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.

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 (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.
