Live and Undeployed Pedestrian Impact Detection System Actuator
Take special care when handling or storing an undeployed Pedestrian Detection Impact System (PIDS) Actuator. A PIDS Actuator deployment produces a rapid generation of gas. This may cause the PIDS Actuator, or an object in front of the PIDS Actuator, to project through the air in the event of an unlikely deployment.
Scrapping Procedure
During the course of a vehicles useful life, certain situations may arise which will require the disposal of a live and undeployed PIDS Actuator. Do NOT dispose a live and undeployed PIDS Actuator through normal disposal channels until the PIDS Actuator has been deployed.
Do not deploy the PIDS Actuator in the following situations:
1. After replacement of a PIDS Actuator under warranty the PIDS Actuator may need to be returned undeployed to the manufacturer.
2. If the vehicle is the subject of a Product Liability report, GM-1241, or Special Field Investigation (SFI), related to the PIDS system and is subject to a preliminary investigation do NOT alter the PIDS Actuator system in any manner.
3. If the vehicle is involved in a campaign affecting the PIDS Actuator follow the instructions in the Campaign Service Bulletin for proper PIDS Actuator handling procedures.
Deployment Procedures
Deploy the PIDS Actuators outside of the vehicle.
Deployment Outside Vehicle
Deploy the PIDS Actuator outside of the vehicle when the vehicle will be returned to service. Situations that require deployment outside of the vehicle include the following:
* Using the PIDS diagnostics, you determine that the PIDS Actuator is malfunctioning.
* The PIDS Actuator is cosmetically damaged, scratched, or broken.
* The PIDS Actuator pigtail is damaged.
* The PIDS Actuator connector is damaged.
* The PIDS Actuator connector terminals are damaged.
Deployment and disposal of a malfunctioning PIDS Actuator is subject to any required retention period.
Warning
In order to prevent accidental deployment and the risk of personal injury, do not dispose of an undeployed Pedestrian Impact Detection System (PIDS) Actuator as normal shop waste. Undeployed PIDS Actuators contain substances that could cause severe illness or personal injury if their sealed containers are damaged during disposal. Use the following deployment procedures to safely dispose of an undeployed PIDS Actuators. Failure to observe the following disposal methods may be a violation of Federal law.
1. Turn OFF the ignition.
2. Remove the ignition key.
3. Put on safety glasses.
4. Remove the PIDS Actuator.
5. Place the PIDS Actuator on a work bench, with connector side facing up and away from the surface.
6. Clear a space on the ground about 1.85 m (6 ft) in diameter for deployment of the PIDS Actuator. If possible, use a paved, outdoor location free of activity. Otherwise, use a space free of activity on the shop floor. Ensure you have sufficient ventilation.
7. Clear the area of loose or flammable objects.
8. Place PIDS Actuator in the center.
9. Inspect the SIR deployment harness and the PIDS Actuator adapter for damage. Replace as needed.
10. Short the 2 SIR deployment harness leads together using one banana plug seated into the other.
11. Connect the appropriate pigtail adapter to the SIR deployment harness.
12. Extend the SIR deployment harness and adapter to the full length of 5 m from the deployment area.
13. Connect the PIDS actuator to the adapter on the SIR deployment harness.
14. Place a 12 volt minimum/4 amp minimum power source, such as a vehicle battery, near the shorted end of the harness.
Note:
The rapid expansion of gas involved with deploying a PIDS Actuator is very loud. Notify all the people in the immediate area that you intend to deploy the PIDS Actuator.
15. Clear the area of people.
16. Separate the 2 banana plugs on the PIDS deployment harness that were shorted together earlier in the procedure.
17. Connect the SIR deployment harness wires to the power source. Deployment of the PIDS Actuator will occur when contact is made.
18. Disconnect the SIR deployment harness from the power source after the PIDS Actuator deploys.
19. If the PIDS Actuator did not deploy, disconnect the adapter and discontinue the procedure and contact the Technical Assistance Group. If deployment was successful, proceed to the following steps.
20. Seat one banana plug into the other in order to short the deployment harness leads.
21. Put on a pair of shop gloves.
22. Disconnect the pigtail adapter from the PIDS actuator as soon as possible.
23. . Inspect the pigtail adapter and the SIR deployment harness. Replace as needed.
24. Dispose of the deployed PIDS Actuator through normal refuse channels.
25. Wash your hands with a mild soap.
