PREPARATION FOR THE INSPECTION MODE

Make sure the fuel remains approx. half amount [20 — 40 litres (5.3 — 10.6 US gal, 4.4 — 8.8 Imp gal)] and the battery voltage is 12 V or more.

Raise the vehicle using a garage jack and place on rigid racks or drive the vehicle onto free rollers.

Warning

• Before raising the vehicle, ensure the parking brake is applied.

• Do not use a pantograph jack in place of a rigid rack.

• Secure a rope or wire to the front and rear towing or tie-down hooks to prevent the lateral runout of front wheels.

• Do not abruptly depress/release the clutch pedal or accelerator pedal during works even when engine is operating at low speeds since this may cause vehicle to jump off free rollers.

• In order to prevent the vehicle from slipping due to vibration, do not place any wooden blocks or similar items between the rigid racks and the vehicle.

• Since the rear wheels will also rotate, do not place anything near them. Also, make sure nobody goes in front of the vehicle.

(A)

Rigid rack

(B)

Free rollers




Vehicle Diagnostic Interface

After clearing the memory, check for any remaining unresolved trouble data.

Warm up the engine.

Prepare the Vehicle Diagnostic Interface kit.

Connect the diagnosis cable to Vehicle Diagnostic Interface.

Connect the test mode connector (A) at the lower portion of instrument panel (on driver’s side).


Connect the Vehicle Diagnostic Interface to data link connector.

Data link connector is located in the lower portion of the instrument panel (on the driver’s side).


Connect the diagnosis cable to data link connector.

Important

Do not connect the scan tools except for Vehicle Diagnostic Interface and OBD-II general scan tool.


Turn the ignition switch to ON (engine OFF), and start the Vehicle Diagnostic Interface.

On «Main Menu» display screen, select the {2. Each System Check}.

On «System Selection Menu» display screen, select the {Engine Control System}.

Select the {OK} after the information of engine type is displayed.

On «Engine Diagnosis» display screen, select the {Dealer Check Mode Procedure}.

After the “Perform Inspection (Dealer Check) Mode?” is shown on display screen, select the {OK}.

Perform subsequent procedures as instructed on display screen.


• If trouble still remains in memory, the corresponding DTC appears on display screen.

Note
• For detailed operation procedure, refer to the Vehicle Diagnostic Interface OPERATION MANUAL.

• For details concerning the DTC, refer to the List of Diagnostic Trouble Code (DTC).

• Release the parking brake.

• The speed difference between front and rear wheels may light either the ABS warning light, but this indicates no malfunctions. When the engine control diagnosis is finished, perform the ABS memory clearance procedure of self-diagnosis system.



OBD-II GENERAL SCAN TOOL

After clearing memory, check for any remaining unresolved trouble data:

Warm up the engine.

Connect the test mode connector (A) at the lower side of instrument panel (on the driver’s side).


Connect the OBD-II general scan tool to its data link connector.

Important

Do not connect the scan tools except for Vehicle Diagnostic Interface and OBD-II general scan tool.



Start the engine.

Note
• Ensure the selector lever is placed in “P” position before starting. (AT models)

• Depress the clutch pedal when starting engine. (MT models)


Using the selector lever or shift lever, turn the “P” position switch and “N” position switch to ON.

Depress the brake pedal to turn brake switch ON. (AT models)

Keep the engine speed in 2,500 — 3,000 rpm range for 40 seconds.

Place the selector lever or shift lever in “D” position (AT models) or “1st” gear (MT models) and drive the vehicle at 5 to 10 km/h (3 to 6 MPH).

Note
• On AWD vehicles, release the parking brake.

• The speed difference between front and rear wheels may light ABS warning light, but this indicates no malfunctions. When the engine control diagnosis is finished, perform the ABS memory clearance procedure of self-diagnosis system.


Using the OBD-II general scan tool, check for DTC and record the result(s).

Note
• For detailed operation procedures, refer to the OBD-II General Scan Tool Instruction Manual.

• For details concerning DTC, refer to the List of Diagnostic Trouble Code (DTC).
