Important Points in the Symptom Simulation Test:
In the symptom simulation test, the problem symptoms should of course be confirmed, but the problem area or parts must also be found out. To do this,
narrow down the possible problem circuits according to the symptoms before starting this test and connect a tester beforehand. After that, carry out the
symptom simulation test, judging whether the circuit being tested is defective or normal and also confirming the problem symptoms at the same time.
Refer to the problem symptoms table for each system to narrow down the possible causes of the symptom.
