I just purchased a gen 2 prius, It acts just like a dead 12volt battery except the interior lights and headlights function correctly. The only thing lit up on the dash is a door ajar light. I pulled 2 codes, b2287 LIN communication master and b2289 key collation waiting time over. My service info says the LIN1 wire betwwen the ID code box{possibly the transponder key ecu} and the power source control ecu may be open or shorted. I have pulled the dash cap and need to know where to find these 2 ecu's . Any help out there?
You might have a blown fuse for the invertor coolant pump. Check the 15A AM2 fuse (located on Unit B in the main relay/fuse box) . Brad
All fuses are good. I have figured out the power source control ecu will not power up the 3 relays IG1 IG2 and accy. I put power to them and it starts/ready up. I have drove it about a week when it did it again. I need to know if anyone knows what needs to happen for the power source control ecu to come online?
Here is the work up for both B2287 and B2289: https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Prius%20Service%20Manuals%202004/%E4%BF%AE%E7%90%86%E6%89%8B%E5%86%8C/04pruisr/05/21bi6/cib2287.pdf
