Installation

Follow all safety precautions when working on pyrotechnic components. Refer to => [ Restraint System Components, Safety Precautions and General Information ] Restraint System Components, Safety Precautions and General Information.

Install in reverse order of removal. Note the following:

Before handling airbag units (for example, when disconnecting the harness connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.

- Route and secure wiring according to photos or sketches that were made.

- Ensure all connectors are engaged correctly.

• Make sure the connectors are installed all the way in and are secure.

• Make sure the wires do not get caught.

Ignition must be on when connecting battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. Maintain personal safety when connecting the battery by staying out of airbag deployment areas, keeping a distance from belt tensioners/seat belts and ensuring no other people are in the vehicle interior at the moment when the battery is connected.

- Switch on ignition.

- Connect the battery ground cable with the ignition turned on.

- If the airbag indicator lamp (K75) indicates a fault after installation, the DTC memory must be checked, deleted and checked again. Refer to Vehicle diagnostic tester.
