Hint:
Using the intelligent tester's data list allows switch, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save time.

Key reminder buzzer does not sound
Description
The key reminder warning buzzer sounds when the driver side door is opened while the ignition switch is in the lock or acc positions. The key reminder warning buzzer is activated when the main body ecu sends a key switch signal and driver side courtesy switch signal to the combination meter.
Hint: since the key reminder warning system has functions that use can communication, first confirm that there is no malfunction in the communication system by inspecting the can communication functions in accordance with the "how to proceed with troubleshooting" procedures. Then, conduct the following inspection procedure.
