Fault-tracing information, quick test does not start:

The control module is unable to run the reference phase to test the leak diagnostic unit. This may be because the conditions for starting the quick test of the fuel tank system have not been met, that the fault occurred during fault-tracing or that the fault existed before the fault-tracing began. Check that the hoses, connectors and components etc have been correctly reinstalled. Check that they are not damaged.
HINT: Exit the fault-tracing for this fault. Then read off the diagnostic trouble codes (DTCs) from the vehicle communication socket (central electronic module (CEM)). Fault trace any other diagnostic trouble code (DTC) that is stored in the control module.
Remedy as necessary.
Select a suitable alternative to continue:
1. Start this fault-tracing from the beginning again
  Refer to Checking other diagnostic trouble codes (DTCs), engine control module (ECM)
2. Cancel fault-tracing for this fault.
  OKAY: Troubleshooting has been completed.
