    Hello everybody, First of all, even though this is the first post, I have been using all of your advice to solve the problems in my little Prius and for that, I am very thankful I found this forum and your knowledge.
    I live in Guaymas Mexico and owned a gen 2, 2006 Prius and LOVE it, it has 184501 miles I bought it used and at that time it had about 90k miles, about a month ago I had the red triangle lite up and codes that came up directed me to the Hybrid battery, sorry I wrote down the codes and now I can not find them, so at that time I took the Hybrid battery out and found one module at 6.71 while the rest were in the range between 7.96 and 8, since then I have used it a few times and finally have the money for the parts needed, so yesterday I took it apart again to double-check if I would need more than one module, well lucky me, I still only need the one module, the problem is that I put it all back together and I am not getting the READY light on and of course it will not start, I have checked the #31 fuse under the hood, the big fuse inside the orange plug for the hybrid battery and a follow all the right steps to disconnect and reconnect both batteries: 1-disconnect plug for the break system box next to 12v bat. 2-disconnect NEG terminal of 12v. 3- remove the orange plug at the hybrid bat. 4- remove the hybrid bat. and test all modules the bad one showed at 6.45 and the rest were at the range between 7.78 and 7.88, clean all the copper plates that connect the terminals of the module on both sides and put it all back together again with following steps: 1- connect 12v NEG bat. 2-plug in break box next to 12v bat. 3- connect 3 small harnesses into the hybrid battery and the 2 orange cables in the opposite end 4-inserted orange plug-in hybrid bat.
    I almost forgot I did notice that the brake light in the dash is always ON even if the emergency brake is off, the little light on the power button is always orange and when I put it on gear it only goes to N.
    Any help will be greatly appreciated and thank you

    There is no need to do this, but won't hurt anything if you do.
    Did you do all three steps to reinstall the safety interlock?

    Dolj, I have to THANK YOU!!!!! I came back to your post and realized the last step for the orange plug is to push down to completely connect it to the system, for two days I was FREAKING OUT because of that one very important step!!! again thank you very much for the illustration, like they say a picture is worth a million words!!!! got it running again!!!!!
