Operation :

A passenger airbag(PAB) module, located in the passenger side crash pad, contains a folded cushion together with an inflator unit (as pictured above). The main circuit in the SRS control module senses and judges the force of impact and if necessary inflation of the cusion occurs. If battery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power circuit respectively will keep voltage at a constant level.

Self-diagnosis System :

A self-diagnosis circuit is built into the SRS control module, When the ignition switch is turned ON, the SRSCM indicator light turns on and turns off, after about six seconds, if the system is operating normally. If the light does not come If the light does not turn on or does not turn back off after six second, or if it lights while driving, an abnormality in the system is indicated. The system must be inspected and repaired as soon as possible. For bettery serviceability, the cause of the malfunction is stored in memory. The data link circuit passes malfunction information from memory to the data link connector (DLC). This information can then be read with the scantool connected to the DLC (16P).

When open or increased resistance in the passenger’s airbag squib occurs.When the SRS warning light remains lit and a DTC code occurs, this means an open circuit or increased resistance between control module and airbag harness has occurred.
