METER / GAUGE SYSTEM, Diagnostic DTC:B150A

DTC Code DTC Name
B150A Lost Communication with HMI-LAN

DESCRIPTION

The combination meter assembly receives a text data signal from the radio receiver assembly via local bus communication.

Based on this signal, audio and visual system or navigation system information is displayed on the multi-information display.

This DTC is stored when the combination meter assembly cannot receive the signal.

DTC No. Detection Item DTC Detection Condition Trouble Area
B150A Lost Communication with HMI-LAN After the combination meter assembly receives a registration information signal, which is sent by the radio receiver assembly when the power switch is on (ACC), 1 or more times, the combination meter assembly cannot receive the signal for 30 seconds or more.

  • Harness or connector

  • Radio receiver assembly

  • Combination meter assembly
