ECM failure - can I swap & do I need to reprogram?
I just had the CEL come on this morning. I had the codes checked, P1607 (ECM circuit failure) & P1259 (VTEC system malfunction). I'm guessing the P1259 comes from the ECM failing.
I've called around and a new ECM is about $825. I can get a used/salvage one for about $125. Shouldn't be too hard to swap. Just need to pull the center console. Do I need to reprogram it? I found one on eBay that should fit. I know I need one for an AT, but I don't know if I can just pull one from an LX or EX and drop it in my SE. |

go with the used one,
u wont need to reprogram it... just plug n the new/used one |

With a 2000? You have a immobilizer if I'm not mistaken - which would require the ECU to be reprogrammed.

Mine's a 4cyl, 2.3 VTEC ULEV, AT, w/AC, no California emissions. But I'm not sure if I can just pull one from any 2.3 VTEC with an AT. I'm hoping that I can, just go in and have it reprogrammed, and drop it in myself. |

You need to get an ECU for a 98-02 automatic F23A4, 2.3L VTEC ULEV. A regular 2.3L VTEC will not work properly with the ULEV sensors.

Thanks, Ghost. |

I got a new ecm for my car, exact replacement. I talked to the dealer, and they'll reprogram it for me for $100, but they said they need the car to do it. That doesn't make a lot of sense to me.
Anyone have a similar situation? How did they reprogram the ecm? |
Re: ECM failure - can I swap & do I need to reprogram?
I believe they need the VIN and can go by that.
