2007 > 2.7L V6 GASOLINE >
DESCRIPTION
1.Engine is hard to start or does not start at all.
2. Unstable idle.
3. Poor driveability
If any of the above conditions are noted, first perform a routine diagnosis that includes basic engine checks (ignition
system malfunction, incorrect engine adjustment, etc.). Then, inspect the Gasoline Engine Control system components
with the HI- SCAN (Pro).
a. Before removing or installing any part, read the diagnostic trouble codes and then disconnect the battery
negative ( - ) terminal.
b. Before disconnecting the cable from battery terminal, turn the ignition switch to OFF. Removal or connection
of the battery cable during engine operation or while the ignition switch is ON could cause damage to the
ECM.
c. The control harnesses between the ECM and heated oxygen sensor are shielded with the shielded ground
wires to the body in order to prevent the influence of ignition noises and radio interference. When the shielded
wire is faulty, the control harness must be replaced.
d. When checking the generator for the charging state, do not disconnect the battery '+' terminal to prevent the
ECM from damage due to the voltage.
e. When charging the battery with the external charger, disconnect the vehicle side battery terminals to prevent
damage to the ECM.

Faults with the following items will illuminate the MILa. Heated oxygen sensor (HO2S)
b. Mass Air Flow sensor (MAFS)
c. Throttle position sensor (TPS)
d. Engine coolant temperature sensor (ECTS)
e. Idle speed control actuator (ISCA)
f. Injectors
g. ECM
Refer to "INSPECTION CHART FOR DIAGNOSTIC TROUBLE CODES (DTC)" for more information.
1. After turning ON the ignition key, ensure that the light illuminates for about 5 seconds and then goes out.
2. If the light does not illuminate, check for an open circuit in the harness, a blown fuse or a blown bulb.
Self-Diagnosis
If a sensor connector is disconnected with the ignition switch turned on, the diagnostic trouble code (DTC) is
recorded. In this case, disconnect the battery negative terminal ( - ) for 15 seconds or more, and the diagnosis
memory will be erased.
THE RELATION BETWEEN DTC AND DRIVING PATTERN IN EOBD SYSTEM
1.When the same malfunction is detected and maintained during two sequential driving cycles, the MIL will
automatically illuminate.
2. The MIL will go off automatically if no fault is detected after 3 sequential driving cycles.
3. A Diagnostic Trouble Code(DTC) is recorded in ECM memory when a malfunction is detected after two sequential
driving cycles. The MIL will illuminate when the malfunction is detected on the second driving cycle.
If a misfire is detected, a DTC will be recorded, and the MIL will illuminate, immediately after a fault is first
detected.

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.

DIAGNOSIS AND TESTING - POWER TAILGATE SYSTEM
The power tailgate system is a complex system containing many components. In order to perform conclusive testing,
or receive outputs the power tailgate control module must be checked.
The most reliable, efficient, and accurate means to diagnose the power tailgate system requires the use of a scan tool
and the proper Body Diagnostic Procedures manual. The scan tool can be used to observe current switch status
recorded in the power tailgate control module to help the technician diagnose an inoperative switch.
Before any testing of the power tailgate system is attempted, the battery should be fully charged, all power tailgate
system inhibitors read and understood (Refer to power tailgate system description for list).
Following are quick reference diagnostic tables to help when diagnosing and testing the power tailgate system.
