Freightliner Cascadia steering wheel air bag replacement

Posted by: on

Symptoms

Steering wheel air bag codes, parts unavailable. 

Issue

Cascadia vehicles (not NEW Cascadia) experience shortages and future scarcity for for steering wheel air bag replacements resulting from the supplier transition from Takata to Joysen. 

Solution

Joysen now supplies Cascadia steering wheel airbags for many applications. The Joysen airbags are the same fit as the Takata versions, but the connector on the airbag squib to the clockspring is different. The clockspring must be replaced along with the updated Joysen airbag, and in some circumstances the crash sensor may need to be updated to match. Due to the additional parts necessary for steering wheel airbag replacement combined with potential parts scarcity, all proper troubleshooting steps must be taken proactively to avoid costly errors. 

Check the solutions below. Note in the document that the reader must first determine the applicable 725 module datacode that the vehicle was built with. This may require a call to either the dealership's respective DSM or the DTNA Customer Assistance Center. If the reader finds that the flowchart dead ends with "Contact Engineering", the final step is to contact the DTNA Customer Assistance Center and request escalation via a Sales Force case. 

Additional note- the switches in  the new Joysen air bag covers do not have LED backlighting to match the original function. If the customer wants to retain the LED backlighting, and the original switches are in good order, the  Takata switch pod assembly can be swapped into the replacement Joysen part.
