PURPOSE
This drive test will be used when either of the two conditions listed below exists.

Required Repair Verification
This drive procedure will be used after all vehicle repairs. Once a vehicle has been repaired, it is necessary to verify the repair by driving the vehicle. This is because the anti-lock electronic control unit is unable to detect some system concerns until the vehicle is being driven a certain way. Therefore the drive verification test is a very important step.

Symptom Evaluation Drive

In these situations there may not be a clear system concern to troubleshoot. In this type of situation, this drive test is designed to produce common system concern symptoms. Use this drive test to determine a symptom. Once a symptom is found, a symptom troubleshooting procedure can be followed to repair the vehicle.
