  Standard Voltage

  Tester Connection	Condition	Specified Condition	Result
  C42-3(VC) - C42-2(E2)	Ignition switch ON	4.5 to 5.5 V	V
  C42-1(PTA) - C42-2(E2)	Ignition switch ON	3.0 to 5.5 V	V

  If the result is not as specified, repair or replace the wire harness or connector.

• Check the turbo pressure.
  1. Turn the ignition switch to ON.
  2. According to the display on the GTS read the Data List.

     OK

     The value is approximately equal to atmospheric pressure.

     HINT: 

     • Standard atmospheric pressure is approximately 101 kPa (abs) (15 psi (abs)).
     • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies by weather.
