Defect
On hybrid transit buses, the electric clutch actuator that controls clutch engagement was improperly manufactured, resulting in units installed with a deformed internal control circuit board. Repeated thermal expansion and contraction of the CPU terminal solder joints causes cracks to develop at those joints. This causes the warning lamp to illuminate and the system to enter a fail-safe mode, preventing the clutch from engaging or disengaging. In the worst case, the engine may stall while driving, rendering the vehicle inoperable.
Corrective action
On all vehicles, replace the electric clutch actuator with a corrected part.
