Road testing vehicle
- Some DTCs are only recognized by the On Board Diagnostic (OBD) while the vehicle is moving. You can check the system during a road test. During road test, drive at a speed of at least 60 km/h for 30 seconds. Check traffic conditions and perform an ABS regulated braking when appropriate. You will feel a pulsing in the brake pedal indicating the system is active.
WARNING:
Driving the vehicle after On Board Diagnostic (OBD) has detected a malfunction presents the risk of accident. The brake system will only be partially functional. Because brake pressure at the rear wheels is no longer regulated vie Electronic Brake Distribution (EBD), the rear wheels tend to brake excessively. This causes the rear of the vehicle to break loose.
When the use of test equipment is required during road tests, test equipment must always be secured to the rear seat and operated from there by a second person. If test and measuring equipment is operated from the passenger seat, the person seated there could be injured in the event of an accident involving deployment of the passenger-side airbag.
