The following functions are executed by combining data received and command transmitted via the communi-
cation line from the driver seat control unit.

*1: For setting seat functions only.
*2: Refer to

BL-109

.

CONSULT-II INSPECTION PROCEDURE

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.

Turn ignition switch “OFF”.

2.

Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector.
