Installation

INSTALLATION

PROCEDURE

1. INSTALL SIDE AIRBAG PRESSURE SENSOR

(a) Check that the engine switch (for Gasoline Model) or power switch (for HV Model) is off.

(b) Check that the cable is disconnected from the negative (-) auxiliary battery terminal.

CAUTION:

Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

(c) Before connecting the connector, check that the position of the white housing lock is as shown in the illustration.

(d) Engage the 2 stoppers to temporarily install the side airbag pressure sensor to the front door panel.

*a Stopper

(e) Install the side airbag pressure sensor with the nut.

Torque:

9.0 N·m {92 kgf·cm, 80 in·lbf}

NOTICE:

• If the side airbag pressure sensor has been dropped, or there are any cracks, dents or other defects in the case or connector, replace it with a new one.
• When installing the side airbag pressure sensor, make sure that the wire harness does not interfere with other parts and is not pinched.
• Make sure that the side airbag pressure sensor stopper is securely engaged to the front door panel.
• Keep the stud bolt and waterproof rubber seal free of foreign matter.

(f) Connect the connector to the side airbag pressure sensor.

NOTICE:

When connecting any airbag connector, take care not to damage the airbag wire harness.

HINT:

• Be sure to connect the connector until it is locked (when locking, make sure that a click sound can be heard).
• When the connector is locked, the white housing lock will slide. Do not hold the white housing lock or the part (A) as it may result in an insecure connection.

(g) Check that there is no looseness in the installed parts of the side airbag pressure sensor.

On-vehicle Inspection

ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

CAUTION:

Be sure to correctly follow the removal and installation procedures for the side airbag pressure sensors.

PROCEDURE

1. INSPECT SIDE AIRBAG PRESSURE SENSOR (for Vehicle not Involved in Collision)

(a) Perform a diagnostic system check.

for Gasoline Model: Click here

for HV Model: Click here

2. INSPECT SIDE AIRBAG PRESSURE SENSOR (for Vehicle Involved in Collision and Airbag not Deployed)

(a) Perform a diagnostic system check.

for Gasoline Model: Click here

for HV Model: Click here

(b) Visually check the side airbag pressure sensors for defects if a front door of the vehicle or the area around a front door is damaged.

HINT:

The defects are as follows:

• Cracks in the sensor housing
• Dents in the sensor housing
• Chips in the sensor housing
• Cracks or other damage to the connector
• Damage to the waterproof rubber seal

OK:

No defects are found.

If any defects are found, replace the side airbag pressure sensor with a new one.

3. INSPECT SIDE AIRBAG PRESSURE SENSOR (for Vehicle Involved in Collision and Airbag is Deployed)

(a) When airbags have deployed as the result of a collision, be sure to replace all side airbag pressure sensors in the damaged areas (anywhere in need of repair).

(b) Visually check the side airbag pressure sensors in undamaged areas for defects.

HINT:

The defects are as follows:

• Cracks in the sensor housing
• Dents in the sensor housing
• Chips in the sensor housing
• Cracks or other damage to the connector
• Damage to the waterproof rubber seal

OK:

No defects are found.

If any defects are found or a side airbag pressure sensor has detected a major collision, replace the side airbag pressure sensor with a new one.
