DATA LIST / ACTIVE TEST
DATA LIST (ELECTRONICALLY CONTROLLED BRAKE SYSTEM)
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:
(g) According to the display on the GTS, read the 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 / 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/EPB / Active Test.
(g) Perform the Active Test to check for incorrect operation or to narrow down malfunctioning areas.

---|---|---|---|---|
EBS Relay |
Emergency brake signal operation |
Relay OFF / ON |
Vehicle condition: Vehicle stopped HINT: To protect this Actuator and Solenoid, this test will only last 5 seconds. |
w/ Emergency Brake Signal Whether the hazard warning lights blink when the EBS Relay is ON can be confirmed |
ABS Solenoid |
Pressure holding solenoid (SFRH, SFLH, SRRH, SRLH) Pressure reduction solenoid (SFRR, SFLR, SRRR, SRLR) |
Solenoid Start (Activate) Solenoid SFRH / SFLH / SRRH / SRLH / SFRR / SFLR / SRRR / SRLR |
Vehicle condition:
HINT: To protect actuator and Solenoid(s), this test will continue for 25 seconds. |
Refer to on-vehicle inspection for the brake actuator (for Gasoline Model)* |
VSC Solenoid |
Master cylinder cut solenoid (SMF (SM1), SMR (SM2)) Reservoir cut solenoid ((SRCF (SRC1), SRCR (SRC2)) |
Solenoid Start (Activate) Solenoid SMF / SMR / SRCF / SRCR |
Vehicle condition:
HINT: To protect actuator and Solenoid(s), this test will continue for 25 seconds. |
Check that the GTS display for the solenoid (SM1, SM2, SRC1 or SRC2) changes to ON/OFF during Solenoid Start (Activate) |
Motor Relay |
ABS motor relay |
Relay OFF / ON |
Vehicle condition: Vehicle stopped HINT: To protect this Actuator and Solenoid, this test will only last 5 seconds. |
Refer to on-vehicle inspection for the brake actuator (for Gasoline Model)* |
Stop Lamp Relay |
Stop light control relay (Stop light switch assembly) |
Relay OFF / ON |
Vehicle condition: Vehicle stopped HINT: To protect this Actuator and Solenoid, this test will only last 5 seconds. |
With the brake pedal released, check that the stop lights illuminate and the value of Stop Light Relay on the GTS changes to ON when Stop Lamp Relay is ON |
