This malfunction is not stored in memory by the center airbag sensor assembly and if the power source voltage returns to normal, after approx. 10 seconds the SRS warning light will automatically go out. *2 • Code 22 is recorded when a malfunction occurs in the SRS warning light system. If an open malfunction occurs in the SRS warning light system, the SRS warning light does not light up, so that until the malfunction is repaired, the diagnostic trouble codes (including code 22) cannot be confirmed. • When 2 or more codes are indicated, the lowest numbered code will appear first. • If a code not listed on the chart is displayed, the center airbag sensor assembly is faulty.
