1. 

SELF-DIAGNOSTIC RESULT CHECK

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 carries out CAN communication.

1.

Connect to CONSULT-II, and select “BCM” on “SELECT SYSTEM” screen.

2.

Select “BCM ” on “SELECT TEST ITEM” screen, and select “SELF-DIAG RESULTS”.

3.

Check display content in self-diagnostic results.

Configuration

EKS00G0R

DESCRIPTION

CONFIGURATION has two functions as follows:

●

READ CONFIGURATION is the function to confirm vehicle configuration of current BCM.

●

WRITE CONFIGURATION is the function to write vehicle configuration on BCM.

CAUTION:

●

When replacing BCM, you must perform WRITE CONFIGURATION with CONSULT-II.

●

Complete the procedure of WRITE CONFIGURATION in order.

●

If you set incorrect WRITE CONFIGURATION, incidents will occur.

●

Configuration is different for each vehicle model. Confirm configuration of each vehicle model.

READ CONFIGURATION 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 carries out CAN communication.

1.

With ignition switch OFF, connect CONSULT-II and CONSULT-II
CONVERTER to data link connector and turn ignition switch ON.

2.

Touch “START (NISSAN BASED VHCL)”.
