1. If the inspection reveals obvious concern(s) that can be readily identified, repair as required.
2. If the concern remains after the inspection, connect the scan tool to the data link connector located beneath the instrument panel and select the vehicle to be tested from the scan tool menu. If the vehicle selection cannot be entered:
- check that the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.

If the scan tool still does not allow with the vehicle selection to be entered, refer to the scan tool manual.
