ENGINE SYSTEMS CONTINUED
Engine ECM Power Supply
The engine ECM and system draw power from the machine batteries. The power supply for the engine ECM
includes the following components:
Engine ECM connector
Machine interface connector
The engine ECM normally connects to battery voltage. The input from the ignition switch turns on the engine ECM.
The wiring harness can be bypassed for troubleshooting purposes.
Engine Air Cleaner
The air filter assembly mounts above the top of the engine and projects forward in the engine compartment. The
assembly contains primary and secondary filter elements.
Dry-type air cleaner elements filter the air before it flows into the inlet manifold of the turbocharger.
