In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 1% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
1. Inspect 276-1242 4 pin engine harness connector and check the connector locking tab for proper engagement with injector harness receptacle. Image 1 is a damaged locking tab. Image 2 is a good locking tab. If locking tab is found to be damage proceed with replacement.
2. Disconnect the 276-1242 4 pin engine harness connector from the 113-4630 injector harness receptacle at the cylinder head.
3. Remove and replace 276-1242 4 pin connector with new. Insure to reinstall 4C-6389 heat shrink on the connector.
4. Inspect the inside of 113-4630 injector harness receptacle mounted on cylinder head for debris, damage, or paint. If debris, damage, or paint is present, remove and replace 113-4630 injector harness receptacle with new.
Note: Always use a new valve cover gasket if removal of valve cover is required.
5. Reconnect new 276-1242 4 pin engine harness connector to the new 113-4630 injector harnesses receptacle. Insure the connector is fully seated, audible click is heard, lock tab in the proper position, and connector cannot be pulled out.
