2-3 Check the preparation of the ignition timing engine:
2-3-1 Before checking the ignition timing, make preparations of the engine, check the
discharge control plate of this vehicle or the test procedure and technical requirement for
the ignition timing in the repair manual. The discharge control plate of the vehicle is inside
the engine chamber, the usual position is: the back of the engine hood, the engine bulk-
head, the top of the valve chamber cover or near the engine hood lock.
