SWS (ODS unit) DTCs are subcodes of SRS unit DTCs.
Only troubleshoot the corresponding SRS DTCs.
Do the troubleshooting for SRS unit DTC 82-15, 82-17,
83-25, and 83-27 (see page 24-155). 1. Turn the ignition switch to LOCK (0), then wait for
10 seconds.
2. Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
Intermittent failure, system is OK at this
time.
Go to step 3.
3. Connect the HDS to the data link connector (DLC) (see page 24-22).
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. Do the gauge control module self-diagnostic function (see page 22-241).
Faulty SRS unit; replace the SRS unit
(see page 24-203).

Symptom Troubleshooting (cont’d)
SRS UNIT CONNECTOR A (28P)
NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13), General Troubleshooting Information (see page
24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68).
1. Connect the HDS to the data link connector (DLC) (see page 24-22).
2. Turn the ignition switch to ON (II).
3. 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).
4. Select Body Electrical status with the HDS.
5. Check for DTCs in the Gauge Menu with the HDS.
Go to the troubleshooting for DTC B 1187
(see page 22-265).
Go to step 6.
6. Check that the HDS communicates with the SRS unit.
Go to step 7.
If the HDS does not communicate with the
SRS unit, check for power and ground at the SRS
unit connector A (28P). If power and grounds are ok,
replace the SRS unit (see page 24-203).
7. From the HDS System Menu, select SRS, then SRS in Mode Menu, PARAMETER INFORMATION, then
SCS, MES, Indicator. Read the current status of the
SRS indicator.
Faulty SRS unit; replace the SRS unit
(see page 24-203).
Go to step 8. 8. Do the gauge self-diagnostic test (see page 22-241).
Go to step 9.
Faulty gauge control module (tach); replace
the gauge control module (tach) (see page 22-277).
9. Turn the ignition switch to LOCK (0). Disconnect the negative cable from the battery, and wait at least 3
minutes.
10. Disconnect the SRS unit connector A (28P) from the SRS unit (see step 8 on page 24-21).
11. Measure the resistance between SRS unit connector A (28P) terminal No. 5 and body ground.
There should be an open circuit or at least 1 M .
Faulty SRS unit or poor connection at SRS
unit connector A (28P) and the SRS unit. Check the
connection between the connector and the SRS
unit. If the connection is OK, replace the SRS unit
(see page 24-203).

Component Replacement/Inspection After Deployment
NOTE: Before doing any SRS repairs, check the SRS DTCs (see page 24-22) for the less obvious deployed
components (seat belt tensioners, front impact
sensors, side airbag sensors, etc.).
 After a vehicle collision, do the ODS unit operation check (see page 24-28).
 Do not replace the ODS unit unless it is physically damaged or a specific fault was found during DTC
troubleshooting.
 After a vehicle collision, inspect the front seat active head restraints (see page 20-117).
After a collision where the seat belt tensioners
deployed, replace these items:  SRS unit
 Seat belt tensioners
 Seat belt buckle tensioners
 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
 Side impact sensor(s) (first)
 Side impact sensor(s) (second)
 B-pillar lower trim
 Front seat assembly (Impact side) After a collision where a side curtain airbag deployed,
replace the items for the side(s) that deployed:
 SRS unit
 Deployed side curtain airbag(s)
 Seatbelttensioner(s)
 Side impact sensor(s) (first)
 Side impact sensor(s) (second)
 Rear safing sensor
 Roof trim

Component Replacement/Inspection After Deployment (cont’d)
During the repair process, inspect these areas:
 Inspect all the SRS wire harnesses. Replace, do not repair, any damaged harnesses.
 Inspect the cable reel for heat damage. If there is any damage, replace the cable reel.
After the vehicle is completely repaired, turn the
ignition switch to ON (II). If the SRS indicator comes on
for about 6 seconds and then goes off, the SRS is OK. If
the indicator does not function properly, use the HDS to
read the DTC (see page 24-22). If you cannot retrieve a
code, Do the SRS Symptom Troubleshooting.
Always replace.

EDGE OF HEADLINER
LESS THAN
15 mm (0.6 in.)
MASKING TAPE
To prevent the side curtain airbag from deploying and
damaging the pillar trim, the overlap between the
headliner and pillar trim must be less then 15 mm
(0.6 in.). To check the overlap, do this:
1. Install the headliner (A) and the pillar trims (B).
2. Apply masking tape to the headliner to mark the upper edge of each p illar trim. 3. Remove the pillar trim, and measure the headliner
overlap.
 If the overlap is less than 15 mm (0.6 in.), remove the tape, and install the pillar trim.
 If the overlap is more than 15 mm (0.6 in.), go to step 4.
4. Carefully trim the headliner with a utility knife, reducing the overlap to less than 15 mm (0.6 in.).
5. Remove the tape, and install the pillar trim.
