SRSCM Independent Lamp Activation

The SRS malfunction indicator lamp (MIL) is located on the cluster giving information of SRS operating conditions by the control signals from SRSCM.
There are certain fault conditions in which the SRSCM (SRS Control Module) cannot function and thus cannot control the operation of the lamp. In these cases, the lamp is directly activated by appropriate circuitry that operates independently of the SRSCM, as follow:

1. Loss of ignition voltage supply to the SRSCM : lamp turned on continuously.
2. Loss of internal operating voltage : lamp turned on continuously.
3. SRSCM not connected: lamp turned on through shorting bar in wiring harness connector.
