See step  2

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Start the engine.
4. Enter the following menus: Chassis / ABS/VSC/TRAC / Data List / Master Cylinder Sensor.
5. Read the value displayed on the Techstream.

   Techstream Display	Measurement Item/Range	Normal Condition
   Master Cylinder Sensor	Master cylinder pressure sensor reading/ Min.: 0.00 V, Max.: 5.00 V	Brake pedal released: 0.30 to 0.90 V Reading increases when brake pedal is depressed

6. Check that the brake fluid pressure value of the "Master Cylinder Sensor" observed on the Techstream changes when the brake pedal is depressed.

   OK

   When the pedal is depressed, the voltage displayed on the Techstream increases.

Result: 

NG 

INSPECT BRAKE ACTUATOR ASSEMBLY 

Result: 

OK 

See step  3

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Enter the following menus: Powertrain / Engine and ECT / Data List / Stop Light Switch and ST1.
4. Check the Data List indication when the brake pedal is depressed and released.

   OK

   Techstream Display	Condition	Specified Condition
   Stop Light Switch	Brake pedal released	OFF
   	Brake pedal depressed	ON
   ST1	Brake pedal released	OFF
   	Brake pedal depressed	ON

Result: 

NG 

INSPECT STOP LIGHT SWITCH ASSEMBLY 

(Refer to ON-VEHICLE INSPECTION [09/2014 - 10/2015] )

Result: 

OK 

See step  4

1. Inspect and adjust the brake pedal support assembly (Refer to ADJUSTMENT [09/2014 - 10/2015] ).

   HINT: 

   If the stop light switch turns on too late, the start of brake override system control may be delayed; if it turns on too soon, brake override system control may begin too early. Therefore, it is necessary to conduct inspection of the brake pedal and stop light switch assembly.

Result: 

NG 

REPAIR OR REPLACE BRAKE PEDAL 

(Refer to REMOVAL [09/2014 - ] )

Result: 

OK 

See step  5

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Enter the following menus: Powertrain / Engine and ECT / Data List / Accel Sens. No. 1 Volt % and Accel Sens. No. 2 Volt %.
4. Read the value displayed on the Techstream.

   OK

   Techstream Display	Condition	Specified Condition
   Accel Sens. No. 1 Volt %	Accelerator Pedal Released → Depressed → Released	Values smoothly change following accelerator pedal operation
   Accel Sens. No. 2 Volt %

   HINT: 

   For numerical values of Accel Sens. No. 1 Volt % and Accel Sens. No. 2 Volt %, refer to the Data List (Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015] ).

Result: 

NG 

REPLACE ACCELERATOR PEDAL POSITION SENSOR ASSEMBLY 

(Refer to REMOVAL [09/2014 - 10/2015] )

Result: 

OK 

See step  6

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Start the engine.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / Vehicle Speed.
5. Read the value displayed on the Techstream.

   Standard

   Techstream Display	Condition	Specified Condition
   Vehicle Speed	Vehicle stopped, engine running	0 km/h (0 mph)
   	Vehicle driven at constant speed between 16.1 and 64.4 km/h (10 and 40 mph)	No large fluctuations when driving at a constant speed

   WARNING:

   When performing the confirmation driving pattern, obey all speed limits and traffic laws.

   HINT: 

   Data can be captured relatively easily by using the snapshot function in the Data List. Confirm the data after performing the driving test.

Result: 

NG 

GO TO METER / GAUGE SYSTEM (SPEED SIGNAL CIRCUIT) 

(Refer to Vehicle Speed Signal Circuit [09/2014 - 10/2015] )

Result: 

OK 

See step  7

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Start the engine.
4. Enter the following menus: Chassis / ABS/VSC/TRAC / Data List / FR Wheel Speed, FL Wheel Speed, RR Wheel Speed and RL Wheel Speed.
5. Read the value displayed on the Techstream.

   Standard

   Techstream Display	Condition	Specified Condition
   FR Wheel Speed FL Wheel Speed RR Wheel Speed RL Wheel Speed	Vehicle stopped, engine running	0 km/h (0 mph)
   	Vehicle driven at constant speed between 16.1 and 64.4 km/h (10 and 40 mph)	No large fluctuations when driving at a constant speed

   WARNING:

   When performing the confirmation driving pattern, obey all speed limits and traffic laws.

   HINT: 

   Data can be captured relatively easily by using the snapshot function in the Data List. Confirm the data after performing the driving test.

Result: 

OK
