Just understand that if certain modules are replaced e.g.
INPA is easy to install, and easy to follow. PROGMAN is usually teamed with DIS and is the coding system. You can do a little with programming the keys but that's all.ĭIS is the original dealer system, and provides a diagnosis and a logical test plan to follow to troubleshoot your issues. INPA is a good starting point as its for diagnostics only, so you can't really mess things up.
