Test Driving ABS Complaint Vehicles


Test Driving ABS Complaint Vehicles
In case of an intermittent ABS lamp illumination, see "Diagnosis by ABS Warning Light illumination Pattern" or go to 5A-37. In some cases, the vehicle may need to be test driven by following the test procedure below.

1. Start the engine and make sure that the "ABS" WIL goes OFF. If the WIL remains ON, it means that the Diagnostic Trouble Code (DTC) is stored. Therefore, read the code and locate the fault.

NOTE
The DTC cannot be cleared if the vehicle speed does not exceed 12 km/h (8 mph) at DTC, even though the repair operation is completed.

2. Start the vehicle and accelerate to about 30 km/h (19mph) or more.

3. Slowly brake and stop the vehicle completely.

4. Then restart the vehicle and accelerate to about 40 km/h (25 mph) or more

5. Brake at a time so as to actuate the ABS and stop the vehicle.

6. Be cautious of abnormality during the test. If the W/L is actuated while driving, read the DTC and locate the fault.

7. If the abnormality is not reproduced by the test, make best efforts to reproduce the situation reported by the customer.

8. If the abnormality has been detected, repair in accordance with the "Symptom Charts".

NOTE:
Be sure to give a test drive on a wide, even road with a small traffic. If an abnormality is detected, be sure to suspend the test and start trouble diagnosis at once.
