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 entry and start system has not been disabled by a customize setting.
Replace parts related to the wireless door lock control system and smart entry and start system according to the inspection procedure.
If the wireless door lock control system and smart entry and start system do not operate, check the customize settings and make sure that the wireless door lock control system and smart entry and start system are not disabled.

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 ignition switch was ON, whether the hybrid control system was starting |
| How did it happen? | Ask the customer for details about the vehicle operating conditions, environment and malfunction. |

Measure the auxiliary battery voltage with the ignition switch off.
11 to 14 V
A simple method to determine whether the auxiliary battery is depleted is to operate the horn.
If the auxiliary battery voltage is below 11 V, recharge or replace the auxiliary battery.
Check for blown fuses, open or shorted wire harnesses, improperly connected connectors and other problems in areas that can be visually inspected.
Check the connection of each connector and check them for deformation or damage.
