Component Description






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





Clock Spring (In Multi-function Switch)
The steering wheel must be fitted correctly to the steering column with the clock spring at the neutral position, otherwise cable disconnection and other troubles may result.





Air-Bag Module (With Airbag)
1. When removing the air-bag module or handling a new air-bag module, it should be placed with the pad top surface facing up. In this case, the twin-lock type connector lock lever should be in the lock state and care should be taken to place it so the connector will not be damaged. And do not store a steering wheel pad on top of another one. (Storing the pad with its metallic surface up may lead to a serious accident if the airbag inflates for some reason.)
2. Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is very dangerous.)
3. Store the air-bag module where the ambient temperature remains below 93°C (200°F), without high humidity and away from electrical noise.
4. When using electric welding, first disconnect the airbag connector (red color and 2 pins) under the steering column near the MULTI-FUNCTION SWITCH connector before starting work.





SRSCM (SRS Control Module)
Install the SRSCM with the arrow on the SRSCM facing toward the front of the vehicle.
