HINT:

When the SRS warning light remains lit up and the DTC is the normal code, this means a voltage source
drops.
This malfunction is not stored in memory by the airbag sensor assembly and if the power source volt-
age returns to normal, the SRS warning light will automatically go out.

When 2 or more codes are indicated, the codes will be displayed in numeral order starting from the
lowest numbered code.

If a code not listed on the chart is displayed, the airbag sensor assembly is faulty.
