12. Measure the resistance between rear safing sensor
4P connector terminal No. 3 and body ground.
There should be an open circuit or at least 1 M .
Go to step 13.
Short to ground in the floor wire harness;
replace the floor wire harness, then clear the
DTC.
13. Turn the ignition switch to ON (II).
14. Measure the voltage between rear safing sensor 4P connector terminal No. 2 and body ground. There
should be less than 0.2 V.
Go to step 15.
Short to power in the floor wire harness;
replace the floor wire harness, then clear the
DTC. 15. Measure the voltage between rear safing sensor 4P
connector terminal No. 3 and body ground. There
should be less than 0.2 V.
Go to step 16.
Short to power in the floor wire harness;
replace the floor wire harness, then clear the
DTC.
16. Turn the ignition switch to LOCK (0).
17. Connect the SRS inflator simulator (jumper connector) and the red lead of simulator lead L to
the floor wire harness 4P connector (A) at the left
side impact sensor (first).

18. Measure the resistance between rear safing sensor
4P connector terminal No. 2 and No. 3. There
should be less than 1.0 .
Faulty rear safing sensor or poor connection
at the floor wire harness 4P connector and the rear
safing sensor. Check the connection between the
connector and the rear safing sensor. If the
connection is OK, replace the rear safing sensor
(see page 24-206), then clear the DTC.
Open in the floor wire harness; replace the
floor wire harness, then clear the DTC. NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13) and General Troubleshooting Information
(see page 24-22).
1. Clear the DTC memory (see page 24-23).
2. Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
Replace the rear safing sensor (see page
24-206), then clear the DTC. If the DTC returns,
replace the SRS unit (see page 24-203).
Intermittent failure, system is OK at this time.
Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC.

Symptom Troubleshooting (cont’d)
NOTE: Under the following conditions, the passenger’s
airbag cutoff indicator stays on or comes on suddenly.
 No one is sitting the front passenger’s seat, but there is an object on the seat more than 5 kg (11 lbs).
 The seat belt is buckled, but no one is sitting on the front passenger’s seat.
 Someone who is less than 30 kg (66 lbs) is sitting on the front passenger’s seat.
 Someone who is more than 30 kg (66 lbs) but is supporting some of their body weight on their legs,
feet, arms, or hands.
1. Check for these items, then recheck the passenger’s airbag cutoff indicator.
 The front passenger’s seat is/was installed correctly.
 Nothing is/was on the front passenger’s seat.
 Nothing is/was under the front passenger’s seat.
 Nothing is/was in the front passenger’s seat-back pocket.
 Whoever was sitting on the passenger’s seat was sitting in the proper sitting position.
Go to step 2.
Troubleshooting is complete.
2. Connect the HDS to the data link connector (DLC) (see page 24-22).
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).5. Select the INSPECTION menu on the HDS, then
select AFTER REPLACING FRONT PASSENGER’S
SEAT COMPONENT(S), and follow the prompts.
Go to step 6.
Troubleshooting is complete.
6. Select the INSPECTION menu on the HDS, then select AFTER A VEHICLE COLLISION, and follow
the prompts.
Replace the SRS unit (see page 24-203). If the
problem is still present, replace the ODS unit
(see page 24-209), and then if the problem is still
present, replace the passenger’s weight sensors
(see page 24-207).
Troubleshooting is complete.
