Impact Sensor: 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 and harness are deformed or damaged, replace them with new genuine parts.
Do not use the airbag parts from other vehicles.
Always replace defective parts with new parts.
Never re-use a deployed airbag.
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.
