Service Information: I/M 240 emissions testing on dynamometer

26.08.2016

The enhanced Inspection/Maintenance emission testing program (I/M 240) is in effect in several states.

It is recommended that all vehicles be tested on a 4-wheel dynamometer.

The following vehicle may be tested on a 2-wheel dynamometer:

Mercedes-Benz vehicles that are 2WD and not equipped with Acceleration Slip Regulation (ASR)

Mercedes-Benz, Maybach and smart vehicles that are 2WD and have “Dyno-Mode” capability (must be activated)

The following vehicles must be tested on a 4-wheel dynamometer:

Mercedes-Benz vehicles equipped with ASR

Mercedes-Benz vehicles equipped with 4MATIC

Mercedes-Benz vehicles that are 2WD and do not have “Dyno-Mode” capability

Please see Attachment 1 for a list of vehicles that must be tested on a 4-wheel dynamometer.

Please see Attachment 2 for a list of vehicles with “Dyno-Mode” capability and the activation procedure.

According to US Environmental Protection Agency (EPA) procedures, if an emissions inspector has difficulty performing the I/M 240 test on a 2-wheel dynamometer, the following should be considered:

Test the vehicle on a 4-wheel dynamometer, or

Perform an optional emission test at idle +2500 rpm

An emissions inspector should also consider the options above if they are uncertain about the Dyno-Mode activation procedure or is uncertain about which vehicles can operate on a 2-wheel dynamometer.
