CUSTOMER PROBLEM ANALYSIS |
- When troubleshooting, check 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?

3. |
INSPECT AUXILIARY BATTERY |
(a) Measure the auxiliary battery voltage with the ignition switch off.
Standard voltage:
11 to 14 V
(b) Visually inspect for blown fuses, an open or short in a wire harness or improperly connected connectors, etc.
OK:
Not abnormal

4. |
CHECK CABIN |
(a) Check that condensation is not likely to occur in the cabin and that the temperature is not -20°C (-4°F) or lower, or 65°C (149°F) or higher.
HINT:
- A humid cabin and a rapid change in temperature may lead to condensation. Condensation in the cabin may cause a short circuit.
- The audio and visual system may not operate normally when the temperature is -20°C (-4°F) or lower, or 65°C (149°F) or higher.
