Installation

• Disconnect both battery leads, earth lead first before beginning work.
• Wait 10 minutes for the SRS DCU back-up power circuit to discharge.

The SRS system uses energy reserve capacitors to keep the system active in the event of electrical supply failure under crash conditions. It is necessary to allow the capacitor sufficient time to discharge (10 minutes) in order to avoid the risk of accidental deployment.

WARNING: Always disconnect both battery leads before beginning work on the SRS system. Disconnect the negative battery lead first. Never reverse connect the battery.

INSTALLATION

In order to assure system integrity, it is essential that the SRS system is regularly checked and maintained so that it is ready for effective operation in the event of a collision. Carefully inspect SRS components before installation. Do not install a part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.

WARNING: The integrity of the SRS system components are critical for safety reasons. Ensure the following precautions are always adhered to: • Never install used SRS components from another vehicle or attempt to repair an SRS component. • When repairing an SRS system, only use genuine new parts. • Never apply electrical power to an SRS component unless instructed to do so as part of an approved test procedure. • Special Torx bolts are necessary for installing the airbag module - do not use other bolts. Ensure bolts are tightened to the correct torque. • Always use new fixings when replacing an SRS component. • Ensure the SRS Diagnostic Control Unit (DCU) is always installed correctly. There must not be any gap between the DCU and the bracket to which it is mounted. An incorrectly mounted DCU could cause the system to malfunction.

CAUTION: Ensure SRS components are not contaminated with oil, grease, detergent or water.

CAUTION: Torque wrenches should be regularly checked for accuracy to ensure that all fixings are tightened to the correct torque.

NOTE: If the SRS component is to be replaced, the bar code of the new unit must be recorded.
