B1892 MAZDA Description

The air bag indicator is designed to illuminate for 6 (??) seconds when the ignition switch is turned to the RUN position. This initial 6 seconds of illumination is considered the normal operation and is called Prove-Out of the air bag indicator. The air bag indicator is then used to warn the driver that there is a fault in the air bag Supplemental Restraint System (SRS). The air bag Restraint Control Module (RCM) monitors the air bag indicator for open and short to ground conditions. If the ECS detects an open or short to ground condition on the air bag indicator circuit, it will store a Diagnostic Trouble Code (DTC) B1892 in memory. If the RCM detects a circuit failure on the connection to the cluster, it will store diagnostic trouble code (DTC) B1891 in memory and flash lamp on the air bag indicator.
