Diagnostic Notes

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 antilock electronic control module 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 -- When a vehicle is brought to the dealer, the customer may only have a general concern about the way the vehicle is braking. 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.
