   FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER

   The HIACE is equipped with a Supplemental Restraint System (SRS).

   CAUTION:

   Failure to carry out the service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing and lead to serious injury. Furthermore, if a mistake is made when servicing SRS, it is possible that the SRS may fail to operate properly. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following section carefully.

   
   

   1. GENERAL NOTICE

      
      

      1. As malfunctions of the SRS are difficult to confirm, the Diagnostic Trouble Codes (DTCs) become the most important source of information when troubleshooting. When troubleshooting the SRS, always check the DTCs before disconnecting the battery.

      2. Work must be started at least 90 seconds after the ignition switch is turned off and after the cable is disconnected from the negative (-) battery terminal.

         The SRS is equipped with a back-up power source. If work is started within 90 seconds after turning the ignition switch off and disconnecting the cable from the negative (-) battery terminal, the SRS may deploy.

         When the cable is disconnected from the negative (-) battery terminal, clock and audio system memory is erased. Before starting work, make a note of the settings of each memory system. When work is finished, reset the clock and audio system as before.

         CAUTION:

         Never use a back-up power source (battery or other) to avoid erasing system memory. The back-up power source may inadvertently power the SRS and cause it to deploy.

      3. In minor collisions where the SRS does not deploy, the steering pad, front passenger airbag assembly and front seat outer belt assembly should be inspected before further use of the vehicle.

   5. FRONT SEAT OUTER BELT ASSEMBLY (SEAT BELT PRETENSIONER)

      
      

      1. Never measure the resistance of the seat outer belt. This may cause the pretensioner of the seat belt to activate, which could cause serious injury.

         

      2. Never disassemble the seat outer belt.

      3. Never install the seat outer belt on another vehicle.

      4. Store the seat outer belt in an area where the ambient temperature is below 80°C (176°F), the humidity is not high and there is no electrical noise.

      5. When using electric welding anywhere on the vehicle, disconnect the airbag ECU connectors (2 pins). These connectors contain shorting springs. This feature reduces the possibility of the airbag deploying due to current entering the squib wiring.

      6. When disposing of a vehicle or the seat outer belt unit by itself, the seat outer belt should be activated before disposal Click here. Activate in a safe place away from electrical noise.

      7. As the seat outer belt is hot after being activated, allow some time for it to cool down sufficiently before disposal. Never apply water to cool down the seat outer belt.

      8. Grease, detergents, oil or water should not be applied to the front seat outer belt.

   6. AIRBAG SENSOR ASSEMBLY

      
      

      1. Never reuse an airbag sensor assembly that has been involved in a collision where the SRS has deployed.

      2. The connectors to the airbag sensor assembly should be connected or disconnected with the sensor placed on the floor. If the connectors are connected or disconnected while the airbag sensor assembly is not placed on the floor, the SRS may activate.

      3. Work must be started at least 90 seconds after the ignition switch is turned off and the cable is disconnected from the negative (-) battery terminal, even if only loosening the set bolts of the airbag sensor assembly.

   7. WIRE HARNESS AND CONNECTOR

      
      

      1. The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in the system are a standard yellow color. If the SRS wire harness becomes disconnected or the connector becomes broken, repair or replace it.

   ELECTRONIC CONTROL

   

   
   

   1. REMOVAL AND INSTALLATION OF BATTERY TERMINAL

      Note

      Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.

      
      

      1. Before performing electronic work, disconnect the cable from the negative (-) battery terminal to prevent component and wire damage caused by accidental short circuits.

      2. When disconnecting the cable, turn the ignition switch and headlight dimmer switch off and loosen the cable nut completely. Perform these operations without twisting or prying the cable. Then disconnect the cable.

      3. Clock settings, radio settings, audio system memory, DTCs and other data are erased when the cable is disconnected from the negative (-) battery terminal. Write down any necessary data before disconnecting the cable.

   2. 

      HANDLING OF ELECTRONIC PARTS

      
      

      1. Do not open the cover or case of the ECU unless absolutely necessary. If the IC terminals are touched, the IC may be rendered inoperative by static electricity.

      2. Do not pull the wires when disconnecting electronic connectors. Pull the connector itself.

      3. Do not drop electronic components, such as sensors or relays. If they are dropped on a hard surface, they should be replaced.

      4. When cleaning the engine with steam, protect the electronic components, air filter and emission-related components from water.
