                 Diagnosis Procedure

                 1 .    Check the engine data
                 (a)    Ignition switch: OFF.
                 (b)    Connect the diagnosis tool with the fault diagnosis connector (16 pins) on the lower
                        left of the dashboard.
                 (c)    Ignition switch: ON, and start the diagnostic tool.
                 (d)    Read the motor data shown on the diagnostic tool.
                 Check whether the data flow is normal or not.

                 YES>To step 2.
                 No >Maintenance related faults.

                 2 .    Check cooling system

                 (a)    Check whether cooling system leaks or not.
                 Is the inspection result normal?

                 YES>To step 3.
                 No >Maintenance related faults.


                 3 .    Check radiator and radiator cover
                 (a)    Check whether radiator and radiator cover leak or not.
                 Is the inspection result normal?

                 YES>To step 4.
                 No >Maintenance related faults.

                 4 .    Check cooling pipe
                 (a)    Check whether cooling pipe leaks or not.

                 Is the inspection result normal?

                 YES>To step 5.
                 No >Maintenance related faults.

                 5 .    Check EGR cooler

                 (a)    Check whether EGR cooler leaks or not.
