Attention:	Mazda General Managers, Parts and Service Managers
Subject:	2015-2016 Mazda6 Occupant Classification System Harness Concern Safety Recall 1517H

On August 31, 2017, Mazda Motor Corporation decided to conduct a Safety Recall Campaign to address a concern with certain 2015-2016 Mazda6 vehicles.

Concern Outline:

On the front passenger seat, there may be excessive weld spatter on the seat frame. When the passenger seat is occupied, the occupant classification sensor (OCS) wire harnesses may contact the weld spatter due to up and down movement of the seat, and the harness insulation may be abraded over time. Eventually the harnesses may short-circuit, causing one or more of the following symptoms.

The possible concerns will depend on the harness(es) actually damaged.

EPAS warning light illumination with Loss of power steering assist
Air bag warning light illumination with Air bags deactivation
ABS/DSC warning light illumination (Braking function is maintained)
AFS/ADB warning light illumination (Lighting function is maintained) – Air conditioner malfunction
Others

Affected Vehicles:

Model	Subject VIN range	Subject production date range
2015-2016 Mazda6	JM1GJ15 F1 219009 – 225009 JM1GJ15 G1 400009 – 463163	From November 3, 2014 through December 9, 2015

Customer Notification:

Mazda will notify customer of affected vehicles by mail by late October 2017.

Additional details, including customer notification, parts and warranty information, and repair instructions, will be provided as soon as they are available on MGSS for your reference.

Subject:

Recall 1517H – 2015 & 2016 Mazda6 Occupant Classification Harness Stop Delivery Notification

On September 5^th, 2017 Mazda issued a recall notification for 1517H.

This notice is a stop delivery announcement for new and CPO vehicles involved in Safety Recall 1517H.

The subject vehicles must be grounded until they can be repaired. We apologize for the inconvenience and disruption to your sales and service business during this time. We are working closely to identify the impacts of this stop delivery on your business and on ways to accelerate removal of the stop delivery condition.

Affected VINs will be posted on MGSS as soon as they are identified and all affected VINs in this recall campaign will display “Not Launched” status in eMDCS Warranty Vehicle Inquiry on September 6^th, 2017. Only certain Mazda6 vehicles produced from November 3, 2014 through December 9, 2015 are affected.

If there are any questions please contact the Warranty Department at (877) 727-6626, Option 3.

Parts for this repair are expected to be available in approximately 10 days along with final repair and recall claim instructions. At that time, Mazda will communicate dealer support details for the stop delivery.

Concern Outline:

For certain 2015 and 2016 Mazda6 vehicles that may be in your New or CPO inventory, there is potential for the occupant classification sensor (OCS) wiring harness under the passenger seat becoming chafed and shorting out the CAN system.

MCVP Impact:

In addition to the stop delivery, we recognize that some dealers may have affected vehicles in their MCVP loaner fleet. These vehicles should be removed from loaner service immediately and quarantined until repairs can be completed. Dealers should place the vehicle in “maintenance” status in the TSD loaner fleet management software, open a repair order, and close the repair order when the recall is complete in order to earn the full utilization credit on any affected MCVP vehicles.

Thank you for your understanding and we will be back in contact next week with more details on this situation.
