  1. Inspect all four tires on the vehicle and note the size of each tire.
    NOTE:

    A non-production size tire cannot be programmed into the BCM. The production Powertrain, with the production size tires, is the only emissions certified configuration that is available for reprogramming.

  2. Verify the correct Tire/wheel information is programmed in the BCM.

    Is the correct value programmed in the BCM according to the chart?

    Yes 

    No 

    • Program the correct Tire/Wheel information in the BCM.
    • Perform the DTCM VERIFICATION TEST. Refer to DTCM VERIFICATION TEST  .
