Toyota 4Runner: Vehicle Control History

VEHICLE CONTROL HISTORY

1. Function Overview

(a) The vehicle control history is a function that records control data (record data) when triggered by specific vehicle behavior. When DTCs are not detected according to information provided by customers, by checking the vehicle control history, it is possible to gain a quantitative grasp on diagnostic information and the history can be used as a reference to proceed with malfunction diagnosis.

(b) The vehicle control history is recorded in different storage areas designated by trigger group and it is possible to save up to 140 items in total. If storage space runs out, the data is cleared from the oldest data first for the respective storage area and new data is recorded.

(c) Each trigger receives time information from the main body ECU (time elapsed since ignition switch turned to ON) or the navigation system* (absolute time).

  • *: Only for factory-installed navigation systems (factory option)

(d) Data is recorded in the airbag sensor assembly EEPROM. Even if the battery negative terminal is disconnected, the vehicle control history does not disappear. Also, data cannot be cleared using the Techstream.

2. Notices for Use

(a) Vehicle control history is used as support information during malfunction diagnosis for each system and cannot be used to determine the actual cause of a problem.

(b) Judgment of each trigger is based on signals from sensors and actuators (recognition value of each ECU). Therefore, make sure to inspect and adjust systems related to each trigger when using the vehicle control history.

Basic Flow


3. Trigger Item

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch ON.

(c) Using the Techstream, enter the following menus: Body Electrical / SRS Airbag / Utility / Vehicle Control History.

Remarks

Engine control/Hybrid control/Automatic transmission

Area 1

(Approximately 60 times)

Accelerator pedal opening angle signal is high during low speed

An accelerator high position signal condition continues for a certain period of time while in the low speed range.

-

Accelerator high position in mid to high speed

An accelerator high position signal condition continues for a certain period of time while in the mid to high speed range.

-

Area 2

(Approximately 12 times)

Accelerator pedal opening angle signal is high immediately after brake pedal is released

An accelerator high position signal is received while in the low speed range after there is a change from brake input condition to brake and accelerator pedal released condition.

-

Area 3

(Approximately 40 times)

Accelerator pedal opening angle is medium or higher immediately after shifting to R

An accelerator mid to high position signal is received while in the low speed range immediately after the shift lever is moved to R during an accelerator low position signal condition.

Excluding hybrid vehicles

Accelerator pedal opening angle is medium or higher immediately after shifting to forward position

An accelerator mid to high position signal is received while in the low speed range immediately after the shift lever is moved to a forward position (a position other than P, N or R) during an accelerator low position signal condition.

Excluding hybrid vehicles

Accelerator pedal opening angle is medium or higher immediately after shifting to driving position

An accelerator mid to high position signal is received while in the low speed range immediately after the shift lever is moved to a driving position (a position other than P or N) during an accelerator low position signal condition.

Area 3

(Approximately 40 times)

Forward position signal input during medium or higher accelerator signal input
