SRS SERVICE PRECAUTIONS

WARNING:
- In order to avoid injury to yourself or others from accidental deployment of the air bag during servicing, read and carefully follow all the precautions and procedures described.

- After disconnecting the battery cable, wait 60 seconds or more before proceeding with the following work. The SRS system is designed to retain enough voltage to deploy the air bag for a short time even after the battery has been disconnected, so serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cables are disconnected.
- Battery posts, terminals and related accessories contain lead and lead compounds. WASH HANDS AFTER HANDLING.
- Do not use any electrical test equipment on or near the SRS components, except those specified.
- Never Attempt to Repair the Following Components: SRS-ECU, Clock Spring, Air Bag Module. If any of these components are diagnosed as faulty, they should only be replaced, in accordance with the INDIVIDUAL COMPONENT SERVICE procedures.

SRS-ECU Terminal Part 1:

SRS-ECU Terminal Part 2:

- Do not attempt to repair the wiring harness connectors of the SRS. If any of the connectors are diagnosed as faulty, replace the wiring harness. If the wires are diagnosed as faulty, replace or repair the wiring harness according to the table.

WARNING:
- Inspection of the SRS-ECU connector harness should be carried out by the following procedure. Insert the backprobing tool into connector from harness side, and connect the tester to backprobing tool. If any tool other than backprobing tool is used, it may cause damage to the harness and other components. Furthermore, measurement should not be carried out by touching the backprobing tool directly against the terminals from the front of the connector. The terminals are plated to increase their conductivity, so if they are touched directly by the backprobing tool, the plating may break, which will decrease reliability.
- The SRS components should not be subjected to heat over 93 °C (200 °F), so remove the SRS-ECU, air bag module, and clock spring before drying or baking the vehicle after painting.
- After servicing the SRS system, check the warning light operation to make sure that the system functions properly.
- Make certain that the ignition switch is "LOCK" (OFF) position when the scan tool is connected or disconnected.
- If you have any questions about the SRS system, please contact your local distributor.
