AB-3 AIRBAG SYSTEM General Description B: CAUTION • When servicing a vehicle, be sure to turn the ig- nition switch to OFF, disconnect the ground cable from 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 the airbag warning light illuminates, repair the vehicle immediately. Airbag or pretensioner may inflate incorrectly, or not inflate in collision. • If sensors, airbag module, airbag control module, pretensioner, and harness are deformed or damaged, replace them with new genuine parts. • When checking the airbag system, be sure to use a digital circuit tester. Infinitesimal electric current in an analog circuit tester may cause the airbag to activate erroneously. • When checking, use a test harness (1). Do not directly apply the tester probe to any connector ter- minal of the airbag. Damage to the connector termi- nal may cause the airbag to activate erroneously. • Do not check continuity of either of the airbag modules for driver, passenger or side, or pretensioner.

AB-4 AIRBAG SYSTEM General Description • Do not drop the airbag modulator parts, subject them to high temperature over 93°C (199°F), or let water, oil, or grease get on them; otherwise, the in- ternal 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 speci- fied 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 modules for driver, passenger or side, or pretensioner must not be disassem- bled. • The removed front seat with the airbag module must be kept at least 200 mm (8 in) away from walls and other objects. • Do not use the airbag or pretensioner parts from other vehicles. Always replace defective parts with new parts. • Never reuse 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 the front sub sensors and wire harness of the airbag system.
