check engine light

Can anyone tell me how to assess the codes on 2004 XLR? We have a Deville and know how to assess those. Thanks!

Moving your thread to the XLR Tech forum...

If your check engine light is on and there is no message on the DTC, the only way to get the codes are with a Tech II. Your dealer is your best bet to find out what is going on. It could be a number of things.

Many codes are readable with a standard OBDII diagnostic scanner, as required by federal law. A TechII provides additional diagnostic functions. Do you know the code? Many parts stores will read them for free if you do not have a scan tool.

2004?

Might be as simple as a bad gas cap,,,and/or not re-installed 'tight'?

Best have it checked out though....
