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 (refer to the appropriate page).
Tech Tips
-
When the SRS warning light remains on and a DTC is output (or the normal system code is output), this may be due to a source voltage drop. This malfunction is not stored in memory by the center airbag sensor assembly. If the power source voltage returns to normal, the SRS warning light will automatically go off.
-
When 2 or more DTCs are indicated, the DTC with the lower number appears first.
-
If a DTC is not listed on the display chart, the center airbag sensor assembly may be malfunctioning.
-
In the case of any malfunction concerning an open circuit, short to ground, or short to B+ due to a squib, other DTCs may not be detected. In this case, repair the malfunction currently indicated and then perform malfunction diagnosis again.
