DAVIE4

DAVIE4 by PACCAR Inc. is an OEM diagnostic and programming platform designed for servicing PACCAR-powered commercial vehicles. It provides authorized technicians with tools to identify, troubleshoot, and resolve issues on PACCAR MX engines and related aftertreatment systems used in Kenworth and Peterbilt trucks (coverage varies by market and model year). The application offers guided diagnostics, secure ECU programming, and access to the data needed to minimize downtime and ensure repairs meet factory standards.

Key capabilities:

• Read and clear fault codes, view live sensor data, and record data logs
• Run bi-directional controls and functional tests (for example, DPF regeneration and cylinder cutout)
• Perform calibrations and parameter programming where permitted
• Apply ECU software updates and retrieve service information when connected to PACCAR systems
• Generate service reports and maintain traceable repair history

Notes:

• Requires an active PACCAR license/subscription and appropriate user credentials
• Runs on Windows and connects through a compatible vehicle communication interface (RP1210-compliant)
• Intended for authorized dealers, fleets, and qualified service providers, not for consumer use
