Note for display field 1:  
Display field 1 is the most important. This indicates which system was checked via On Board Diagnostic (OBD) since the last 
time DTC memory was erased or a new control module was implemented. After DTC memory is erased, all testable values 
are set to 1, after the test is performed, the values are set to 0.
