CONSULT-II FunctionsAKS007AG
CONSULT-II can display each diagnostic item using the following diagnostic test modes: work support, self-
diagnostic results, data monitor and active test through data reception and command transmission via the
BCM CAN communication line.
CONSULT-II OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn the
ignition switch ON.
