SUPPLEMENTAL RESTRAINT SYSTEMS  AIRBAG SYSTEM(for NR Series Engine)  PRECAUTION  

If a mistake is made when servicing SRS parts, they may fail to operate when required. Before performing service (including installation/removal, inspection and replacement of parts), be sure to read the following precautions.

When troubleshooting the SRS, always check for DTCs before disconnecting the cable from the negative (-) battery terminal.

After turning the ignition switch off, disconnect the cable from the negative (-) battery terminal.

NOTICE:

After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.

Information labels are attached to the SRS parts. Follow the instructions on the labels.

Never disassemble or attempt to repair any of the SRS parts.

If any of the SRS parts are dropped, or if any cracks, dents or other defects are found, replace them with new parts.

Never use SRS parts from another vehicle. When replacing parts, use new parts.

Do not expose any of the SRS parts directly to high temperatures or flames.

If the vehicle has been involved in a minor collision where the SRS did not deploy, the SRS parts should be inspected before further use of the vehicle.

Do not apply grease, detergent, oil or water to the SRS parts. If applied, immediately wipe it off with a dry cloth.

When deploying or storing the SRS parts, avoid places with a high temperature (ambient temperature of 93°C (199°F) or higher for an airbag and 80°C (176°F) or higher for a pretensioner) and high humidity, and keep them away from electrical noise.

Use a voltmeter/ohmmeter with high impedance (minimum = 10 kΩ) for troubleshooting electrical circuits.

Be sure to check the SRS warning light and multi-information display after checking, removing and installing, or replacing the airbag and sensor.

When storing an airbag, do not place anything on top of it or place it in a pile.

When storing a pretensioner, do not place objects on top of it or place it in a pile.

Do not remove/install the spiral cable with sensor sub-assembly with the battery connected and the ignition switch ON.

Do not rotate the spiral cable with sensor sub-assembly without the steering wheel assembly installed, with the battery connected and the ignition switch ON.

Ensure that the steering wheel assembly is installed and aligned straight when inspecting the steering sensor.

When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock to release the interlock mechanism.

Removing the steering sensor from the spiral cable sub-assembly without using a lock pin may result in a misaligned center position of the steering sensor. Therefore, make sure to use the lock pin provided with a new spiral cable sub-assembly when removing the steering sensor from the spiral cable sub-assembly.

Be sure that the spiral cable with sensor sub-assembly is in the neutral position during installation and when removing and installing the steering wheel assembly.

NOTICE:

If the steering wheel assembly is turned without the spiral cable with sensor sub-assembly installed in the neutral position, the cable may break.

When the SRS parts are deployed (including when only an airbag or pretensioner is deployed) due to a collision, be sure to replace all sensors in the damaged areas (anywhere in need of repair) and the airbag sensor with ECU assembly.

Visually check the airbag sensors in undamaged areas for defects.

When disconnecting or reconnecting a connector of the airbag sensor with ECU assembly, front airbag sensor, side airbag pressure sensor and side No. 2 airbag sensor connectors, make sure to do so with the sensor installed to the vehicle.

If a sensor has been dropped make sure to replace it with a new one.

If a sensor has been subjected to strong impact make sure to replace it with a new one.

Never disassemble any of the SRS parts.

When the airbag sensor with ECU assembly is replaced, perform initialization.

All wire harnesses except unexposed harnesses in the engine compartment are colored yellow.

As special connectors are used, be careful when handling them.

Before using an electric welder on the vehicle, remove any SRS parts around the area being repaired.

Before repairs, remove the airbag sensor assemblies/airbag sensor with ECU assembly if impacts are likely to be applied to the sensor during repairs.

Never expose an airbag sensor directly to high temperatures.

As the SRS parts are very hot after being deployed, ensure that all wire harnesses and connectors around deployed SRS parts are not damaged.

Do not make any modifications to the front door that may change the inner pressure of the front door.

Do not allow any foreign matter to enter the side airbag pressure sensor as it may affect the pressure detection performance of the sensor.

When painting the front door, remove or apply protective tape to the side airbag pressure sensor to prevent paint from attaching to it.

Make sure that the parts which maintain the sealing performance of the front door are securely installed. If the sealing performance of the front door decreases, the pressure detection performance of the side airbag pressure sensor may be affected. Repair or replace parts as necessary.

When the vehicle is damaged in a collision, even if the SRS parts are not deployed.

When SRS system DTCs are output.
