Start any service work only after waiting 90 seconds for both power switch OFF and negative (-) battery terminal disconnection before beginning repairs. Prior to disconnecting the negative (-) battery terminal always check DTCs since malfunction symptoms are hard to detect and SRS components must never experience hot air or fire exposure. An SRS parts check needs to happen after any collision regardless of Air Bag deployment status while Air Bag sensors require removal in cases where impact could occur during repair work. The replacement of SRS components should utilize new parts while prohibiting both maintenance work and the disassembling or repair attempts of these systems. Additionally, all damaged or dropped SRS parts must be replaced. High impedance ohmmeter/voltmeter measuring at least 10 kOhms/V must be used for all electrical troubleshooting tasks while following the warnings written on attached information labels. Perform an SRS warning light check when the work on SRS parts has been completed. Document original memory settings on each system before removing the negative (-) battery terminal and then restore the settings at the completion of work. Follow all safety measures provided by the manufacturer for mobile communication systems that are present in the vehicle.
