Toyota 7FBEU18 AD-4 and AD-3 error

I am getting a AD-4 and then sometimes an AD-4 and AD-3 error.

The machine will not travel.

Thanks.

Thank you.

It was the Danaher Drive controller DH38R09192A.

Found the refurbs at uniparts.net for only $450.

One of the Onboard Controllers for the Drive Motors is defective.
Might need to replace it, unless your customer decides to have it fixed.

Test both motors for voltage; you need to see which one is not receiving volts.
Then do the same thing for the Controllers.
