DTC B150A Lost Communication with HMI-LAN


DESCRIPTION

  1. *1: w/ Navigation System
  2. *2: w/ Audio and Display System
The combination meter assembly receives a text data signal from the multi-media module receiver assembly*1 or radio and display receiver assembly*2 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.
DTC Detection Condition
Trouble Area
B150A
After the combination meter assembly receives a registration information signal, which is sent by the multi-media module receiver assembly when the ignition switch is turned ACC, 1 or more times, the combination meter assembly does not receive the signal for 30 seconds or more.

    Tester Connection
    		Condition
    		Specified Condition
    E119-37 (MSCH) - F77-1 (CANH)
    		Always
    		Below 1 Ω
    E119-38 (MSCL) - F77-2 (CANL)
    		Always
    		Below 1 Ω
    E119-37 (MSCH) or F77-1 (CANH) - Body ground
    		Always
    		10 kΩ or higher
    E119-38 (MSCL) or F77-2 (CANL) - Body ground
    		Always
    		10 kΩ or higher
    Standard Resistance (for RHD):
    Tester Connection
    		Condition
    		Specified Condition
    E119-37 (MSCH) - F77-20 (CAH2)
    		Always
    		Below 1 Ω
    E119-38 (MSCL) - F77-21 (CAL2)
    		Always
    		Below 1 Ω
    E119-37 (MSCH) or F77-20 (CAH2) - Body ground
    		Always
    		10 kΩ or higher
    E119-38 (MSCL) or F77-21 (CAL2) - Body ground
    		Always
    		10 kΩ or higher
