TROUBLE DIAGNOSIS

2005 Pathfinder

NOTE:
Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunction is
eliminated using air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is still
observed, proceed to the next step. When malfunction is eliminated, further repair work is not required.

DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-II—Diagnosis Mode

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
in self-diagnosis depending on control unit which carry out CAN communication.

After repairing SRS, connect both battery cables.

Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.

Turn ignition switch ON.

Touch “START (NISSAN BASED VHCL)”.

Touch “AIR BAG”.

connection.

2. Replace the harness if it has visible

damage.

3. Replace RH front seat belt assem-

bly.

4. Replace RH front seat cushion/

occupant classification system con-
trol unit assembly.

PASS A/B INDCTR CKT

If "AIR BAG" is not indicated, refer to

GI-38, "CONSULT-II Data

Link Connector (DLC) Circuit"

Touch “SELF-DIAG [CURRENT]”.

If no malfunction is detected on “SELF-DIAG [CURRENT]”,
repair of SRS is completed. Go to step 8.
If any malfunction is detected on “SELF-DIAG [CURRENT]”, the
malfunctioning part is not repaired completely or another mal-
functioning part is detected. Go to

SRS-23, "DIAGNOSTIC

PROCEDURE 2"

, and repair malfunctioning part completely.

Touch “ERASE”.

NOTE:
Touch “ERASE” to clear the memory of the malfunction
(“SELF-DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [PAST]” is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is repaired
completely.

Touch “BACK” key of CONSULT-II to “SELECT DIAG MODE”
screen. Touch “SELF-DIAG [PAST]”.
