Solution - DO NOT RUN A SERVICE REGENERATION OR CRYSTAL SUBLIMATION TO EXIT INDUCEMENT FOR THESE CODES. - IF THE CHASSIS CAME IN WITH DERATE WARNINGS ACTIVE, Proceed to section two Prior To Programming. I. Software Levels Verify the chassis emissions level - Details can be found in the Product Details box on the Product tab in PTT as seen below: Review the Detailed Status Information for the relevant code on the DTC Readout. For US14+OBD13 - Refer to FSB 284-066 Engine Control Module (ECM) and Aftertreatment Control Module (ACM), Reprogramming. • This bulletin is current as of 17 April 2018. For US14+OBD15: - Software improvements have been released to address this code. Refer to the table below: For US14+OBD16 - Refer to FSB 284-065 Engine Control Module (ECM) and Aftertreatment Control Module (ACM), Reprogramming. • This bulletin is current as of 17 April 2018. For All US17+OBD* - Verify software levels are current. Update if they are not. Note that per FSB284-067, the software released for GHG17 vehicles did not address these codes. - Proceed to Section II. If software shows to be current, ensure the Confirmed DTC status is True as shown above, then proceed with diagnostics below. 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. Internal comments (BO) Do not recommend EECU /ACM replacements for this issue. Recommend GD along with this CBR. If the truck has been in multiple times for this issue, recommend thorough inspection for any clog/electrical issues.
