DTC 15-3: Faulty OPDS Sensor
1. Erase the DTC memory {see page 23-261.
2. Turn the ignition switch ON (ll), and check that the
SRS indicator comes on for about 6 seconds and
then goes off.
Does the SRS indicator stay on?
YES-Go to step 3.
NO Intermittent failure, system is OK at this time.
Go to Troubleshooting Intermittent Failures (see
page 23-26).
NOTE: Aftermarket devices (fluorescent lights,
laptop computers, etc.) used near the front
passenger's seat-back can interfere with the seat-
back sensors and cause a false DTC 15-3. lf one of
these devices was used, erase the DTC, operate the
device near the seat-back, and recheck for DTCs. lf
DTC 15-3 is reset, erase it, and do not use the
device near the seat-back.

Component Replacement/lnspection After Deployment
NOTE: Before doing any SRS repairs. use the PGM
Tester SRS menu method to check for DTCS; refer to the
DTC Troubleshooting Index for the less obvious
deployed parts (seat beit tensioners, front sensors, side
airbag sensors, etc.)
After a collision where the seat belt tensioners
deployed, replace these items:' Seat belt tensioners. Seat belt buckle tensioners. SRS unit. Front impact sensors
After a collision where the front airbag(s) deployed.
replace these items:. SRS unit. Deployed airbag(s). Seat belt tensioners. Seat belt buckle tensioners. Front impact sensors
After a collision where the side airbag{s) deployed,
replace these items:. SRS unit. Deployed side airbag(s). Side impact senso(s)for the side(s) that deployed
During the repair process, inspect these areas:
. lnspect allthe SRS wire harnesses. Replace, don't
repair, any damaged harnesses.. Inspectthecable reelfor heatdamage. lf there is any
damage, replace the cable reel.
Afterthe vehicle is completely repaired, turn the
ignition switch ON (ll). lf the SRS indicator comes on for
about 6 seconds and then goes off, the SRS airbag
system is OK. lf the indicator does not function properly,
use the PGM Tester SRS Menu Method to read the DTC
(see page 23-23). lf this doesn't retrieve any codes, use
the Tester's SCS menu method (see page 23-24). lf you
still cannot retrieve a code, go to SRS Indicator Circuit
Troubleshooting.

9. Cut off each connector, strip the ends of the wires,
and connect the deployment tool alligator clips (A)
to the wires. Place the deployment tool at least 30
feet (10 meters) away from the vehicle.
NOTE: The driver's airbag and the front passenger's
airbag each have four wires, two yellow and two
red. Twist each Dair of unlike colored wires
together, and connect an alligator clip to each pair.

10. Connect a 12 volt battery to the tool.
. lf the green light on the tool comes on, the igniter
circuit is defective and cannot deDlov the
component. Go to Disposal of Damaged
ComDonents.. lf the red light on the tool comes on, the
component is ready to be deployed.
11. Push the tool's deployment switch. The airbags and
tensioners should deploy (deployment is both
highly audible and visible: a loud noise and rapid
inflation of the bag, followed by slow deflation).
. lf the components deploy and the green light on
the tool comes on, continue with this procedure.
. lf a component doesn't deploy, yet the green
light comes on, its igniter is defective. Go to
Disposal of Damaged components.. During deployment, the airbags can become hot
enough to burn you. Wait 30 minutes after
deployment before touching the airbags.
12. Dispose ofthe complete airbag. No pan of it can be
reused. Place it in a sturdy plastic bag (A), and seal
rt securery.
