Service
It is not necessary to perform the complete Guided Fault Finding with the VAS tester.
1. Check for Campaign Completion Label
Verify whether a Campaign Completion Label using SAGA Code 28F2 is affixed next to the vehicle emission control information label.
If the Campaign Completion Label using SAGA Code 28F2 is present, do not proceed with this TSB.
2. Address misfire DTCs stored in the ECM data memory
Replace ignition coils (including cylinders without a misfire DTC) as listed in the table. Not all coils may require replacement. (See matrix below for details.)
Note:
To prevent damage, please use appropriate tools to remove coils (such as coil puller tool T40039). Do not twist ignition coil when installing. Do not use any object to tap the ignition coil into position. Please be careful not to break the electrical connector.
3. Complete the Campaign Completion Label
In the United States and Canada, vehicles repaired under the 28F2 emissions campaign (or this interim TSB) are required to be identified with a Campaign Completion Label.
1. Order labels at no cost from Archway Marketing Services (formerly Resolve Corporation). The part number is CAMP 010 000.
2. Fill out the Campaign Completion Label using SAGA Code 28F2.
3. Ensure the area next to the vehicle emission control label is clean.
4. Affix the Campaign Completion label next to the vehicle emission control label.
4. If other DTCs are also stored in the ECM data memory, or if the misfire condition is not corrected by the replacement of the ignition coils:
Diagnose the condition and perform necessary repairs with the use of Guided Fault Finding, the Repair Manual and applicable Technical Service Bulletins.
Tip: These additional repairs are not covered by this Technical Service Bulletin.
5. In the state of California only:
The California Air Resources Board and the Department of Motor Vehicles (DMV) require emissions-related campaigns to be completed prior to vehicle registration renewal.
1. When campaign work is done, provide the owner with a signed "Vehicle Emission Recall - Proof of Correction certificate (RC EMISCAVWAU). Certificates can be ordered at no cost from Archway Marketing Services (formerly Resolve Corporation).
2. Ensure owners are aware of the importance of retaining the completed certificate for their records. The certificate should be mailed to the California DMV only upon request.
