2.CUSTOMER PROBLEM ANALYSIS

HINT:

In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.

Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.

The following 5 items are important points for problem analysis:

What	Vehicle model, system name
When	Date, time, occurrence frequency
Where	Road conditions
Under what conditions?	Driving conditions, weather conditions
How did it happen?	Problem symptoms

Result:

Proceed to
NEXT

3.PRE-CHECK

Measure the battery voltage.

Standard Voltage:: 11 to 14 V

If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

Check the fuses and relays.

Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.
