Drive Test Description

PURPOSE
This drive test will be used when either of two conditions exists;
1. Recommended Repair Verification
This drive procedure can be used after all vehicle repairs. Because the ABS module is unable to detect some system concerns until the vehicle is being driven in a certain way, this drive test can be helpful in developing further confidence in the 4WABS system operation before delivery to the customer.

2. 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. 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.

DRIVE DESCRIPTION
This is designed to be a generic drive test that is used for three purposes listed below.
1. To verify a repair of the ABS system on a vehicle.
2. To attempt to recreate an intermittent concern.
3. To attempt to detect a symptom when a diagnostic trouble code or a concern symptom is not known.
