What's wrong?
The ABS fuse on the 2019-2022 Oshkosh S-Series feeds and protects the anti-lock brake system circuit. ABS helps keep the wheels from locking during hard braking by controlling brake pressure at the wheels. The fuse is supposed to let the required current reach that system, then open only when the circuit needs protection.
On affected S-Series trucks, Oshkosh found 10 amp fuses installed where 15 amp fuses were required. The smaller fuse is not adequate for a full ABS braking stop. If it blows during that kind of stop, the ABS circuit loses power and the truck no longer has anti-lock brake assistance for that braking event.
If the fuse is blown, the instrument cluster shows an ABS fault light. That light is the warning sign that the ABS fuse has failed. The recall repair replaces the incorrect fuse with a 15 amp fuse and updates the fuse label so future replacements use the correct rating.
Who's affected?
Spans the same S-Series truck line across four model years, with wiring listed as the affected component for each year.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An incorrectly sized fuse can blow during an ABS braking event, which disables ABS support and increases the risk of a crash. If the ABS fault light appears on the cluster, treat it as a warning sign and schedule the recall repair soon. Repair is free at any franchised Oshkosh dealer.
What should I do?
- Check your VIN to confirm your 2019-2022 Oshkosh S-Series is included in this recall.
- Contact Oshkosh customer service at 1-888-686-7278 to get the free ABS fuse kit, fuse label, and installation instructions.
- Reference recall number 21V482 when you call so Oshkosh can match the request to the correct campaign.
- Replace the undersized ABS fuses with the free Oshkosh fuse kit that corrects the ABS fuse rating problem.
- Drive cautiously until the fuse repair is complete. Leave extra following distance and slow down before hard braking.
What happens at the repair
At the dealer, an Oshkosh technician replaces the incorrect 10 amp ABS fuses with the required 15 amp fuses, applies the new fuse label, and follows the Oshkosh installation instructions. Oshkosh is providing the fuses, label, and instructions free of charge, so parts and labor tied to the recall are covered. Out of pocket repairs already paid are handled through the normal warranty claim process, not through a separate reimbursement program. Ask the service desk how the warranty claim process applies if you already paid for an ABS fuse repair.
