Road Testing Vehicle
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 DTC or symptom condition. Before road testing a vehicle, ensure that all components are reassembled. During the test drive, do not try to read the DRBIII(R) screen while in motion. Do not hang the DRBIII(R) from the rearview mirror or operate it yourself. Have an assistant available to operate the DRBIII(R).
