Defect
On large touring hybrid buses, the vehicle control ECU software is incorrectly programmed. After the ABS activates and then deactivates, the ECU may, in rare cases, continue to register ABS as active. While the ECU remains in this erroneous state, operating the auxiliary brake has no effect and the auxiliary brake will not engage.
Corrective action
Reprogram the vehicle control ECU on all vehicles.
