Diagnostic Mode 6: Check Test Results of Components Not Continuously Monitored

Diagnostic mode 6: Check test results of components that are not continuously monitored

Note: This diagnostic mode can only be selected with Module number 10 - Engine Electronics.

Function
This diagnostic mode displays the test results of emission relevant components and systems which are not continuously monitored.
The values of individual test results must reach the specified value or must be within the min.- and max.- limits.

Test-ID Components Test
01: Catalytic converter monitoring
03: Secondary Air Injection (AIR) system Sedan > 08.99
05: Tank ventilation system

Test-ID 01: Catalytic converter monitoring

Test requirements
There must not be any DTCs stored in DTC memory.
Coolant temperature must be at least 80°C.

Procedure
