A Pecus or Config error means there is a control module that is not properly configured or is faulty. It will be difficult to diagnose without a Jag factory tool. Config/Pecus G looks like it is referring to the GEM module located under the passenger corner dash. If you had any electrical work or modules replaced recently they will need to be programmed.

What does the G stand for. Gear box?

I haven't replaced any modules at all. All I've done was put in some LED lights but it took like 2 weeks for the code to pop up after they were installed.

PECUS G should be for the GEM which is the module located under the passenger corner dash which controls most of the body electrical functions.
