If a customer comes into your dealership and demonstrates the condition above, refer to RMI for troubleshooting procedures for specific fault codes.
Complete the procedures attached below for injector cleaning.
1. Check SIR for “complete” next to E290A. The vehicle SIR is also available in .pdf format under “Attachments” in Service Management. If “complete”
shows next to E290A, the cleaning has been previously performed. See warranty section for filing instructions on vehicles that require additional cleaning.
2. If E290A does not appear in SIR, check the Asset Service History under the Asset Profile in Service Management to ensure another dealer has not
recently completed the repair.
3. When completing this cleaning, make sure to manually enter E290A in a new operation line in Service Management when starting repairs to ensure
the repair is tracked properly.
4. Print the E300 Driver’s Information Packet (attached below) and fill in the warranty end date and mileage information on the first page for the chassis.
Refer to E300 for specific limitations of in-tank additive reimbursement.
•Check the vehicle in SIR to determine end date and mileage of any applicable engine warranty. The warranty start date is the vehicle “In Service”
date.
