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) Enter the following menus: Chassis / Brake Booster / Data List.
(f) Enter the following menus: Chassis / Brake/EPB* / Data List.
*: Electric Parking Brake System
(g) Turn the GTS on.
(h) According to the display on the GTS, read the Data List.

CHECK FOR INTERMITTENT PROBLEMS
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.
(a) Turn the ignition switch off.
(b) Connect the GTS to the DLC3.
(c) Turn the ignition switch to ON.
(d) Enter the following menus: Chassis / Brake/EPB* / Data List.
*: Electric Parking Brake System
(e) Turn the GTS on.
(f) Follow the directions on the GTS to display the Data List and select areas where momentary interruptions 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).

(g) Push the line graph button to display the line graph.
(h) Check for intermittent shorts, etc.
OK:
Normal is displayed.
HINT:
If "Under intermittent" remains displayed on the GTS, measure the resistance between the skid control ECU (brake actuator assembly) and each sensor or the hybrid vehicle control ECU.
(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 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.
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/EPB* / Active Test.
*: Electric Parking Brake System
(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.
