- If a trouble code is displayed during the DTC check, inspect the trouble areas listed for that code. For details of the code, refer to DTC table.
- When the SRS warning light remains on and the DTC output is the normal system code, a voltage source drop is likely to occur This malfunction is not stored in the memory by the center airbag sensor. 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 not listed in the chart is displayed, the center airbag sensor may have a malfunction.
- If a DTC is output indicating a short to ground, short to B+ or open in an airbag squib circuit area, other DTCs may not be output. First replace or repair the malfunctioning area indicated by the current DTC, and then check for DTCs again to output the other DTCs.
- Mark in the check mode column.
*1: DTC is not corresponding to the check mode.
*2. DTC is corresponding to the check mode.
