I understand. I can address this with customer service and make sure this is a one time only charge.

P1707 isn't a valid code. Are you sure it wasn't P0717 instead?

And, you also have a brake light on?

I'm sorry, I put in your request to cancel the subscription, and it locked me out of responding back to you. I am happy to help you further to pinpoint what's going on with your Cadillac, looks like we got the technical glitch on the site worked out.

Expert:  Jerry Newton replied 8 months ago.

P0717 was pretty common on 96 and 97 Cadillacs. It relates to the input speed sensor in the transmission. This sensor is buried inside the transmission, you have to remove the trans and disassemble it to replace this sensor. GM had quality issues with those sensors in 96 and 97, in the years after that, I don't think I ever replaced another one, but we did a lot of them in those two years.

That is unrelated to any brake system issues, do you have a red brake light lit up on the dash? Any messages about the brake system or anything like that?

Customer: replied 8 months ago.
the brakes as he changed the master cylinder and the brake pads and rotors blood everything and now the brake lights on
Expert:  Jerry Newton replied 8 months ago.

OK, so the red brake light is only on since the brake work was done? It wasn't on before?

Customer: replied 8 months ago.
Was no lite
Expert:  Jerry Newton replied 8 months ago.

Red brake light comes on due to park brake application, most often. Check to make sure park brake release works (it's automatic release, but they do fail on occasion and leave the park brake applied). Otherwise, this light is commanded on by the ABS system, so some diagnostics would be necessary to find out why it's on.

I suspect that your park brake is partially applied. To test this, remove the wire from the park brake switch, and see if the light goes out.
