CAUTION:
The LAND CRUISER is equipped with SRS, which comprises a driver airbag, front passenger airbag, side airbag and curtain shield airbag. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate when required. Before performing servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct procedures described in the repair manual.
Work must be started 90 seconds after the ignition switch is turned to the ”LOCK” 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 be deployed.)
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor assembly directly to hot air or flames. NOTICE:
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.
Even in the case of a minor collision where the SRS does not deploy, the steering wheel pad,front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly and seat position sensor assembly should be inspected (See page RS–18, RS–32, RS–47, RS–60, RS–71, RS–76, RS–81, RS–87 and RS–92).
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor,side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor assembly in order to reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector,replace it with new one.
Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system’selectrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instructions on the notice.
After work on the SRS is completed, perform the SRS warning light check (See page DI–692). www.m448中国最大的资料库下载
