Maintenance Tips

• Keep the HD Add-On Module firmware and diagnostic software updated to maintain compatibility with the latest heavy-duty vehicle systems and protocols.
• Store the module, adapters, and cables in a clean, dry environment to protect connectors and electronic components.
• Inspect HD diagnostic connectors and adapter cables regularly for bent pins, corrosion, or physical damage.
• Clean connectors with a soft, dry cloth and keep dust, grease, and moisture away from communication ports.
• Use proper 12V or 24V vehicle power sources and verify battery voltage before performing diagnostics to avoid communication interruptions.
• Disconnect cables by gripping the connector body rather than pulling on the cable to prevent wiring damage.
• Check Bluetooth or wired communication settings periodically to ensure stable connections during diagnostic sessions.
• Organize and protect included HD adapters to prevent loss and ensure quick access for different truck and equipment brands.
• Perform routine inspections of the module housing and connectors after field use in harsh shop or fleet environments.
• Back up diagnostic reports and service data regularly to maintain accurate maintenance records.
