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.

REMOVAL
1. Operate wiper motor, and stop it at the auto stop position.
2. Remove cover wiper arm.
3. Remove wiper arm nut, and remove wiper arm from vehicle.
INSTALLATION
1. Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it “OFF” (auto stop).
2. Lift the blade up and then set it down onto glass surface to set
the blade center to clearance “L” immediately before tightening
nut.
