Customer Question
My 2005 prius just...

My 2005 prius just had the master warning light come on. I tested it and had the following code come up: C1310 HV System What does that mean, and how do I fix it?

Mechanic's Assistant: Just to clarify, what are the exact lights you're talking about?

Red triangle, and car with exclamation mark in it, the vsc and circle with exclamation mark

Mechanic's Assistant: Are you fixing your Prius yourself? What have you tried so far?

I am trying to fix it myself. I ran the codes using my techstream mini VCi cable

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No, I think that is it

That C1310 code just means there is a chassis detection of a problem in the HV system in this case it's the ABS unit that recognized a fault in the HV system. Will your scan tool access the HV ECU to pull codes from it or from the check engine light system//engine control computer?
