Diagnostic Test Drive
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
When servicing vehicles, the vehicle antilock brake system (ABS) and traction control system (TCS), test drives will be necessary to allow all tests to be run, and all system functions to be enabled and exercised. A test drive may also be required to duplicate specific DTCs covered in this article. The diagnostic system check (including test drive) should be run when vehicle repairs are complete in order to verify the repair.
The diagnostic test drive will vary for ABS/TCS problems.
- Read the Diagnostic Aids and the Conditions for Setting the DTC.
- Reconnect any previously disconnected components.
- Start the engine.
- Drive the vehicle under the following conditions for at least 10 minutes. At no times should any unlawful or unsafe maneuvers be performed.
- Highway driving
- Rough roads
- Verify the customer's concern and duplicate driving conditions.
- With the engine still running, use the scan tool and check for any DTCs. If any DTCs are set, perform the appropriate DTC table.
