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.
1.
After repairing SRS, connect both battery cables.
2.
Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector.
3.
Turn ignition switch ON.
4.
Touch “START (NISSAN BASED VHCL)”.
5.
Touch “AIR BAG”.
BELT TENSION SENS
[UNIT FAIL]
[B1019]
●
Belt tension sensor is malfunctioning.
1. Visually check the wiring harness
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
[B1023]
●
