B2230 - FAULT CODE - OBD2

B2230 FORD, LINCOLN, MAZDA, MERCURY: SHORT TO BATTERY IN DRIVER'S AIRBAG CIRCUIT

The Airbag is a safety system, which is passive in that it remains deactivated unless factors such as collisions or deceleration require it to be activated. This system has a control unit that has predetermined values and in this way, its normal operation is checked. If these values are exceeded or are not within the corresponding range, the unit triggers the ignition of a propellant gas that quickly inflates a fabric bag. Should the vehicle be involved in an accident, the vehicle occupants are protected by the bags, which are ejected in a controlled manner through the ventilation openings. The location of these bags varies according to the vehicle model, and they are located at the front or side of the vehicle.

The Airbag Control Module constantly monitors the Airbag controller circuit. If the Airbag Control Module detects that the driver’s airbag circuit is shorted to the battery, the B2230 OBDII diagnostic code will be set.

• Check Engine light illuminated.
• The Airbag light illuminates incorrectly or blinks.
• During collisions, the Airbag does not activate.

B2230 OBD2 fault code is set for one of the following reasons:

• Airbag Control Module circuit connections may have been damaged.
• The driver's Airbag wiring may be faulty.
• The driver's Airbag may be defective.
• Clockspring may have deficiencies.
• Airbag Control Module may have been damaged.

To troubleshoot the DTC B2230 OBDII code you must do the following:

• Consult the Technical Service Bulletins.
• Check with a scanner to see if any error codes are stored with the B2230. If these codes are related to an Airbag failure, diagnose them in the order shown.
• Inspect all wires in the driver's Airbag circuit and the Airbag Control Module wires. If any of these are found to be damaged by corrosion, burns, or wear, make the appropriate corrections.
• Perform electrical tests on the driver's Airbag circuit, in order to verify that it does not have deficiencies in the connections that produce the short-circuit. If obvious damage is found, proceed with the appropriate adjustments.
