         Tip:
         

         • It takes approximately 70 seconds to complete the check.

         • The sensors will be checked one by one within the 70 second time period.

         • If the voltage is not within the specified range, troubleshoot the electronically controlled brake system.

         If the result is not as specified, troubleshoot the electronically controlled brake system.

   4. Check the accumulator sensor.

      
      

      1. Move the shift lever to P. Apply the parking brake and connect the GTS to the DLC3.

      2. Turn the power switch on (IG).

      3. Turn the GTS on.

      4. Enter the following menus: Chassis / ABS/VSC/TRC / Data List / Accumulator Sensor.

      5. Depress the brake pedal 4 or 5 times and operate the booster pump motor.

      6. After confirming that the booster pump motor has stopped, check the output voltage.

         Standard Voltage
         2.6 to 3.8 V

         If the result is not as specified, troubleshoot the electronically controlled brake system.
