What's wrong?
The front air bag system in these 2014-2015 E-One Quest, Typhoon, and Cyclone Ii emergency vehicles is built to help protect occupants during a crash. Sensors and control modules read crash forces, then send the electrical signal that deploys the front air bags when deployment is needed. That signal path depends on the wiring harness being fully plugged into the air bag control modules.
On affected vehicles, the harness for the front air bag system left production disconnected or not fully connected to the controllers. In that condition, the control modules do not have the proper connection to command the front air bags. The filing also describes temporary resistor packs found at the Master or Slave harness connectors, instead of the correct harness connection.
There is no warning sign before failure. The operator does not get a light or indicator showing that the air bag system is not working.

What should I do?
- Check your VIN to confirm your 2014-2015 E-One Quest, Typhoon, or Cyclone Ii is included in this recall.
- Contact a franchised E-One dealer to confirm the free front air bag harness inspection, connection, and system test are complete.
- Reference recall number 15V646 when you call, since E-One said no owner letter was issued after affected vehicles were repaired.
- Call E-One customer service at 1-800-627-5050 with questions about the repair status.
- Confirm the front air bag system test passed before returning the emergency vehicle to regular service.
What happens at the repair
At the dealer, an E-One technician inspects the front air bag system harness, connects it as needed, and tests the air bag system for proper operation. The inspection, connection work, testing, parts, and labor are free under the recall. E-One's filing says all affected vehicles have been repaired, so no owner notification letter was issued for this campaign. If you already paid for recall-related air bag harness work before the repair, E-One's general reimbursement plan covers eligible documented expenses. Bring the repair paperwork to the service desk.
