What's wrong?
The high voltage disconnect switch on 2022-2027 Ic Bus Evsb school buses is supposed to isolate the electric drive system from the traction battery. Think of it as the service shutoff point: when a technician turns the switch to Off, battery power should stop feeding the high voltage distribution module that sends power through the bus.
On affected buses, the High Voltage Disconnect Connector can be left unconnected while a bypass circuit still feeds that distribution module. That means the switch position says Off, but the high voltage system remains powered. International traced the condition to shorting bars inside the HVDC bypass connector; the repair removes those bars so an open connector no longer keeps the circuit energized.
The warning sign is an error message on the instrument cluster. If that message appears after service or while the bus is being checked, treat it as a sign that the high voltage disconnect system needs dealer attention.

What's the safety risk?
Switch failure can leave the high voltage battery energized while someone works on it, increasing the risk of injury or death by electrical shock. An instrument cluster error message is the warning sign; if it appears, stop service work and call the dealer before anyone works near the high voltage battery. Repair is free at any franchised Ic Bus dealer.
