Airbag System Diagnostics

CAUTION
- When servicing a vehicle, be sure to turn the ignition 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. After disconnecting the battery ground cable, the airbag may deploy if you do not wait for more than 20 seconds before starting airbag system servicing.
- If the airbag warning light illuminates, repair the vehicle immediately. Otherwise, the airbag or pretensioner may activate incorrectly, or not inflate in an actual collision.
- If sensors, airbag module, airbag control module, pretensioner or harness is deformed or damaged, replace with new parts.




- Do not use the airbag system and pretensioners on other vehicles. When replacing parts, be sure to replace them with new parts.




- Do not check continuity of the airbag modules on the driver's side, passenger's side, side airbag modules, or the pretensioner.




- When checking the airbag system, be sure to use a digital circuit tester. Use of an analog circuit tester may cause the airbag to activate erroneously due to a minimal current inside tester.




- When checking, use a test harness. Do not touch the tester probe directly to the airbag connector terminal.




- Do not drop the airbag system parts, or keep them at high temperature over 93 degrees C (199 degrees F), or let water, oil or grease get on them; the internal parts may be damaged and reliability greatly lowered.




- If damage, open circuit or rust is found on airbag system wiring harness, do not use solder to repair Replace the faulty harness with a new genuine part.




- Install the wiring harness securely with specified clips to avoid interference or becoming tangled with other parts.




- Do not allow water or oil to come in contact with the connector terminals. Also, do not touch the connector terminals.




- Do not disassemble the airbag modules on the drivers side, passengers side, or for the side airbag system.
- The airbag module cannot be used again if deployed once.




- After removal, keep the airbag module with the pad side facing upward on a dry, clean and flat surface away from heat, light sources, moisture and dust.




- The removed front seat with airbag module must be kept at least 200 mm (8 in) away from walls and other objects.
- 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 wiring harness of airbag system.




- When painting or performing sheet metal work on the side of the vehicle, including the side sill, center pillar and front and rear doors, remove the side airbag sensors and wiring harness of the airbag system.
- Do not discard undeployed airbag module. They could easily cause a serious accident if accidentally deployed.




- When storing a removed airbag module, do not place any objects on the module or stack them 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.
