Test Q: Right Side Crash Sensor Mounting Failure (DTC B2440): Description
WARNING: This page is about a different car, the 2004 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
Restraints Control Module (RCM) monitors 2-wire current loop to right side crash sensor for signal that is out of expected range. If RCM detects an out-of-range signal, indicating a sensor mounting failure, it will store Diagnostic Trouble Code (DTC) B2440 in memory and flash Code 43 on AIR BAG warning light.
