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.

(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 battery
(a) Check whether the battery is in normal status.

Is the inspection result normal?

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

3 . Check starter and starter circuit

(a) Check whether the starer is damaged.
(b) Check whether the starter circuit is normal.

Is the inspection result normal?
YES>To step 4.

No >Maintenance related faults.

4 . heck the motor machinery
(a) Use an endoscope to observe the in-cylinder condition.
(b) Check engine internal parts, such as crankshaft, camshaft, timing mechanism and so
