Electronic Control Unit Setup and ART Diagnostic References
The technician documentation includes All Round Tester (ART) references for connecting to the engine and electronic lift control units. The commissioning sections identify procedures for configuring the engine type, calibrating the hand throttle and accelerator pedal, setting engine idle speed, selecting HML and preheating configurations, and calibrating maximum hydraulic lift height.
Dedicated alarm and test meter sections provide references for engine and lift control fault indications, controller monitoring, sensor testing and calibration. The electrical diagrams further distinguish mechanical and electronic governor configurations, including separate engine wiring references for three-cylinder and four-cylinder versions.
