ON-VEHICLE INPECTION
a.Check that the battery cables are connected to the correct terminals.
b. Disconnect the battery cables when the battery is given a quick charge.
c. Never disconnect the battery while the engine is running.
CHECK BATTERY VOLTAGE
1.If 20 minutes have not passed since the engine was stopped, turn the ignition switch ON and turn on the electrical
system (headlamp, blower motor, rear defogger etc.) for 60 seconds to remove the surface charge.
2. Turn the ignition switch OFF and turn off the electrical systems.
3. Measure the battery voltage between the negative ( - ) and positive (+) terminals of the battery.
Standard voltage : 12.5 ~ 12.9V at 20°C(68°F)
If the voltage is less than specification, charge the battery.

Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should
be replaced.
VISUALLY CHECK ALTERNATOR WIRING AND LISTEN FOR ABNORMAL NOISES
1.Check that the wiring is in good condition.
2. Check that there is no abnormal noise from the alternator while the engine is running.
CHECK DISCHARGE WARNING LIGHT CIRCUIT
1.Warm up the engine and then turn it off.
2. Turn off all accessories.
3. Turn the ignition switch "ON". Check that the discharge warning light is lit.
4. Start the engine. Check that the light is lit.
If the light does not go off as specified, troubleshoot the discharge light circuit.
INSPECT CHARGING SYSTEM
VOLTAGE DROP TEST OF ALTERNATOR OUTPUT WIRE
This test determines whether or not the wiring between the alternator "B" terminal and the battery (+) terminal is good
by the voltage drop method.
PREPARATION

2007 > 2.7L V6 GASOLINE >
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.

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

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.
