Is there battery voltage?

YES - Open in the right side wire harness; replace the right side wire harness.

NO - Open in the dashboard wire harness A; replace dashboard wire harness A.

13. Turn the ignition switch OFF.

14. Measure the resistance between the No. 6 terminal of the front passenger's weight sensor unit 6P

Is the resistance as specified?

YES - Go to step 15.

NO - Open in the right side wire harness; check for poor ground connection at G651 (see RIGHT
SIDE WIRE HARNESS (FRONT BRANCH) ). If the connection is OK, replace the right side wire
harness.

15. Disconnect the negative cable from the battery, then wait for 3 minutes.

16. Disconnect SRS unit connector A (28P) from the SRS unit (see step 7 ). Disconnect OPDS unit 8P

connector from the OPDS unit (see OPDS UNIT REPLACEMENT ).

17. Measure the resistance between the No. 14 terminal of SRS unit connector A (28P) and body ground.

There should be an open circuit or at least 1 Mohms.

Is the resistance as specified?

YES - Faulty front passenger's weight sensor unit or SRS unit; replace the front passenger's weight
sensor unit (see FRONT PASSENGER'S WEIGHT SENSOR UNIT REPLACEMENT ). If the
problem is still present, replace the SRS unit (see SRS UNIT REPLACEMENT ).

NO - Go to step 19.

19. Disconnect left side wire harness 16P connector C604 (A) from the right side wire harness C604 (B).
