If a trouble code is displayed during the DTC check, check the circuit listed for the code in the table.

HINT:
- 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 memory by the airbag sensor assembly center. 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 sensor assembly center may have failed.
- In the case of any malfunction concerning an open circuit, short to ground, or short to B+ due to an squib, other trouble codes may not be detected. In this case, repair the malfunction currently indicated and then perform malfunction diagnosis again.
- Mark in the check mode column:
- DTC is corresponding to the check mode.
- DTC is not corresponding to the check mode.

- When DTC B1650/32 is detected as a result of troubleshooting for the Supplemental Restraint System, perform troubleshooting for the occupant classification system as shown in the chart.
