Cummins is recalling 33 Electric Drivetrains, part number PD7000.
The electric drive train cannot detect isolation faults when the high voltage contactors are closed.
An undetected high voltage isolation can expose service personnel to high voltage, increasing the risk of injury.
What to do
Cummins will notify owners, and dealers will update the Vehicle Control Unit software or install a different combination of High Voltage Power Distribution Unit hardware free of charge.
The manufacturer has not yet provided a schedule for recall notification.
Owners may contact Cummins customer service at (800) 286-6467.
