What's wrong?
The body control module, or BCM, on the 2020 Ic Bus Cesb school bus is an electronic control unit that sends commands to body and ignition circuits. In this recall, the C7 BCM feeds the starter solenoid, the electrical switch that tells the starter motor to crank the engine. That starter command is supposed to happen only when the key is turned to the crank position.
On affected buses, electrical overload from the PSI gasoline or propane engine starter solenoid can damage the BCM starter circuit. Once damaged, the circuit can stay active when the ignition key is in the run position. If the transmission is in park or neutral, the bus can receive an unintended engine crank command. The repair adds a relay and fuse so the BCM no longer powers the starter solenoid directly.
There is no warning sign before failure. A driver or technician should not expect a warning light, noise, or change in starting behavior before the unwanted crank command.
Who's affected?
The affected component list includes both ignition-module and starter-assembly items for the same Cesb bus model.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
The safety risk is tied to service work. If the ignition is in the run position and the engine starts unexpectedly during service, a person near the bus faces increased injury risk. There is no warning sign before this happens, so tell the service desk about recall 19V534 before repair work begins. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2020 Ic Bus Cesb is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free overlay-harness and relay installation.
- Tell the dealer the repair moves starter-circuit power away from the BCM to stop unintended cranking during service.
- Bring the recall notice if Ic Bus mailed one. If not, reference recall number 19V534 and Ic Bus recall 19512 when you call.
- Keep service work controlled by a qualified technician until the repair is complete.
What happens at the repair
At the dealer, an Ic Bus technician installs an overlay harness and relay so the starter circuit gets electrical power without relying on the body control module. The recall repair is free, including parts and labor. If you already paid out of pocket for this starter circuit repair before the recall notice, Navistar's standard reimbursement plan applies. Follow the reimbursement instructions in the customer notification and bring repair documentation to the service desk.
