cautionBefore replacing the multivision display ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
COMMENTS ON TROUBLE SYMPTOM
If the tail lamps illuminate, illumination signal is sent from the ETACS-ECU to the multivision display. This switches the illumination of the multivision display from day mode to night mode. If the mode is switched, the illumination signal line, the ETACS-ECU or the multivision display may be defective.
 
 
PROBABLE CAUSES
  • Malfunction of multivision display
  • Malfunction of ETACS-ECU
  • Damaged harness wires and connectors
