Recall 10V003 affects 7 2009 Emergency One Cyclone Ii and Typhoon fire trucks for a faulty exhaust-regeneration inhibit switch. Repair will be free once available.
Emergency One is recalling 7 2009 Cyclone Ii and Typhoon fire trucks because the dash-mounted diesel particulate filter regeneration inhibit switch can fail to work as the operator expects. Hot exhaust gases can leave the tailpipe and increase the risk of burns or fire, and the dealer repair will be free once available.

What's wrong?
The 2009 Emergency One Cyclone Ii and Typhoon fire trucks use Cummins ISC CM2150 and ISL CM2150 diesel engines with an aftertreatment diesel particulate filter. That filter traps soot in the exhaust, then runs a regeneration cycle that burns the soot out. During regeneration, exhaust temperatures rise, so these trucks have a dash mounted inhibit switch the operator uses to stop regeneration when hot exhaust discharge is unsafe for the scene.
The defect is in the engine control module software logic, the computer that reads the switch and controls engine aftertreatment. On affected trucks, the hard wired inhibit switch does not function correctly. The switch can appear to be in inhibit mode while the computer still allows regeneration, so the operator has the wrong indication about what the exhaust system is doing.
There is no warning sign before failure. The owner or operator learns about the problem only when the switch indication and the actual regeneration behavior do not match.
Who's affected?
Covers the Cyclone Ii and Typhoon chassis from the same model year, both tied to the engine and engine cooling system.

A matching 2009 Emergency One Cyclone Ii or Typhoon truck does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Hot exhaust gases can exit the tailpipe and raise the risk of melting or burning nearby surfaces, burning people standing next to the tailpipe, or starting a fire. Keep people and combustible materials away from the tailpipe area and arrange recall service promptly. Repair will be free at any franchised Emergency One dealer once available.
What should I do?
- Check your VIN to confirm your 2009 Emergency One Cyclone Ii or Typhoon is included in this recall.
- Contact a franchised Emergency One dealer for current repair guidance before using the diesel particulate filter regeneration inhibit switch.
- Call Cummins at 1-800-343-7357 and ask about the ECM software repair that restores the inhibit switch function.
- Reference recall number 10V003 when you call the dealer or Cummins.
- Keep people and heat-sensitive surfaces away from the tailpipe until the repair is complete.
What happens at the repair
Emergency One is working with Cummins on the repair for the affected ISC CM2150 and ISL CM2150 diesel engines. Once the dealer repair is available, an Emergency One technician will repair the engine system tied to the dash mounted diesel particulate filter regeneration inhibit switch, free of charge. The goal is to correct the engine control logic so the operator's switch setting matches the truck's actual regeneration inhibit state.

Frequently asked questions
What is recall 10V003?
Recall 10V003 covers 7 2009 Emergency One Cyclone Ii and Typhoon fire trucks with Cummins ISC CM2150 or ISL CM2150 diesel engines. The dash switch for diesel particulate filter regeneration inhibit can give the operator the wrong status, allowing hot exhaust at the tailpipe. Emergency One is working with Cummins on a free repair.
What should I do if my 2009 Emergency One Cyclone Ii or Typhoon is on this recall?
Check your VIN to confirm your specific fire truck is included in recall 10V003. If it is, contact an Emergency One service dealer and reference recall 10V003. Cummins is also listed for repair support at 1-800-343-7357. The engine repair is free.
Is the recall repair free?
Yes. Federal recall law requires the safety defect repair at no cost to the owner. Emergency One is working with Cummins to repair the affected engines free of charge, so parts and labor for this recall are covered.
What is the safety risk in recall 10V003?
The risk is hot exhaust leaving the tailpipe when the operator believes regeneration inhibit is active. That heat can melt or burn nearby surfaces, injure people near the tailpipe, or start a fire. Confirm the VIN before relying on the dash switch status.
