Hey there, thanks for the question.

Is that a U1000 code? or a U0100 ?

Customer: replied 11 months ago.
U1000 sorry
Expert:  Jake replied 11 months ago.

ok, anytime you have a U1000 code we need to start there because its a communication code indicating a major control unit communication issue.

this could be something minor like a bad ground or a weak battery, or something more concerning even like a control unit issue.

Expert:  Jake replied 11 months ago.

I would start by checking the battery and ECM grounds and making sure they are clean and tight. If they are test the battery and make sure its good for starters.
