Missing EGR throttle valve CAN message; CANTransmit-Frame ComEGRTVActr timeout error; (missing CAN Bus message) timeout error

Missing message of EGR throttle valve; timeout error of CAN-Receive-Frame ComRxEGRTVActr; timeout error (missing CAN Bus message)

0Start interlock fault

Start interlock switches not closed. Seat switch, Restraint bar switches and/or front door switch are not closed when the engine is not running

Engine will not start

Check wiring connections on seat, restraint bar and front door (if equipped) switches

Check switch-to-magnet alignment on restraint bar and front door proximity switches

If not equipped with a front door, check for the presence of the switch jumper on ROPS harness C2 dropout
