   4. Install the stop light switch assembly.

      Refer to INSTALLATION [02/2014 - ]

1. Inspect the brake pedal stroke sensor assembly.
   1. Connect the Techstream to the DLC3 with the power switch off.
   2. Turn the power switch on (IG).
   3. Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Data List / Stroke Sensor.

      Chassis > ABS/VSC/TRAC > Data List

   *a	Brake Pedal Free Play

   Brake Pedal Free Play

   1.0 to 2.0 mm (0.0394 to 0.0787 in.)

   If the brake pedal free play is not as specified, check the stop light switch clearance.

   Refer to INSTALLATION [02/2014 - ]

   If the brake pedal free play is as specified, proceed to the Inspect Brake Pedal Reserve Distance procedure.

1. Release the parking brake.
2. With the power switch on (READY), depress the brake pedal and measure the brake pedal reserve distance as shown in the illustration.
