HOW TO PROCEED WITH TROUBLESHOOTING |
CAUTION / NOTICE / HINT
NOTICE:
- Do not perform "Smart Code Reset" (all key ID erasure) until all malfunctions and symptoms have been confirmed and resolved. If all key ID erasure is performed without confirming or resolving malfunctions, key registration will be unable to be performed, resulting in unnecessary part replacement.
- Make sure that the smart key system has not been disabled by a customize setting.
HINT:
- Replace parts related to the wireless door lock control system and smart key system according to the inspection procedure.
- If the wireless door lock control system and smart key system do not operate, check the customize settings and make sure that the wireless door lock control system and smart key system are not disabled.
-
The wireless door lock control system and smart key system primarily use the following systems.
- Power door lock control system
- Wireless door lock control system
- Smart key system (for Entry Function)
-
Smart key system (for Start Function)
- Immobiliser function
- If 2 or more electrical key transmitter sub-assemblies are registered to the system, make sure to perform troubleshooting with all of them.
PROCEDURE

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 malfunctions 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 and time, frequency, whether the problem occurred recently or has been occurring for a long time
Where
Whether the problem occurs at specified location
Under what conditions?
Whether the doors were locked or unlocked, whether the engine switch was on (IG), whether the engine was running
How did it happen?
Ask the customer for details about the vehicle operating conditions, environment and malfunction.
