The SRS is a safety device which, when used with the seat belt, is designed to help protect the driver and front passenger in a frontal impact exceeding a certain set speed limit. The system consists of the SRS unit, including safing sensor and impact sensor, the cable reel, the driver's airbag, the front passenger's airbag, side airbags, side curtain airbags, seat belt tensioners, front impact sensors, side impact sensors and roll rate sensor. Since the driver's and front passenger's airbags use the same sensors, both normally inflate at the same time. However, it is possible for only one airbag to inflate. This can occur when the severity of a collision is at the margin, or threshold, that determines whether or not the airbags will deploy. In such cases, the seat belt will provide sufficient protection, and the supplemental protection offered by the airbag would be minimal.
- Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs.
- Carefully inspect any SRS part before you install it.
- Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
- Before removing any SRS parts (including disconnection of connectors), always disconnect the SRS connector.
- Use only a digital multimeter to check the system. Ensure that the multimeter output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury.
- Do not put objects on the front passenger's airbag.
- The original radio has a coded theft protection circuit. Be sure to get the customer's radio and navigation system codes and write down the frequencies for the radio's preset stations before disconnecting the battery negative cable.
- Before returning the vehicle to the customer, enter the radio and navigation system codes, then enter the customer's audio presets and set the clock.
- After disconnecting the battery negative cable, perform the powertrain control module (PCM) idle learn procedure and the power window control unit reset procedure.
- Never perform electrical inspections to the airbags, such as measuring resistance.
- Do not position yourself in front of the airbag during removal, inspection, or replacement.
