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. * Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair. 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. 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. * * * (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.) To avoid erasing the memory in each system, never use a back-up power supply from outside the vehicle. * Do not expose the following parts directly to hot air or flame; 2 BDR- Front Side Airbag Sensor RH R7 Front Side Airbag Sensor LH S5 Y BDR+ BDL- Y-B BDL+ BDR- Y-B BDR+ BDL- BDL+ N16 N19 Y Y Y-B Y Y-B 1 2 1 2 2 1 2 1 22 20 Junction Connector L171 * 6 :w/ Rear Side Airbag (*6) (*6) (*6) (*6) (*6) (*6) (*6) (*6) Door Side Airbag Sensor RH Door Side Airbag Sensor LH Front Pretensioner LH Multi-Media Module Receiver Assembly 33 34 (*7) (*7) R (*8) SB (*8) R (*8) B (*8) I 33 (*8) I 34 (*7) * 7 :Except Korea * 8 :Korea * * * If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector, replace with new one. For the purpose of reuse, never disassemble and repair the following parts. Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected; * Never use SRS parts from another vehicle. When replacing parts, replace with new parts. 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. * Active headrest airbag assembly * Door side airbag sensor assembly 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. * Rear seat airbag assmbly * * * Work must be started more than 90 seconds after the power switch is pushed to the "OFF" position and the negative (-) terminal cable is disconnected from the battery. 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. * 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 * Rear airbag sensor assembly LA4 LA4 Ls1 Ls1 NR3 NR3 NS3 LA2 LA2 LK1 LK1 LK1 LK1 Sf2 Sf2 Rf2 Rf2 Rf3 Rf3 Re3 Re3 Re3 Re1 Re3 LR1 LA1 LA1 LR1 Se3 Se3 Re4 Re4 LA1 NS3 S2 L4 L3 R3 L1 L1
