cautionNever heat or incinerate the airbag modules and the seat belt pre-tensioners.
1. In order to avoid injury to yourself or others from accidental deployment of the SRS air bag during servicing, read and carefully follow all the precautions and procedures described in this manual.
2. Be sure to use the tester and special tools specified in this manual (Special tool: refer to , tester: refer to ).
3. Never attempt to repair the following components:
  • SRS-ECU
  • Driver's air bag module
  • Clock spring
  • Passenger's (front) air bag module
  • Curtain air bag module
  • Knee air bag module
  • Front seat assembly incorporating side-airbag module
  • Seat belt with pre-tensioner
  • Front impact sensor
  • Side impact sensor
 
4. Never attempt to repair the wiring harness connectors of the SRS. If a defective wiring harness is found, repair or replace it by referring to the table follows.

SRS-ECU terminal No.Destination of wiring harnessMeasures
6, 7Instrument panel wiring harness → knee air bag module (squib)Repair or replace the instrument panel wiring harness.
8, 9Instrument panel wiring harness → front wiring harness → front impact sensor (LH) Repair or replace the wiring harnesses.
12, 13Instrument panel wiring harness → front wiring harness → front impact sensor (RH)
15Instrument panel wiring harness → hazard warning lamp switch (passenger’s air bag ON indicator lamp)Repair or replace the instrument panel wiring harness.
16Instrument panel wiring harness → ETACS-ECU (fuse No. 16)
18, 19Instrument panel wiring harness → passenger’s air bag cut OFF switch
21Instrument panel wiring harness → hazard warning lamp switch (passenger’s air bag OFF indicator lamp)
23Instrument panel wiring harness → earth
24, 25Instrument panel wiring harness → CAN bus line
26, 27Instrument panel wiring harness → clock spring → driver's air bag module (squib)Replace the clock spring, or repair or replace the instrument panel wiring harness.
28Instrument panel wiring harness → diagnosis connector (disposal tool)Repair or replace the instrument panel wiring harness.
29, 30Instrument panel wiring harness → passenger's (front) air bag module (squib)
46, 47Instrument panel wiring harness → floor wiring harness → seat belt pre-tensioner (driver's side) Repair or replace the wiring harnesses.
48, 49Instrument panel wiring harness → floor wiring harness → seat belt pre-tensioner (front passenger's side)
69, 70Instrument panel wiring harness → floor wiring harness → lap pre-tensioner
71, 72Instrument panel wiring harness → floor wiring harness → side-airbag module (RH)
73, 74Instrument panel wiring harness → floor wiring harness → side-airbag module (LH)
109, 110Floor wiring harness → curtain air bag module (LH)Repair or replace the floor wiring harness.
102, 103Floor wiring harness → side impact sensor (RH)
104, 105Floor wiring harness → side impact sensor (LH)
106, 107Floor wiring harness → curtain air bag module (RH)
111, 112Floor wiring harness → rear seat belt pre-tensioner (RH)
113, 114Floor wiring harness → rear seat belt pre-tensioner (LH)

 
5. Before maintenance, wait for 60 seconds or more after the disconnection of the battery (-) terminal. Wrap the disconnected (-) terminal with tape for insulation. The condenser inside SRS-ECU keeps a voltage necessary to expand the air bag for a certain period even after the ignition switch to the "LOCK" (OFF) position <Vehicles without KOS> or put the power supply mode is "OFF" <Vehicles with KOS>. Therefore, if any operation is performed before the period elapses, it may cause serious damage.
6. If the influence of heat is suspected during painting work, remove the following parts:
  • 93°C or higher SRS-ECU, air bag modules, clock spring, front impact sensors, side impact sensors
  • 90 °C or higher Seat belt with pre-tensioners
7. After the maintenance of the SRS air bag and seat belt with pre-tensioner is completed, be sure to delete the diagnosis code and check whether the SRS warning lamp lights up (refer to ).
