When terminals Tc and E1 of the DLC1 or DLC2 are connected, the diagnostic trouble code is displayed by the blinking of the SRS warning light.\nThe SRS warning light circuit is equipped with an electrical connection check mechanism which detects when the connector to the center airbag sensor assembly is not properly connected.\nIf the connector to the center airbag sensor assembly is not properly connected, the SRS warning light will not light up.\nDiagnostic trouble 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.\n\nDTC No. | Diagnosis\n22 | • Open circuit in SRS warning light system.\n     • Center airbag sensor assembly malfunction.\n\nWIRING DIAGRAM\n\nCenter Airbag Sensor
