Toyota CH-R Service Manual: Operation History List

OPERATION HISTORY LIST

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 out and saved, the operation history information could be lost.
  • The function "Read operation history" uses the current system time setting inside the Techstream and the time counter inside the controlling ECU to calculate the timings shown in the operation history. For this reason, before reading out the operation history, first make sure that the Techstream system clock is accurately set to the current time.
  • Door lock/unlock operation using the door lock knob is not recorded in operation history.
  • When the a door is not fully closed, so that door lock cannot be performed and the door not fully closed warning buzzer sounds, the operation is not recorded in the lock operation history.
