What's wrong?
The ignition circuit on these 2023-2024 Altec Aerial Device, Digger Derrick, and Pressure Digger vehicles supplies switched electrical power to chassis and body equipment. The Advanced Signal Actuation Module, or ASAM, helps manage signals for added equipment on the Freightliner M2 chassis. That circuit is supposed to carry the accessory load without interrupting engine power.
On affected vehicles, certain aftermarket accessory setups put too much electrical load on the chassis ignition circuit. When multiple accessories are turned on at the same time, the ignition fuse can blow. Once that fuse opens, the engine shuts down because the ignition circuit no longer has power.
A periodic inspection and circuit load test can show whether the circuit is overloaded. There is no warning sign before failure other than that inspection finding, so the first thing an operator notices can be the blown fuse and engine shutdown.
Who's affected?
All listed Altec models use the same Advanced Signal Actuation Module in the electrical system.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included in this recall.
What's the safety risk?
An overloaded accessory circuit can blow a fuse and shut down the engine, increasing the risk of a crash. There is no warning before the fuse blows, so treat an included VIN as a reason to schedule the rewiring promptly. Repair is free at any franchised Altec dealer.
What should I do?
- Check your VIN to confirm your 2023-2024 Altec Aerial Device, Digger Derrick, or Pressure Digger is included in this recall.
- Contact a franchised Altec dealer to schedule the free accessory-circuit rewiring that prevents ignition-circuit overload, a blown fuse, and engine shutdown.
- Bring the owner letter if you have it. If not, reference recall number 24V681 when you call.
- Call Altec customer service at 1-877-462-5832 with questions about scheduling or vehicle operation before the repair.
- Drive cautiously until the repair is complete, and ask Altec before operating the vehicle if it has already shut down or blown the ignition fuse.
What happens at the repair
At the dealer, an Altec technician rewires the accessory circuit so the chassis ignition circuit is no longer overloaded. The recall repair is free, and parts and labor are covered. Altec's warranty policy also covers the recall remedy when an owner already paid to fix the same problem before the owner letter. If you have prior repair paperwork, contact Altec customer service and ask how to submit documentation for reimbursement.
