Brake Override System: Procedure
- CHECK DTC OUTPUT
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Enter the following menus: System Select / Health Check.
- Check DTCs.RESULT
Result Proceed to DTC is not output A DTCs are output B
B → See step 11
A: Go to next step
- READ VALUE USING TECHSTREAM (STOP LIGHT SWITCH AND and ST1)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / Stop Light Switch and ST1.
- 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
NG → See step 10
OK: Go to next step
- INSPECT BRAKE PEDAL
- Inspect and adjust the brake pedal (for Manual Transmission). Refer to ADJUSTMENT [07/2013 - ] .
- Inspect and adjust the brake pedal (for Automatic Transmission). Refer to ADJUSTMENT [07/2013 - ]
.
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, so conduct inspection of the brake pedal and stop light switch assembly.

A: Go to next step
- READ VALUE USING TECHSTREAM (ACCELERATOR PEDAL SENSOR)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / Accel Sens. No. 1 Volt % and Accel Sens. No. 2 Volt %.
- Read the value displayed on the Techstream.
OK
Techstream Display Condition Specified Condition Accel Sens. No. 1 Volt % Accelerator Pedal
Released → Depressed → ReleasedValues 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 [07/2013 - ] .
NG → See step 8
OK: Go to next step
- READ VALUE USING TECHSTREAM (VEHICLE SPEED)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Start the engine.
- Enter the following menus: Powertrain / Engine / Data List / Vehicle Speed.
- 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 running at constant speed between 16.1 to 64.4 km/h (10 to 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 drive test.
NG → See step 7
OK: Go to next step
- READ VALUE USING TECHSTREAM (FR, FL, RR, RL WHEEL SPEED)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Start the engine.
- Enter the following menus: Chassis / ABS/VSC/TRAC / Data List / FR Wheel Speed, FL Wheel Speed, RR Wheel Speed and RL Wheel Speed.
- Read the value displayed on the Techstream.
Standard
Techstream Display Condition Specified Condition FR Wheel Speed
FL Wheel Speed
RR Wheel Speed
RL Wheel SpeedVehicle stopped, engine running 0 km/h (0 mph) Vehicle running at constant speed between 16.1 to 64.4 km/h (10 to 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 drive test.
NG → INSPECT FRONT OR REAR SPEED SENSOR
OK → END
