Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: ELECTRONICALLY CONTROLLED BRAKE SYSTEM (for Gasoline Model without Electric Parking Brake System TMC Made): DATA LIST / ACTIVE TEST; 2023 - 2025 MY Corolla Corolla Hatchback GR Corolla [09/2022 -        ]

DATA LIST / ACTIVE TEST

DATA LIST

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

HINT:

Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the GTS to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the GTS on.

(f) Enter the following menus: Chassis / Brake / Data List.

(g) According to the display on the GTS, read the Data List.

HINT:

A momentary interruption (open circuit) in the connectors and/or wire harness between the sensors and ECUs can be detected using the Data List function of the GTS.

CHECK FOR INTERMITTENT PROBLEMS

(a) Turn the ignition switch off.

(b) Connect the GTS to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the GTS on.

(e) Follow the directions on the GTS to display the Data List and select areas where momentary interruption should be monitored.

HINT:

  • A momentary interruption (open circuit) cannot be detected for 3 seconds after the ignition switch is turned to ON (initial check).
  • If Under intermittent remains displayed for one of the items on the GTS, check for continuity between the ECU and the item for which Under intermittent is displayed.
  • If a momentary interruption occurs and Under intermittent is displayed on the GTS, Under intermittent will remain displayed on the GTS for 1 second after the circuit returns to normal.

(f) Select the line graph display.

(g) Using the line graph, check whether the status is "Normal" or "Under intermittent".

OK:

Normal is displayed.

HINT:

If the display changes, this indicates that there has been a momentary interruption (open circuit) in the connector and/or wire harness. In this case, repair or replace the connectors and/or wire harnesses as one of them is faulty.

(h) While observing the screen, gently jiggle the connector or wire harness between the ECU and each sensors, or between ECUs.

OK:

Normal is displayed.

HINT:

  • If a momentary interruption occurs and Under intermittent is displayed on the GTS, Under intermittent will remain displayed on the GTS for 1 second after the circuit returns to normal.
  • If the display changes, this indicates that there has been a momentary interruption (open circuit) in the connector and/or wire harness. In this case, repair or replace the connectors and/or wire harnesses as one of them is faulty.

DATA LIST (STEERING ANGLE SENSOR)

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

HINT:

Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the GTS to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the GTS on.

(f) Enter the following menus: Chassis / Steering Angle Sensor / Data List.

(g) According to the display on the GTS, read the Data List.

ACTIVE TEST

HINT:

Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the GTS to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the GTS on.

(f) Enter the following menus: Chassis / Brake / Active Test.

(g) According to the display on the GTS, perform the Active Test.

NOTICE:

  • Although the Active Test automatically turns off the pump motor after approximately 5 seconds in order to protect the motor, do not operate the pump motor repeatedly without sufficient waiting time in between.
  • Although the Active Test automatically turns off each solenoid after approximately 2 seconds in order to protect the solenoid, do not operate the solenoids repeatedly without sufficient waiting time in between.
  • Do not depress the brake pedal when only the pressure release solenoids valves are ON.
