BYD ATTO 3 (e-Platform 3.0) U0245 Instrument And Multimedia Communication Interrupt

U0245 indicates that communication between the instrument cluster and multimedia system has been interrupted. The fault affects the vehicle’s electronic communication network, which exchanges information between the instrument cluster, infotainment system, and associated control modules for displaying and managing vehicle and multimedia functions. The BYD ATTO 3 uses BYD’s e-Platform 3.0 architecture, with this generation introduced from 2022 and continuing onward.

Symptoms

• Instrument cluster may display missing or incorrect multimedia information
• Multimedia information may not appear correctly on the instrument display
• Infotainment functions may operate intermittently
• Instrument cluster or multimedia system may restart
• Communication warning may be displayed
• Some vehicle or media information may be unavailable
• Multiple communication-related fault codes may be stored
• U0245 stored in the relevant control system

Possible Causes

• CAN communication wiring fault
• Open or short circuit in the communication network
• Loose or damaged instrument cluster connector
• Loose or damaged multimedia system connector
• Poor connector terminal contact
• Corroded or damaged wiring
• Instrument cluster power or ground fault
• Multimedia system power or ground fault
• Low or unstable 12V auxiliary voltage
• Internal instrument cluster failure
• Internal multimedia control-module failure
• Another control module disrupting network communication
• Software or configuration fault

Diagnosis

Diagnosis should begin by confirming U0245 and performing a complete vehicle network scan for additional communication, power, and module-related faults. Instrument cluster and multimedia-system power and ground circuits, communication lines, connector condition, module availability, and network status should then be assessed against manufacturer specifications.

The diagnostic direction should determine whether the interruption originates from the instrument cluster, multimedia system, wiring, power supply, or another network module before either control unit is replaced.

Many independent workshops throughout New Zealand rely on OEM diagnostic information to verify communication faults before replacing electronic control modules.

Accurately diagnosing this fault often requires manufacturer testing procedures, wiring diagrams, connector pinouts, specifications, and system calibration information. Access to the factory service manual significantly reduces diagnostic time and helps prevent unnecessary parts replacement.
