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 Techstream 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 engine switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the engine switch on (IG).

(e) Turn the Techstream on.

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

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

OK:

Normal is displayed.

HINT:

If "Under intermittent" remains displayed on the Techstream, measure the resistance between the skid control ECU (brake actuator assembly) and the each sensor or ECM.

(i) 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 Techstream, Under intermittent will remain displayed on the Techstream 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.

ACTIVE TEST

HINT:

Using the Techstream 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 engine switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the engine switch on (IG).

(e) Turn the Techstream on.

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

(g) Perform the Active Test to check for incorrect operation or to narrow down malfunctioning areas.

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.
  • Do not operate more than one solenoid at the same time, except for when operating the pressure hold solenoid and pressure release solenoid of the same wheel.
