The emission label is designed to be removed in pieces. After replacement, the removed label must be attached to
the certified emission label check sheet. Attach an image of the filled-out check sheet, with the removed label, to
the warranty claim. Refer to Work Instructions for further direction.

IMPORTANT - After Repair is Complete:

attaching the completion sticker.

If a campaign kit is not required, write the campaign number on a blank sticker and attach it to the base label.
(Failure to install a completion sticker may result in a chargeback of the campaign claim.)

Work Instructions

IMPORTANT: Owners of vehicles have been instructed to contact the dealership in advance to have the Emission
Certification Label ordered so it will be available when they arrive for the campaign. See Certified Emission Label

Ordering Instructions on page 19.

Corrective Procedure

1. Apply the parking brake, chock the wheels, and perform any other applicable safety steps.

2. Begin the process by connecting DiagnosticLink® version 8.21 (or a higher version) to the vehicle. Make sure
that all the powertrain modules (Motor Control Module (MCM), Common Powertrain Controller (CPC),
Aftertreatment Control Module (ACM), and Transmission Control Module (TCM) if applicable) are connected.

BEFORE beginning reprogramming, make sure the VIN is correct in all modules (ACM, CPC, and MCM). If the
VIN is not correct in all modules, an error message will be received when attempting to reprogram.

3. Make sure the VIN is correct in all powertrain modules by looking at the ‘Identification’ screen in
DiagnosticLink®. If the VIN is not correct in all modules, you can correct the VIN under the ‘Actions’ drop-down
menu, then selecting the ‘Check VIN Synchronization’ item. Select ‘Start’ from this panel and follow the
prompts. You will be prompted to cycle the keyswitch until the routine has completed. When synchronization is
complete, turn the keyswitch back ON (key ON, engine OFF) and continue with the download process.
