Final Secure and Visual Inspection:
Go back and tighten all P-clamps and brackets to the specified torque. Ensure the harness is secure but not stretched or pinched against any sharp edges.
Perform a meticulous visual check of the entire route. Look for any potential interference.
Reconnect the Batteries.
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.
