Summary: Subject: Update – Campaign Warranty Claim Response Enhancements – Modules Not Repaired for Certain Campaigns Dear Mazda Dealer Colleagues, On October 28, 2026, a change was implemented in the warranty claim response screen to provide precise information for all campaigns requiring module programming or module replacement subject to the LECS system software checks. As previously announced, some claims were automatically rejected with the Edit code JN1 – One or More Modules Are Not Updated when submitting a campaign warranty claim. This response was based on the session file received from MDARS or MDARS II at the dealership and the VIN on the claim submitted. This change provides additional Related Information which enhances the edit code information. This information allows the dealer to correct the error without contacting Warranty or Hotline. Edit code JN1 now contains the actual module name and the software version that was collected from the car and what the minimum required software needed to be for the claim. Using this information, the technician can now identify the exact error or errors and correct the concern.
