This test is an aid for the troubleshooting of the dosing control system. Use the test to verify proper operation of the system.
The test consists of the following two parts:

The first part of the test simulates what the system normally checks prior to normal dosing operation, but does not require the engine to be running.
This part of the test can also be ran with the engine running.
Successful completion is required to advance to the next part of the test.
Refer to System Operation, "Dosing Control System Operation" for further information.
After successfully completing, the pre-priming part of the test the user has the option of running the pump on dosing check.
