Lexus ES: Check For Intermittent Problems

CHECK FOR INTERMITTENT PROBLEMS

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 and saved, the operation history information could be lost.
  • The Operation History function uses the current system time of the Techstream and the time counter inside the controlling ECU to calculate the times shown in the operation history. For this reason, before reading the operation history, first make sure that the Techstream system clock is accurately set to the current time.
