II. System Tests
Premium Tech Tool (PTT) Operation number 2589-08-03-05 Aftertreatment selective catalytic
reduction (SCR) system, found under Function Group 2 in the Test tab should be utilized to
diagnose the problem and exit inducement in the order listed below:
1. Test A: System Pressure Build Up
- This test confirms that the DEF pump builds pressure as expected (this test can be skipped
if other tests will also be performed).
- IF PRESSURE IS NOT BUILT, DO NOT REPLACE DEF PUMP. Follow the instructions below:
1. Start the truck and allow it to run for 10 minutes.
2. Shut off the truck.
3. Rerun the test.
2. Test B: Dosing Test
- A graduated cylinder or other appropriate container with measurement accurate within 2
milliliters (cubic centimeters) should be used to measure dosing test results.
1. Sub-Test 2, Small dosing test - 120 seconds at 25% dosing
2. Sub-Test 3, Large dosing test - 120 seconds at 100% dosing
3. Sub-Test 4, Dosing Test, Exit inducement mode - This will clear any inducement
(derate) condition caused by P208E or P103B.
3. Test C: Exit Inducement Mode
- Test B, sub-test 4 mentioned in the previous section runs the diagnostic monitor on the
dosing valve and verifies it is operating correctly. Test C will reset any inducement (derate)
timers present.
- This test should be run as the last step before releasing vehicle back to the customer so that
if the problem is not completely fixed, the driver will still have 4 hours to reach a service
location before the vehicle begins going into severe derate.
