System Description
NLBR0226
CAN (Controller Area Network) is a serial communication line for
real time application. It is an on-vehicle multiplex communication
line with high data communication speed and excellent error detec-
tion ability. Many electronic control units are equipped onto a
vehicle, and each control unit shares information and links with
other control units during operation (not independent). In CAN
communication, control units are connected with 2 communication
lines (CAN H line, CAN L line) allowing a high rate of information
transmission with less wiring. Each control unit transmits/receives
data but selectively reads required data only.

SELF-DIAGNOSIS
NLBR0210S02
Operation Procedure
1.
After obtaining customer’s information, perform BR-70, “Basic
inspection”.
MBIB0906E
2.
After turning ignition switch OFF, connect CONSULT-II connec-
tor to data link connector on vehicle.
3.
Start engine and drive at Approx. 30 km/h (19 MPH) for
Approx. 1 minute.
MBIB0233E
4.
Stop vehicle. With engine at idle, touch “START (NISSAN
BASED VHCL)”, “ABS” and “SELF-DIAG RESULTS” on CON-
SULT-II screen in this order.
CAUTION:
“ABS” may not be displayed on the system selection screen
in the following case: When “START (NISSAN BASED VHCL)”
was touched just after engine is started or ignition switch is
turned to ON. In this case, repeat procedure from step 2.
5.
Self-diagnosis result is displayed. (If necessary, touch “PRINT”
to print self-diagnosis result.)

LAMP INSPECTION”.
6.
Check the faulty part indicated by the chart to repair or replace.
7.
Start engine and drive at Approx. 30 km/h (19 MPH) for
Approx. 1 minute.
CAUTION:
I
Check again to make sure that there is NO FAILURE on
other parts.
I
If wheel sensor [SHORT] is detected, ABS warning lamp
does not turn off until following conditions: Vehicle is
driven at Approx. 30 km/h (19 MPH) for Approx. 1 minute,
even in normal conditions.
8.
Turn OFF ignition switch to prepare for erasing memory.
9.
Start engine. Touch “START (NISSAN BASED VHCL)”, “ABS”,
“SELF-DIAG RESULTS” and “ERASE MEMORY” on CON-
SULT-II screen in this order to erase fault memory.
CAUTION:
If memory cannot be erased, proceed to 6.
10. Drive at Approx. 30 km/h (19 MPH) for Approx. 1 minute. Be
sure ABS warning lamp is OFF.
