A self-diagnostic circuit is built into the SRS unit; when the ignition switch is turned to ON (II), the SRS indicator comes
on and goes off after about 6 seconds if the system is operating normally.
If the indicator does not come on, or does not go off after 6 seconds, or comes on while driving, it indicates an
abnormality in the system. The system must be inspected and repaired as soon as possible.
For better serviceability, the SRS unit memory stores a DTCs related to the cause of the malfunction, and the unit is
connected to the data link connector (DLC). This information can be read with the HDS when it is connected to the DLC
(see page 24-22).
NOTE: Before you disconnect the negative cable from battery for troubleshooting, review Battery Terminal
Disconnection and Reconnection (see page 22-68).

NOTE: Review the seat replacement procedure
(see page 20-118) before doing repairs or service. 1. Do the battery terminal disconnection procedure (see page 22-68), then wait at least 3 minutes
before starting work.
2. Remove the front seat assembly (see page 20-118).
3. Remove the front door sill inner trim (see page 20-66).
4. Remove the lower B-pillar lower trim panel (see page 20-69).
5. Disconnect the floor wire harness 4P connector (A) from the side impact sensor (first) (B).
6. Using a TORX T30 bit, remove the TORX bolt (C), then remove the side impact sensor (first). 1. Install the side impact sensor (first) (A) with a new
TORX bolt (B), then connect the floor wire harness
4P connector (C) to the side impact sensor (first).
2. Do the battery terminal reconnection procedure (see page 22-68).
3. Reinstall all removed parts.
4. Clear any DTCs (see page 24-23).
5. Confirm proper operation: Turn the ignition switch to ON (II); the SRS indicator should come on for

NOTE: Review the seat replacement procedure
(see page 20-118) before doing repairs or service.
1. Do the battery terminal disconnection procedure (see page 22-68), then wait at least 3 minutes
before starting work.
2. Remove the passenger’s seat assembly (see page 20-118) and seat-back cover (see page 20-127).
3. Disconnect the ODS unit 18P connector (A) and OPDS sensor connectors (B) from the ODS unit (C).
4. Remove the two nuts (D) and the ODS unit. 1. Place the ODS unit (A) on the seat-back frame.
Tighten the two nuts (B), and connect the ODS unit
harness 18P connector (C) and OPDS sensor
connectors (D) to the ODS unit.
2. Install the seat-back cover in the reverse order of removal.
3. Do the battery terminal reconnection procedure (see page 22-68).
4. Set the seat-back in the normal position, and make sure there is nothing on the front passenger’s seat.
5. Initialize the ODS unit (see page 24-26).
6. Clear any DTCs (see page 24-23).
7. Confirm proper system operation: Turn the ignition switch to ON (II); the SRS indicator should come on
for about 6 seconds and then go off.
