Road Test Precautions
Some complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition.CAUTION: Before road testing a vehicle, be sure that all components are reassembled. During the test drive, do not try to read the DRBIII� screen while in motion. Do not hang the DRBIII� from the rear view mirror or operate it yourself. Have an assistant available to operate the DRBIII�.
