How To Proceed With Troubleshooting
CAUTION / NOTICE / HINT
HINT:
Use the following procedure to troubleshoot the lighting system.
PROCEDURE
| 1. | VEHICLE BROUGHT TO WORKSHOP |
|
| 2. | CUSTOMER PROBLEM ANALYSIS AND SYMPTOM CHECK |
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
Toyota Prius 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
|
| 3. | PRE-CHECK |
(a) Measure the auxiliary battery voltage with the ignition switch off.
Standard Voltage:
11 to 14 V
If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding to the next step.
(b) Check the fuses and relays.
(c) Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.
|
| 4. | CHECK COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM* |
(a) Using the GTS, check for CAN communication system DTCs.

Diagnosis System
DIAGNOSIS SYSTEM
DESCRIPTION
(a) Lighting system data can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the GTS to check for malfunctions and perform repairs.
CHECK DLC3
(a) Check the DLC3.

DATA LIST / ACTIVE TEST
DATA LIST
NOTICE:
In the following table, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
HINT:
Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
(a) Read the Data List according to the display on the GTS.
