Toyota Tundra Service Manual: Check For Intermittent Problems



  • 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.

Operation History


Operation history: The main body ECU (multiplex network body ECU) records the power door lock control system operation history, which can be read out using the Techstream.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Main Body / Utility / Operation History.

(e) Following the instructions on the screen, save the operation history.
