SUPPLEMENTARY RESTRAINT SYSTEM (SRS)

Precautions

Making the system safe

Before working on, or in the area of, the SRS, make the system safe as follows: 1. Remove the key from ignition switch. 2. Disconnect both battery leads, earth lead first. 3. Wait 10 minutes to allow the SRS back-up power to fully discharge.

General

Carefully inspect SRS parts before installation. Do not install a part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.

The airbag ECU is a shock sensitive device and must be handled with extreme care. Because the crash sensor is incorporated inside the airbag ECU, it is imperative that the bolts securing the airbag ECU and its bracket are tightened to their correct torque.

Do not install used SRS parts from another vehicle. When repairing a SRS, use only new parts.

Always use new fixings when replacing SRS parts.

Do not use a multimeter or other general test equipment to check SRS parts or connectors.

After completing work, check that the electrical connectors are installed correctly.

Handling and storage

WARNING: If the airbag is improperly stored face down, accidental deployment could propel the unit with enough force to cause serious injury.

CAUTION: Improper handling or storage can internally damage the airbag module, making it inoperative. If you suspect the airbag module has been damaged, install a new unit and refer to the Workshop Manual for Deployment/Disposal Procedures.

Do not allow anything to rest on an airbag module.

When carrying an airbag module, hold it by the cover, with the cover uppermost and the base away from your body. Do not wrap your arms around the module.

Do not try to disassemble an airbag module or seat belt pretensioner. They have no serviceable parts and, once deployed, cannot be repaired or reused.

Do not expose an airbag module or seat belt pretensioner to heat exceeding 85°C/185°F) or allow it to be contaminated with oil, grease, detergent or water.

For temporary storage of an airbag module or seat belt pretensioner during service, place in a designated storage area or, if no designated storage area is available, in the loadspace of the vehicle; always lock the vehicle and inform the workshop supervisor.

Airbag modules and seat belt pretensioners are classed as explosive articles. For overnight and longer term storage, they must be stored in an approved, secure steel cabinet which has been registered by the local authority.
