Enter Diagnostics Again

Verify ARC/EVO test connector (right front shock tower) is clean and corrosion free. Repeat attempt to enter diagnostics (see QUICK TEST A1). Be sure tester switch positions and procedures are followed. If second attempt to enter diagnostics is successful, proceed from QUICK TEST A1. If second attempt fails, proceed to QUICK TEST D2.
