Fault-Tracing Information

Fault-tracing

Checking the status




In order for the diagnostic trouble code (DTC) to be diagnosed, the engine must be running.
Start the vehicle and then read off the fault status of the diagnostic trouble code (DTC) without switching off the engine.

Check whether the fault is permanent or intermittent. Read off the diagnostic trouble code (DTC) fault status when the diagnostic status is "Completed".
The fault is permanent if the fault status is "Fault found".
If the status is "No fault found" this indicates that the fault is intermittent.
