
Why is there no second version of this relay to choose from?
Because only one version of this relay is set up on this page. The Original/Genuine part from BYD is the one carrying OE 12785226-00, with no Aftermarket option beside it, so the page shows a single tier. That reflects what we currently stock rather than any judgement about parts sold elsewhere. If you have a substitute in front of you and want to know whether it matches this relay, send its reference on the quote route and we will check. An Aftermarket option, if added for this part later, will appear here.
