Air Bag Fault Codes
This page is about air bag problems that turn on the dash warning lamp.
Check Air Bag Light Code:
There are several ways to conduct an airbag check. Making sure your airbag is working properly can help reassure that you and your passengers are safe. So, check to see if your airbag system is operating correctly.
Most cars today can do an airbag diagnostic test. The test checks to see if all the sensors and circuits of the airbag are functioning. If the system detects any problems, it gives you a signal through the airbag indicator by flashing the light several times, giving you the specific problem the test has detected. These flashes are codes, each having its own meaning.
Specific Airbag Fault Codes:
Codes 01,02,03,04,05,06,07,08,09,10,11,12,13 and 14These codes are started by a single flash of the indicator light, followed by a two-second pause. After the pause, the light will flash the number of times that corresponds to the second digit of the code. Code 12 (single flash, pause, two flashes) means that there is a lost battery feed. Code 13 (single flash, pause, three flashes) means that the airbag circuit has shorted to ground and Code 14 (single flash, pause, four flashes) means that the primary crash sensor circuit has shorted to ground.
Codes 21,22,23 and 24These codes are signaled by two flashes, a two-second pause and the number of flashes that corresponds to the second digit. Code 21 (double flash, pause, one flash) means the diagnostic monitor is not mounted properly. Code 22 (double flash, pause, two flashes) means the safing center output circuit has shorted to battery voltage, Code 23 (double flash, pause, three flashes) means the memory clear circuit is improperly grounded and Code 24 (double flash, pause, four flashes) means there is a system disarm failure or internal diagnostic monitor fault.
Codes 32,33,34 and 35These codes are signaled by three flashes, a two-second pause and the number of flashes that corresponds to the second digit. Code 32 (triple flash, pause, two flashes) means the driver side airbag has a circuit open or with high resistance, Code 33 (triple flash, pause, two flashes) means the passenger side airbag has a circuit open or with high resistance, Code 34 (triple flash, pause, four flashes) means the driver side airbag has a shorted circuit or one with low resistance and Code 35 (triple flash, pause, five flashes) means the passenger side airbag has a shorted circuit or one with low resistance.
Codes 41,42,43,44 and 45These codes are signaled by four flashes, a two-second pause and the number of flashes that corresponds to the second digit. Code 41 (four flashes, pause, one flash) means the right radiator primary crash sensor feed/return circuit is open, Code 42 (four flashes, pause, two flashes) means the left radiator primary crash sensor feed/return circuit is open, Code 44 (four flashes, pause, four flashes) means the right radiator crash sensor is not mounted properly and Code 45 (four flashes, pause, five flashes) means the left radiator crash sensor is not mounted properly.
Codes 51,52 and 53These codes are signaled by five flashes, a two-second pause and the number of flashes that corresponds to the second digit. Code 51 (five flashes, pause, one flash) means the airbag diagnostic monitor's internal fuse is blown, Code 52 (five flashes, pause, two flashes) means the back-up power supply has had a voltage boost fault and Code 53 (five flashes, pause, three flashes) means the front crash sensor has high resistance or the diagnostic monitor has failed.

Supplemental Restraint System (SRS) Warning LightThe supplemental restraint system (SRS) warning light is most commonly known as the airbag system light. This is a computer controlled system designed to deploy one or more driver, passenger, and side airbags. |

How to read air bag codes ?If SRS light is already flashing the vehicle may already be displaying fault codes, skip to step 5. Please Note:When code reading is finished the vehicle must be returned to normal operation mode. Refer to step 7.

- Remove ash tray from console panel
- Using a socket set, remove 4 hex head screws from console panel
- Pull console panel out of the two clips
- Remove connector from Passenger Airbag Disable module in console panel and take console panel to a work bench
- Remove 2 phillips head screws to remove the airbag key module
- Carefully unclip the plastic tabs that hold the airbag key module case together
- Remove circuit board from airbag key module housing
- To prepare the module housing I drilled a 1/4" hole through the clear lens allowing my particular LED to be attached through that hole
- Now carefully unsolder the blown light bulb
- Then you are able to solder on the new LED *polarity matters* with that in mind the negative on the circuit board is closest to the outer edge of the circuit board
- Reassemble the PAD Module and put it back into the console panel and then put everything back together on the dash in the reverse order of removal.

Disconnect and isolate the negative battery cable and wait at least 2 full minutes for the circuit to completely discharge before proceeding.
CAUTION:Failure to fully deplete the backup power supply could result in an accidental deployment and possible injury.
