Restraints and Safety Systems: Service Precautions
CAUTION- When servicing a vehicle, be sure to turn the ignition switch OFF, disconnect the ground cable from the battery, and wait for more than 20 seconds before starting work.
- The airbag system is fitted with a backup power source. If the airbag system is serviced within 20 seconds after the ground cable is disconnected, it may inflate.
- If sensors, airbag module, airbag control module, pretensioner, and harness are deformed or damaged, replace them with new genuine parts.
- When checking the system, be sure to use a digital circuit tester. Use of an analog circuit tester may cause the airbag to activate erroneously.
- When checking, use a test harness. Do not directly apply the tester probe to any connector terminal of the airbag.
- Do not check continuity of the airbag modules for driver, passenger or pretensioner.
- Do not drop the airbag modulator parts, subject them to high temperature over 93 degree C (199 degree F), or let water, oil, or grease get on them; otherwise, the internal parts may be damaged and reliability greatly lowered.
- If any damage, opening, or rust is found on the airbag system wire harness, do not attempt to repair using soldering equipment. Be sure to replace the faulty harness with a new genuine part.
- Install the wire harness securely with the specified clips to avoid interference or tangled up with other parts.
- Do not allow water or oil to come in contact with the connector terminals. Do not touch the connector terminals.
- Either of the airbag parts, or pretensioner must not be disassembled.
- After removal, keep the airbag module with the pad facing upward on a dry, clean, and flat surface away from heat and light sources, and moisture and dust.
- Do not use the airbag or pretensioner parts from other vehicles. Always replace defective parts with new parts.
- Never re-use a deployed airbag or pretensioner.
- When painting or performing sheet metal work on the front part of the vehicle, including the front wheel apron, front fender, and front side frame, remove parts and take utmost care not to apply paint or the flame of the welding burner directly to the front sub sensors and wire harness of the airbag system.
- When storing a removed airbag module, do not place any objects on it or pile airbag modules on top of each other. If the airbag inflates for some reason when it is placed with its pad side facing downward or under any object, a serious accident may result.
