AIRBAG SYSTEM DIAGNOSTIC TROUBLE CODE CHART

If a DTC is displayed during the DTC check, check the circuit listed for the DTC in the table below (proceed to the page listed for that circuit).

Tech Tips


  • If no DTC is indicated despite the SRS warning light blinking, a voltage source drop is likely to have occurred. This malfunction is not stored in the memory of the center airbag sensor assembly. When the power source voltage returns to normal, the SRS warning light will automatically turn off.

  • If a DTC is not listed on the display chart, the center airbag sensor assembly may have malfunctioned.

  • In the case of any malfunctions concerning open circuits, shorts to ground, or shorts to B+ due to squibs, other DTCs may not be set. In this case, repair the malfunction currently indicated and then perform malfunction diagnosis again.

  • Mark in the check mode column:

    ○:DTC corresponds to check mode.

    -:DTC does not correspond to check mode.
