DIAGNOSIS-ENGINE CONTROL SYSTEM                             62-611

                 Is the inspection result normal?
                 YES> To step 11。
                 No > Perform the alignment operation of the timing belt or change the timing belt.

                 11.    Check the motor machinery
                                                                                                                    62
                 (a).   Use an endoscope to observe the in-cylinder condition.
                 (b).   Observe and reflect the voltage changes.
                 (c).   Dismantle and repair the motor internal fault:clean the carbon or disassemble
                        and check the motor cylinder cover. Check the valve, intake manifold has carbon
                        deposition. Such as: the gap between the piston ring and the cylinder is too tightly
                        loosed, cylinder pad leaks, valve tube loose, valve does not close well, and valve
                        has carbon deposition.


                 Is the inspection result normal?
                 YES> To step 12。
                 No > Repair the internal machinery fault of the motor.


                 12.    Replace  ECU.


                 (a).   Replace  ECU.。
                 (b).   Check the data flow of the engine, and make sure the engine phenomenon does not
                        exist, the system is normal.
