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.

Operation Procedure

NLBR0210S0201

After obtaining customer’s information, perform BR-70, “Basic
inspection”.

MBIB0906E

After turning ignition switch OFF, connect CONSULT-II connec-
tor to data link connector on vehicle.

Start engine and drive at Approx. 30 km/h (19 MPH) for
Approx. 1 minute.

MBIB0233E

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.)

If “NO MALFUNCTION” is displayed, check ABS warning

lamp. Refer to BR-71, “BASIC INSPECTION 3 ABS WARNING
LAMP INSPECTION”.

Check the faulty part indicated by the chart to repair or replace.

Start engine and drive at Approx. 30 km/h (19 MPH) for
Approx. 1 minute.

CAUTION:

Check again to make sure that there is NO FAILURE on
other parts.

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.

Turn OFF ignition switch to prepare for erasing memory.

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.
