2007 Buick Lucerne

How can one get the fault codes on a 2007 Lucerne without a scan tool? I have a 96 Caddi and I can run a diagnostic through the digital gauge panel. Is there a way to do this same thing on the Lucerne?

Thanks

Hello,

You must use a scanner to get the codes the Buick is not like the old Cadillac.
