DOOR LOCK SYSTEM OPERATION RECORD

Purpose

  • Stores the record of the user's operation and the door lock system operation corresponding to the user's operation.

Function

  • The door lock system operation record is stored by the BCM and displayed using the Mazda Modular Diagnostic System (M-MDS).

  • The BCM stores the following when the front/rear door lock actuator operates.

    • Time and date

    • Part or function which output unlock signal

    • Part or function which output lock signal

    • Operated actuator

    • Vehicle condition

Construction

  • Based on the stored record, the BCM displays the following operation record on the Mazda Modular Diagnostic System (M-MDS) screen.

Operation

  • Based on the lock/unlock signal, the BCM sends an operation signal to the door lock actuator motor, and stores the operation record at the same time.

  • Because it takes time from when the front/rear door lock actuator motor operates until the lock/unlock is switched, the BCM may store the operation record before the lock/unlock switching is completed.

Fail-safe

  • Not applicable
