Possible Causes

WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Open or short circuit in wiring harness between left side air bag and SAS control module, left side air bag malfunction or SAS control module malfunction.

  1. Inspect left side air bag

    Using scan tool, inspect resistance for PID/DATA monitor DS-AB. See PID/DATA MONITOR & RECORD  under DIAGNOSTICS. If resistance is 1.4-3.2 ohms and performing present malfunction diagnosis, replace SAS control module. See SAS CONTROL MODULE  under REMOVAL & INSTALLATION. If resistance is 1.4-3.2 ohms and performing past malfunction diagnosis, test is complete. If resistance is not 1.4-3.2 ohms, go to next step.

  2. Inspect left side air bag connector

    Turn ignition switch to LOCK position. Disable air bag system. See DISABLING SYSTEM  under DISABLING & ACTIVATING AIR BAG SYSTEM. Remove left side air bag module. See SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Inspect left side air bag module connector. If left side air bag module connector is cracked or chipped, replace wiring harness. If left side air bag module connector is not cracked or chipped, go to next step.

  3. Isolate malfunction

    Connect leads of 2 ohm resistor across terminals of left side air bag module 2-pin connector. Connect negative battery cable. Turn ignition switch to ON position. Using scan tool, inspect PID/DATA monitor OD-DSAB-ST. If PID readings are normal, replace left side air bag module. If PID readings are not normal, replace wiring harness and go to next step.

  4. Inspect SAS control module

    Turn ignition switch to LOCK position. Disable air bag system. Connect left side air bag module connector. Connect negative battery cable. Retrieve Diagnostic Trouble Codes (DTCs). See RETRIEVING DIAGNOSTIC TROUBLE CODES (DTCS)  under DIAGNOSTICS. If DTCs B1992, B1993, B1994 or B1995 are retrieved and performing present malfunction diagnosis, replace SAS control module. If DTCs B1992, B1993, B1994 or B1995 are retrieved and performing past present malfunction diagnosis, test is complete. If DTCs B1992, B1993, B1994 or B1995 are not retrieved, test is complete.
