WARNING LAMP ACTIVATION
WARNING LAMP BEHAVIOR AFTER IGNITION ON
As soon as the operating voltage is applied to the SRSCM ignition input, the SRSCM activates the warning lamp for a
bulb check.
The lamp shall turn on for 6 seconds during the initialization phase and be turned off afterward. However, in order to
indicate the driver, the warning lamp shall turn on for 6 seconds and off for one second then on continuously after the
operating voltage is applied if any active fault exists. 1. Active fault or historical fault counter is greater or equal to 10
2.Normal or historical fault counter is less than 10
SRSCM INDEPENDENT WARNING LAMP ACTIVATION
There are certain fault conditions in which the SRSCM cannot function and thus cannot control the operation of the
standard warning lamp. In these cases, the standard warning lamp is directly activated by appropriate circuitry that
operates independently of the SRSCM. These cases are:
1. Loss of battery supply to the SRSCM : warning lamp turned on continuously.
2. Loss of internal operating voltage : warning lamp turned on continuously.
3. Loss of Microprocessor operation : warning lamp turned on continuously.
4. SRSCM not connected : warning lamp turned on continuously through the shorting bar.
PASSENGER AIRBAG DEACTIVATION (PAD) LAMP OPERATION
The SRSCM is designed with circuitry and software to drive a PAD lamp, which is used for depowered airbag system.
For the PAD indicator circuitry to function properly, both the SRSCM and PAD indicator are sourced from the same
ignition line. After ignition on, the PAD indicator will be turned on for 4 seconds and off for 3 seconds during the
initialization phase. Thereafter the lamp will be turned on as long as the PAD switch is in the disabled position.
PASSENGER RESTRAINTS ACTIVATION WITH PAD SWITCH
The PAD switch affects the activation of the front passenger airbag only and the switch is controlled manually. The
PAD switch will be functioned as follows:
PAD Switch status PAD LampPAB
Phase- up ON → OFF Enable
Enabled position OFFEnable
Disabled position ONDisable
Fault Based on PABEnable
