INSPECTION PROCEDURE
HINT:
DTC P0325 is for the bank 1 knock sensor circuit.
DTC P0330 is for the bank 2 knock sensor circuit.
Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records
the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can
help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel
ratio was lean or rich, as well as other data from the time when a malfunction occurred.
1 Connect OBD II scan tool or hand-held tester, and check knock sensor circuit.
PREPARATION:
(a) Connect the OBD II scan tool or hand-held tester to the
DLC3.
(b) Disconnect the EC1 connector.
(c) Connect the terminals of the disconnected EC1 male con-
nector and EC1 female as follows.
Male connector eFemale connector
Terminal 2 e Terminal 3
Terminal 3 e Terminal 2
(d) Turn ignition switch ON and push the OBD II scan tool or
hand-held tester main switch ON.
(e) After the engine is warmed up, perform quick racing to
4,000 rpm 3 times.
CHECK:
Check the DTC.
RESULT:
Type IDTC same as when vehicle brought in
P0325 " P0325 or P0330 " P0330

2. CATALYST MONITOR (O2S TYPE)
(a) Preconditions
The monitor will not run unless:
MIL is OFF.
Engine Coolant Temperature (ECT) is 75°C (167°F) or greater.
Intake Air Temperature (IAT) is -10°C (14°F) or greater
NOTICE:
The readiness test can be completed in cold ambient conditions (less than -10°C / 14°F), if the drive
pattern is repeated a second time after cycling the ignition off.
(b) Drive Pattern
(1) Connect the OBD II scan tool to the DLC3 to check monitor status and preconditions.
(2) Drive the vehicle at 40 to 55 mph (64 to 88 km/h) for approximately for 3 minutes.
NOTICE:
Drive with smooth throttle operation and avoid sudden acceleration.
If IAT is less than 10°C (50°F) when engine was started, drive the vehicle at 40 to 55 mph (64 to 88
km/h) for additional 4 minutes.
(3) Drive the vehicle at 35 to 45 mph (56 to 72 km/h) for approximately 7 minutes.
NOTICE:
Drive with smooth throttle operation and avoid sudden deceleration as much as possible with the
throttle fully closed.
(4) If readiness status does not switch to complete, make sure that the preconditions are met and
the ignition switch is turned OFF and then repeat steps (2) and (3).
(5) Release pressure in the fuel tank by removing and then reinstalling the fuel tank cap.
(6) Start the engine and immediately begin driving as directed.

242SRS
*The SRS airbag are provided for the driver and front passenger. The SRS airbags have been designed to help reducing
the shocks to the heads and chests of the driver and front passenger in the event of a severe frontal impact collision as
supplements to the seat belts.
This system is a 3-sensor type airbag system to detect the impact during a front collision using the center airbag sensor
assembly and airbag sensor front LH, RH, and to make the airbag system and pretensioner operate as well.
*In this system, a front side collision is detected by the side airbag sensor front LH, RH in order to simultaneously deploy
the side and curtain shield airbags. A rear side collision is detected by the side airbag sensor rear LH, RH in order to
deploy only the curtain shield airbag.
*Roll sensing of curtain shield airbags control has been adopted in order to deploy the curtain shield airbags and the
pretensioners for the driver and front passenger, in the event that the vehicle rolls over.
A roll sensing of curtain shield airbags cutoff SW is provided on the driver side of the instrument panel to enable the driver
to disable this system.
*Dual-stage SRS airbags system, that controls the airbag inflating output optimum by judging the extent of impact and seat
position (Driver seat), has been used for the driver and front passenger airbags.
*In accordance with the adoption of the dual-stage SRS airbag system, a seat position sensor has been established for the
driver seat.
*This system has adopted a fuel cut control that stops the fuel pump when the airbag is deployed.
