    Hi all.. 07 Prius. VSC Triangle of death and brake lights illuminated. Went into limp mode immediately. Pulled HV battery and all cells are 7.7-7.8. 2 codes are stored C1259 and C1310 Hv battery is good and am stumped now. Any help to fix this issue will be greatly appreciated. Thanks for your help and time .

    Those two codes just mean that the hybrid vehicle control ECU has a code. The scanner that you are using is not capable of communicating with that ECU. So, you need a more capable scanner to read all the codes that your car is trying to tell you about.

    Where in Maryland do you live. If it is close by, I may be able to help.
