Following the exact service sequence remains essential to stop accidental SRS deployments causing critical accidents and maintain SRS functionality when required. Service requirements start after the ignition has been turned off followed by disconnecting the negative terminal cable at least 90 seconds later because the SRS maintains its power supply. Exposure to hot air and flames must be avoided while inspecting SRS components and all DTCs should be checked before battery disconnection due to the challenging nature of SRS malfunction symptom verification. Manual inspections of SRS components should take place following any collision activity including minor ones and sensors should get removed before operations involving the possibility of shock exposure. The replacement of SRS components should use brand new parts while prohibition exists for all dismantling and restoration work. Broken SRS materials require immediate part substitution. You should conduct electrical troubleshooting using a volt/ohmmeter that has minimum impedance of 10 kOhms/V. Always follow SRS part labels for instructions after which you should activate SRS warning light checks upon finishing your work. The process of clearing the memory requires notes about system contents before battery removal so the systems can be returned to their proper states after the repair work. Handling of Air Bag sensors requires waiting 90 seconds after disconnecting the negative (-) terminal cable before both sensor replacements and front seat side Air Bag and curtain shield Air Bag door adjustments. Install the Air Bag sensors inside the vehicle before joining and separating their wiring connections while abstaining from utilizing sensors that have fallen. Follow specific instructions for disconnection then connection of steering pad and other components including front passenger Air Bag assembly along with curtain shield Air Bag assembly, front seat outer belt assembly and driver side knee Air Bag assembly, spiral cable, center Air Bag sensor assembly and the front Air Bag sensor, side Air Bag sensor and rear Air Bag sensor until all attachments are properly locked.
