Action
Fix-As-Fail
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.
Troubleshooting, admin time, and verification steps are NOT included in the cleaning Quick Claims. Use the
editable Quick Claim (E290A) or file a separate claim for additional time and materials.
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.
