Pre-Start System Check with Cat ET:
Before starting the engine, connect the Caterpillar Electronic Technician (ET) diagnostic tool.
Turn the key to the ON position. Use Cat ET to check for active diagnostic codes, particularly communication errors (e.g., CAN bus failures). Check that all connected ECMs are recognized.

Functional Test:
Start the engine and let it idle. Monitor for any abnormal warning lights.
Perform a low-speed operational check in a safe area, testing basic steering and transmission functions.
A full functional test of all systems (implements, braking, etc.) should be conducted to ensure complete integration.
