HOW TO PROCEED WITH TROUBLESHOOTING

CAUTION / NOTICE / HINT

HINT:

  • Use this procedure to troubleshoot the theft deterrent system.
  • *: Use the Techstream.

CUSTOMER PROBLEM ANALYSIS 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

Vehicle model, system name

When

Date, time, occurrence frequency, whether the problem occurred recently or has been occurring for a long time

Where

Whether the problem occurs at a specific location

Under what conditions?

Whether the doors were locked or unlocked, whether the ignition switch was ON, whether the engine has started.

How did it happen?

READ AND SAVE OPERATION HISTORY

NOTICE:

  • If the vehicle or vehicle controls are operated (for example, during initial inspection when the vehicle is brought in for repair) before operation history has been read and saved, the operation history information could be lost.
  • The operation history function uses the current system time of the Techstream and the time counter inside the controlling ECU to calculate the times shown in the operation history. For this reason, before reading the operation history, first make sure that the Techstream system clock is accurately set to the current time.

(a) Read and save operation history using the Techstream.

PRE-CHECK

(a) 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.

(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.
