AIR BAG SYSTEM
Deployment Procedure for Inside of Vehicle (Only When Vehicle Is To Be Scrapped)
1. Inspect the SST (Deployment tool).
2. Move the vehicle to an open space, away from strong winds, and close all the doors and windows.
3. Turn the ignition switch to LOCK position.
4. Disconnect the negative battery cable and wait for more than 1 minute.
5. Follow the appropriate procedure for deploying the driver-side air bag module, passenger-side air bag module,
side air bag module, curtain air bag module, or pre-tensioner seat belt.
Curtain air bag module (WGN)
1. Remove the headliner.
2. Disconnect the curtain air bag module connector.
3. Connect the SST (Adapter harness) to the curtain
air bag module.
4. Connect the SST (Deployment tool) to the SST
(Adapter harness).
5. Connect the red clip of the SST (Deployment tool)
to the positive battery terminal and the black clip
to the negative battery terminal.
6. Verify that the red light on the SST (Deployment
tool) is illuminated.
7. Make sure all persons are standing at least 6 m
{20 ft} from the vehicle.
8. Press the activation switch on the SST
(Deployment tool) to deploy the curtain air bag
module.
Deployment Procedure for Outside of Vehicle
1. Inspect the SST (Deployment tool).
2. Turn the ignition switch to LOCK position.
3. Disconnect the negative battery cable and wait for more than 1 minute.
4. Follow the appropriate procedure for deploying the driver-side air bag module, passenger-side air bag module,
side air bag module, curtain air bag module, or pre-tensioner seat belt.

Connect each unit connector.
Turn the ignition switch to the ON position.
Measure the voltage between DLC-2 terminals CAN_L and CAN_H.
Is the voltage 2.0—3.0 V?
Turn the ignition switch to the LOCK position.
Measure the resistance between DLC-2 terminals CAN_L and
CAN_H.
Is the resistance 59—65 ohms?
Replace any units that
do not respond.Disconnect the PCM connector.
Measure the resistance between PCM
connector terminals 2R and 2U
(except MZR-CD (RF Turbo)) or 13 and
39 (MZR-CD (RF Turbo)).
Is the resistance 118—130 ohms?
Replace the PCM.
Disconnect the instrument cluster connector.
Measure the resistance between instrument cluster connector
terminals 2W and 2X.
Is the resistance 118—130 ohms?
Replace the instrument
cluster.Turn the ignition switch to the LOCK position.
Disconnect the connector of any unit that does not respond.
