2. Turn the engine switch on (IG) and turn the Techstream on.
3. Enter the following menus: System Select / Health Check.
4. Check DTCs.

   Result

   Result	Proceed to
   No DTC output	A
   DTC output	B

B → See step   11 

A: Go to next step 

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 / 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

NG → See step   10 

OK: Go to next step 

1. Inspect and adjust the brake pedal support assembly. Refer to ADJUSTMENT .

   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 support assembly and stop light switch assembly.

OK: Go to next step 

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 / 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 .

NG → See step   8 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Start the engine.

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 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 

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
