Product Description

5715400448 80B Combination Instrument Dashboard is installed inside the heavy truck cab dashboard assembly to provide real-time monitoring of engine operation, fuel level, vehicle speed, warning alarms, air pressure, temperature, and electrical system status.

Circuit board aging, unstable CAN communication, damaged display modules, or connector oxidation may cause inaccurate gauge readings, black screen issues, warning light failure, startup communication errors, and abnormal dashboard operation.

This dashboard assembly is widely used in export fleet maintenance, engineering vehicle electrical repair, commercial truck overhaul, and heavy truck aftermarket service.
