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

(b) Push the line graph button to display the line graph.
(c) 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 and each sensor, hybrid vehicle control ECU or airbag ECU assembly.
(d) While observing the screen, gently jiggle the connectors or wire harnesses between the ECUs and 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 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.
(a) Operate the GTS to 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) According to the display on the GTS, perform the Active Test.
NOTICE:
- Although the Active Test automatically turns off the actuator after approximately 5 seconds in order to protect the actuator, do not operate the actuator repeatedly without sufficient waiting time in between.
- To protect the solenoids, 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.
