What's wrong?
The high voltage positive cable on 2022-2023 Ic Bus EV school buses carries power from the battery packs to the manual service disconnects. A manual service disconnect is the service point used to isolate battery power before work is done on the electric propulsion system. The cable and its labels need to identify the correct isolation level so service staff know what they are handling.
On affected buses, the cable was built with the wrong identification marking tape and warning labels. The design changed to use remote mounted manual service disconnects, but the cable color was not changed with it. The recalled cable was marked as level 2 isolation with blue tape, when it needed level 3 isolation marking with white tape.
This is a labeling and identification problem, not a warning-light problem for the driver. There is no warning sign before failure.
Who's affected?
Covers the 2022 and 2023 model years for the EV, with the same electric propulsion system component involved in each year.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
A misidentified electrical cable can lead a technician or first responder to treat an energized cable as safe, increasing the risk of electrical shock and injury. There is no owner warning sign for this labeling problem, so schedule the repair soon and tell service personnel the EV is under recall 22V850. Repair is free at any franchised Ic Bus dealer.

What happens at the repair
At the dealer, an Ic Bus technician reinstalls the high voltage positive battery cables that connect the battery packs to the manual service disconnects, then replaces the related warning labels. The recall repair is free, with parts and labor covered. If you paid for this cable or label repair before the owner notice, Navistar's reimbursement plan applies.
