mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring

Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.

played on the CONSULT-II screen.

nosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a
correct unit can be checked by confirming this classification number on the CONSULT-II screen.
