What's wrong?
The ABS electronic control unit on 2021-2024 International trucks and buses is the computer that manages the anti-lock brake system. ABS watches wheel speed during braking and helps control brake pressure so the wheels keep turning instead of locking. The warning light is supposed to tell the driver when that system has a malfunction.
On affected vehicles, the ECU ABS-8 ROM 4.1 and 5.1 software sends a blink code command that interferes with the ABS lamp command on the vehicle network. When an ABS fault is active and the vehicle is moving, that interference turns the ABS indicator light off even though the fault still exists. The light comes back on when the vehicle stops.
The ABS light is not a reliable moving-vehicle warning in this defect. A fault in the ABS system also turns on the Traction Control and Stability Control indicator lamps, and those lights stay illuminated while the vehicle is in motion.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
An ABS indicator light that does not stay lit leaves the driver without that ABS malfunction warning, and crash risk rises. The Traction Control and Stability Control lamps stay illuminated while the vehicle is moving when the ABS system has a fault, so schedule the software update soon. Repair is free at any franchised International dealer.
What should I do?
- Check your VIN to confirm your 2021-2024 International Lonestar, Rh, Lt, Hx, Mv, Hv, Cesb, Ce, Emv, Tc, Re, or Recb is included in this recall.
- Contact a franchised International dealer to schedule the free software update that keeps the ABS warning light illuminated during a malfunction.
- Bring the recall notice if International mailed one. If not, reference recall number 23V370 (International recall 23515) when you call.
- Ask International customer service at 1-800-448-7825 if the dealer cannot confirm the campaign.
- Drive with extra spacing until the software update is complete, since the ABS warning light does not stay on during an ABS malfunction.
What happens at the repair
At the dealer, an International technician updates the brake system software so the ABS indicator light works as required when a malfunction exists. The software update is free under the recall, and parts and labor are covered. Towing-variant vehicles in this campaign are handled through this repair path instead of recall 24V-8918. If you paid for a related repair before the owner letter, Navistar's standard reimbursement plan applies. Keep your repair paperwork and follow the reimbursement instructions included with the customer notification.
