There are many ways to conduct an airbag check. Being sure your airbag is working properly can help reassure you and your passengers feel safe. So, confirm if your airbag system is operating correctly.
Airbag Diagnostic Tests
Most vehicles today can do an airbag diagnostic test. The test checks to confirm if all the sensors and circuits of the airbag are functioning. If the system detects any issues, it gives you a signal through the airbag indicator by flashing the light many times, giving you the specific problem the test has detected. These flashes are codes, with its own meaning.
Airbag Diagnostic Codes
the airbag codes are usually double digit numbers. To read the codes, you have to count the number of times the light flashes, wait for the pause and count the flashes again. For example, two flashes, a pause and four flashes mean that your airbag system’s problem is a code 24.
Code 12 shows your battery voltage is low, while 13 indicates that the airbag circuit is shorted or grounded. Code14 indicates the short or ground is on the primary crash sensor circuit. You need to check if the airbag is mounted normally to your car if you read code 21. Code 22 shows the safing sensor output is shorted to battery voltage, while 23 means the safing sensor input feed or return circuit is open. Code 24 means the output feed is open. Codes 32 to 35 pertain to problems with the airbags on the driver and passenger sides. Codes 41 to 45 pertain to problems with the RH and LF primary crash sensor. Airbag diagnostic codes go up to 53.
It is important to familiarize yourself with these codes so you get the appropriate airbag repair services.
