Test Phases, Quick Test Fuel Tank System: Reference

Reference phase for leakage, and operating check of the leak diagnostic unit (DMTL), is in progress.

If no fault is detected during this phase, the check for major leakage starts.

If a fault is detected during this phase the test is stopped and the parameter "DMTL, test status" shows "Fault Found". The diagnostic trouble code (DTC) for the detect fault is stored in the Engine control module (ECM).
