Diagnostic Mode 6: Check Test of Parts Not Constantly Monitored
Diagnostic mode 6: Check test results of components that are not continuously monitored
Function
This diagnostic mode displays the test results of emission relevant components and systems which are not continuously monitored.
The values of the individual test results must reach the specified value or must be within the min.- and max.- limits.
