Diagnosis by History of Error
When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunction,
turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or delete
“History of Error”). Check “History of Error” again after the malfunction was reproduced, and then perform
diagnosis focusing on the item of which number of time increased.

detected.Replace display control unit.
Display Connect Error

Display power supply and ground
circuit malfunction is detected.

Malfunction is detected on commu-
nication signal between display con-
trol unit and display.1. Delete the “History of Error”, and turn
OFF ignition switch.
