3.The two coolant temperature sensors are installed to the heater inner. The sensor valves determine heater
operation.
4. One of the temperature sensors functions to prevent the heater from overheating.
If the sensor temperature valve exceeds 125°C, the fuel will be cut and the heater will be deactivated by the
determination of the overheating of the heater.
The other temperature sensor determines the operation mode of the fuel fired heater.The temperature of this
sensor enables to activate the heater at full load(5kw) or half load(2.5kw).
• The coolant temperature shown on the above Figure is the value of the inner sensor and the actual coolant
temperature is higher about 5°C ~7°C than the above value.
OPERATION
Switch on/ Operation start
The fuel fired heater is operated when the coolant temperature is below 68°C and the ambient temperature is below
2°C after starting the engine.
At this time, the glow plug and combustion air fan are operated first and after 30 seconds, the dosing pump is
operated with stopping the combustion fan for 3 seconds.
After that, the operation of the fan increases continuously until it approaches to full load within 56 seconds. If fuel
supply reaches to full load the glow plug does not operate and the operation of the fan reaches to full load.
After that the glow plug monitors ignition condition as a flame sensor for 45 seconds.
The above operation procedure is done automatically and in case the ignition fails, the above operation will be done
again automatically.
If the condition of ignition failure sustains continuously, fuel supply and fan operation will be stopped and error codes
will be stored to find cause of failure.
Generally, the cause of ignition failure during combustion is caused by the automatic re- operation of the above
procedure.
Operation for heating
The fuel fired heater operates at full load when the coolant temperature is below 68°C and the ambient temperature is
below 2°C after starting the engine.
It operates at half load when the coolant temperature is 74°C and it operates at idle mode when the coolant
temperature is 78°C.
The fuel fired heater during the transformation process does a cleaning function from the half mode to the idle mode.
At idle mode, all components do not work.
The fuel fired heater operating at idle mode turns into the half load when the coolant temperature is 74°C. At this time,
if the coolant temperature drops again below 68°C, the heater operates with full load and turns into the idle mode if
the temperature is 78°C.
This serial operating process is performed automatically.
Key switch off / Operation stop
The fuel fired heater ECU stops the operation of the fuel pump and cuts fuel supply when shutting off the engine
during the heater operation.
The heater conducts cleaning operation at this time.
This is a process of burning the fuel completely supplied in the heater inner.
In this process, the glow plug and combustion air fan are operated.

General
The supplemental restraint system (SRS) is designed to supplement the seat belt to help reduce the risk or severity of
injury to the driver and passenger by activating and deploying the driver, passenger, side airbag and belt pretensioner
in certain frontal or side collisions.
The SRS (Airbag) consists of : a driver side airbag module located in the center of the steering wheel, which contains
the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad
contains the folded cushion assembled with inflator unit ; side airbag modules located in the driver and passenger seat
contain the folded cushion and an inflator unit ; curtain airbag modules located inside of the headliner which contains
folded cushions and inflator units. The impact sensing function of the SRSCM is carried out by electronic
accelerometer that continuously measure the vehicle's acceleration and delivers a corresponding signal through
amplifying and filtering circuitry to the microprocessor.
SRSCM (SRS Control Module)
SRSCM will detect front impact with front impact sensor, and side impact with side impact sensor, and determine
airbag module deployment.
1. DC/DC converter: DC/DC converter in power supply unit includes up/down transformer converter, and provide
ignition voltage for 2 front airbag ignition circuits and the internal operation voltage of the SRSCM. If the internal
operation voltage is below critical value setting, it will perform resetting.
2. Safety sensor: Safety sensor is located in airbag ignition circuit. Safety sensor will operate airbag circuit at any
deployment condition and release airbag circuit safely at normal driving condition. Safety sensor is a double contact
electro - mechanical switch that will close detecting deceleration above certain criteria.
3. Back up power supply: SRSCM has separate back up power supply, that will supply deployment energy instantly in
low voltage condition or upon power failure by front crash.
4. Self diagnosis: SRSCM will constantly monitor current SRS operation status and detect system failure while vehicle
power supply is on, system failure may be checked with trouble codes using scan tool. (Hi- Scan)
5. Airbag warning lamp on: Upon detecting error, the module will transmit signal to SRSCM indicator lamp located at
cluster. MIL lamp will indicate driver SRS error. Upon ignition key on, SRS lamp will turn on for about six seconds.
6. Trouble code registration: Upon error occurrence in system, SRSCM will store DTC corresponding to the error.
DTC can be cleared only by Hi - Scan. However, if an internal fault code is logged or if a crash is recorded the fault
clearing should not happen.
7. Self diagnostic connector: Data stored in SRSCM memory will be output to Hi - Scan or other external output
devices through connector located below driver side crash pad.
8. Once airbag is deployed, SRSCM should not be used again but replaced.
9. SRSCM will determine whether passenger put on seat belt by the signal from built- in switch in seat belt buckle, and
deploy front seat airbag at each set crash speed.
10. Side airbag deployment will be determined by SRSCM that will detect satellite sensor impact signal upon side
crash, irrespective to seat belt condition.

DESCRIPTION
The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an
event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to
deploy the restraint system or not. After determining that pretensioners and/or airbag deployment is required, the
SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment. The SRSCM
determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact
sensors and other components in conjunction with a safing function. The SRSCM will not be ready to detect a crash or
to activate the restraint system devices until the signals in the SRSCM circuitry stabilize. It is possible that the SRSCM
could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-
out is completed. The SRSCM must perform a diagnostic routine and light a system readiness indicator at key - on. The
system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator
in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the
restraint control system.
