Hello

My brother has a ZR1 and search a Diagnostic Software like autotap for C5 for his ZR1.

It can be a Handheld or Software for Laptops.

The Software must show Error-Codes with meaning and delete the Error-Codes.

All of this can be done through the Driver Information Center and a paperclip jumping the correct pins on the OBD connector.

or one can buy a obd1 scann tool like a auto xray. i believe the best tool for this is a tech 1 scan tool that the g m mechs use

diacom (DOS) and EASE (windows) and Autotap are good choices as well. the Tech 1 will do everything but if you have a laptop, these others might be preferrable.
