Ic Bus is recalling 9 2019 Cesb school buses because an air supply line for the SR7 roll stability valve was routed to the wrong ATR6 brake control valve port.

What's wrong?
The 2019 Ic Bus Cesb uses an air brake system with ABS and electronic stability protection. ABS helps prevent wheel lockup, and the stability system uses valves and air lines to help manage braking when the bus starts to roll or lose stability. The SR7 roll stability valve is part of that air-controlled system.
On affected buses, the air supply line for the SR7 roll stability valve was connected to the ATR6 brake control valve steer axle delivery port instead of the control port. The control port tells the valve when to act. The delivery port sends brake air toward the steer axle. Navistar traced the problem to an engineering assembly drawing that did not match the brake schematic, so the line was routed to the wrong place during assembly.
There is no warning sign before failure. The driver should not expect a light, sound, pedal change, or other signal that the air line is routed incorrectly.

What's the safety risk?
In slippery road conditions, a stability control oversteer event can unintentionally modulate the parking brakes, leading to loss of control and increased crash risk. There is no warning sign before this issue. Drive cautiously in slippery conditions and schedule the recall repair soon. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2019 Ic Bus Cesb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free air-line rerouting that connects the SR7 roll stability valve supply line to the ATR6 brake control valve control port.
- Bring the recall notice if you have it, and reference recall number 18V290 when you call.
- Drive with extra care on slippery roads until the repair is complete, because the parking brakes can apply unintentionally during a stability-control oversteer event.
What happens at the repair
At the dealer, an Ic Bus technician reroutes the SR7 roll stability valve supply line from the ATR6 brake control valve steer axle delivery port to the ATR6 brake control valve control port. The recall repair is free, including parts and labor. The reimbursement plan for this campaign applies to qualifying repairs paid before the recall notice. Reimbursement instructions are included in the customer notification, so keep related repair documentation and follow the claim steps in that notice.
