HINT:
When the SRS warning light remains on and the DTC is the normal code, a voltage source drop is sus-
pected.
This malfunction is not stored in memory by the airbag sensor assy center and if the power source
voltage returns to normal, the SRS warning light will automatically go off.
If a code not listed on the displayed chart, the airbag sensor assy center may be failed.
In the case of any malfunction concerning any open circuit, short to ground, or short to B+ due to any
squib, another malfunction code may not be detected. In this case, repair the malfunction currently
indicated and then perform malfunction diagnosis again. Another malfunction code may then be de-
tected.
