Question

I lost power due radio install. How do I reset code?

Answer 1

HI there

If the keep alive power is back to normal the code should reset itself. If not, then you will continue to have this code. If it's possible you could try to clear it with a code reader or scan tool to try and solve the problem. If the code won't clear, then the keep alive circuit still has low power.
