Attention! The Camry is equipped with a passive safety system that includes a driver airbag, a front passenger airbag, a side airbag and a side curtain airbag. Violation of the sequence of maintenance work can lead to unexpected operation of the passive safety system during maintenance with the possibility of an accident. Further, if a mistake was made during the maintenance of the passive safety system, then it is possible that the passive safety system will not perform its functions in a collision. Before performing maintenance (including removal or installation of elements, their inspection or replacement), read the following points carefully, and then carry out the operations described in the repair manual.
You can start working 90 seconds after the ignition key is turned to the «LOCK», and the wire is disconnected from the negative (–) battery outlet.
(The passive safety system is equipped with a spare power source, therefore, if you start work earlier than 90 s from the moment the wire is disconnected from the negative (–) battery terminal, the passive safety system may be triggered). Do not expose airbag modules in the horn button, instrument panels, etc., or airbag sensors, to direct exposure to hot air or flames.
Attention! Signs of a malfunction in a passive restraint system are difficult to confirm, thus diagnostic codes are the most important source of information when troubleshooting. When troubleshooting the SRS, always check the diagnostic codes before disconnecting the battery.
Even in cases of minor collisions, when the passive restraint system does not work, the modules and sensors of the airbags must be tested.
Before repairing, remove the airbag sensor if there is a possibility that the sensor may be impacted during the repair.
Never use parts of the passive safety system from another car. When replacing parts, replace them with new ones.
Never disassemble or repair airbag modules and sensors for reuse.
If airbag modules and sensors have been dropped or have cracks, dents, or other defects in their housings, brackets, or connectors, replace them with new ones.
Use a high impedance volt/ohmmeter when troubleshooting system electrical circuits (not less than 10 kOhm/V).
Elements of the passive safety system are provided with information labels. Follow the directions on these labels.
After work on the SRS is complete, check the SRS warning lamp. When the wire is disconnected from the negative (–) battery output, the memory of the clock and the audio system is de-energized. Before starting work, write down the contents of the audio system's memory. At the end of the work, restore the audio system settings and set the time on the clock. To prevent memory erasure in storage systems, never use an external backup power source.
All connectors of the passive safety system have a distinctive yellow color. The SRS connectors shown on the previous page have a special design and function to ensure high reliability. The pins of these connectors are gold plated for high reliability and durability.
