CONSULT-II SETTING 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 performs CAN communication.

●

For details, refer to the separate “CONSULT-II Operations Man-
ual”.

1.

Turn ignition switch OFF.

2.

Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector, which is located in instrument lower panel on
driver side.

3.

Turn ignition switch ON. (Do not start engine.)

4.

Touch “START (NISSAN BASED VHCL)”. 

5.

Touch “TRANSMISSION”.
If “TRANSMISSION” is not indicated, go to 

GI-39, "CONSULT-II

Data Link Connector (DLC) Circuit"

 .

6.

Perform each diagnostic test mode according to each service
procedure.

Set “ENGINE BRAKE LEVEL” by touching “UP” or “DOWN”.

6.

Turn ignition switch OFF, wait at least 5 seconds and then turn
ignition switch ON.

7.

Engine brake level set is completed.

CAUTION:

Mode of “+1” “0” “-1” “-2” “OFF” can be selected by press-
ing the “UP” “DOWN” on CONSULT-II screen. However, do not select mode other than “0” and
“OFF”. If the “+1” or “-1” or “-2” is selected, that might cause the irregular driveability.
