the purpose of reuse, never disassemble and repair the following parts. * Never use SRS parts from another vehicle. When replacing parts, replace with new parts. * Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected; * Do not expose the following parts directly to hot air or flame; * Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair. * Steering wheel pad * Side airbag assembly * Front passenger airbag assembly * Curtain shield airbag assembly * Seat belt pretensioner * Center airbag sensor assembly * Front airbag sensor assembly * Work must be started more than 90 seconds after the engine switch is pushed to the "OFF" position and the negative (-) terminal cable is disconnected from the battery. (The SRS is equipped with a back-up power source so that if work is started within 90 seconds from disconnecting the negative (-) terminal cable of the battery, the SRS may deploy.) * Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. * Rear airbag sensor assembly NOTICE :When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions and the procedure, and precautions in the Repair Manual applicable for the model year. * Side airbag sensor assembly * When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will be cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function. However, it is not possible to make a record of these memory contents. So when the work is finished, it will be necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each system, never use a back-up power supply from outside the vehicle. * Knee airbag assembly J21 24 GSW3 A GR LA 10 LA 9 24 GSW W DCM (Telematics Transceiver) J114 (*3) (*3) (*3) (*3) (*3) (*3) * 3 :w/ Occupant Classification System (*9) (*9) (*9) (*9) BR (*10) * 9 :w/ Tire Pressure Warning System *10 :w/o Tire Pressure Warning System * 9 :w/ Tire Pressure Warning System *10 :w/o Tire Pressure Warning System BR(*10) BR(*10) BR(*9) BR(*9) BR(*9) BR(*10) BR(*10) BR(*9) BR(*9) BR(*10) BR(*10) BR(*9) (*9) BR (*10) Junction Connector A29(A),J10(B) Junction Connector J27 Certification ECU Assembly 2 L GR 19 LA A 20 B 12 27 P33 MPX1 28 MPX2 Junction Connector P24(A),P25(B) A30(A),Q3(C) Main Body ECU LH (Cowl Side J/B LH) MPX2 MPX1 C 15 A 17 1 Front Controller 2 2F 6 2F 5 7 MPX1 GR GR 5 Power Source Control ECU 24 MPX2 J55 GR GR GR GR LL 8 GR 9 MPX1 3 MPX2 Power Window Regulator Master Switch Assembly M18 2 5 RK 2 (BAT) 1 10A MPX-B BECU 26 G-R W W B B L L J47(A),P14(B),Q32(C) Center Airbag Sensor Assembly * 8 :w/o LEXUS Navigation System * 7 :w/ LEXUS Navigation System * 8 :w/o LEXUS Navigation System * 7 :w/ LEXUS Navigation System * 8 :w/o LEXUS Navigation System * 7 :w/ LEXUS Navigation System GR G-R *11 :Korea (*11) (*11) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) (*3) * If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. * After work on the SRS is completed, check the SRS warning light. * Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice. * Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system. 2 1 C C 2 1 z6(C) Driver Side Squib 2nd Step Circuit Spiral Cable Sub-Assembly J25(A),z5(B),z6(C) A L-W L 19 B 12 10A DOME 1 (BAT) 2 B A 23 10A ECU-IG RH (IG) IG 15 ACC 22 (ACC) 7.5A ACC Main Body ECU RH (Cowl Side J/B RH) J75(B) W-B 7 RD 5 RA W-B 4 GND2 20A FR DOOR RH (BAT) 20A TI&TE ALTB 6 (BAT) 2 BATB W-B 17 RD 5 GND1 GR 21 RJ 14 MPX1 Main Body ECU RH (Cowl Side J/B RH) J75(B) BR BR GR GR BR BR P(*7) P(*8) P(*8) P(*7) GR (*8) V (*8) GR (*7) V (*7) 6 PAON 7 P-AB 4 PAON 13 P-AB PAON P-AB 23 A 17 A LA 21 LA 8 LD 17 LA 3 SB G ECM A6 V(*7) GR(*7) V(*8) GR(*8) V(*7) GR(*7) V(*8) GR(*8) JA5 JA5 JP2 PT2 PT2 PT2 PT2 PT2 PT2 PT2 JA1 JA1 Ja1 Ja1 Ja1 Ja1 Qd1 Qd1 Pc1 Pc1 PQ2 MQ1 MQ2 JA3 JA4 JA4 JA3 JA3 PT2 J4 J2 J1 J2 J4 J4 J2 P1 J1

Электрические цепи подушек безопасности защищены предохранителем IG2 на 10 Ампер (красный). На этом автомобиле система SRS AirBag имеет коммуникацию по CAN-BUS.
