SUPPLEMENTAL RESTRAINT SYSTEM – TROUBLESHOOTING
From the results of the above inspection, the malfunctioning part can now be considered normal.
To make sure of this, use the simulation method to check. If the malfunctioning part cannot be
detected by the simulation method, replace all SRS components including the wire harness.
