AIRBAG SYSTEM DIAGNOSTIC TROUBLE CODE CHART
If a trouble code is displayed during the DTC check, check the trouble areas listed for the code in the table below (refer to the appropriate page).
Tech Tips
-
When the SRS warning light remains on and the 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 airbag ECU assembly. If the power source voltage returns to normal, the SRS warning light will automatically go off.
-
When 2 or more codes are indicated, the code with the lower number appears first.
-
If a code is not listed on the display chart, the airbag ECU assembly may have failed.
-
In the case of any malfunction concerning an open circuit, short to ground, or short to B+ due to a squib, other trouble codes may not be detected. In this case, repair the malfunction currently indicated and then perform malfunction diagnosis again.
