For 1990-2009 cars

Depending upon the vehicle make and model, the Service Bay Test is included on the scan tool for some systems. The evaporative emissions (EVAP) Service Bay Test tests the EVAP system, and indicates the failed DTC codes or states that the EVAP system passed. After you complete the repairs, use the EVAP Service Bay Test in order to test the EVAP system. This test takes some time to run.

Important: Failure to meet the necessary requirements may cause inaccurate test results. Before you perform the EVAP Service Bay Test, ensure that the vehicle meets the following requirements.

• | The Powertrain On-Board Diagnostic (OBD) System Check has been performed, ensuring that no DTC has set.

• | The battery voltage is between 9.0 volts and 18.0 volts.

• | The fuel level is 15-85 percent of capacity, or approximately 1/4-3/4 full.

• | The ignition is ON, and the engine coolant temperature (ECT) is 5°C-70°C (40°F-158°F).

• | The IM Ready Flag is not ON.

• | The start-up intake air temperature (IAT) is 4°C-30°C (30°F-86°F).

• | The vehicle speed is less than 3 mph.

• | The throttle angle is less than 2 percent.

• | The BARO is more than 75 kPa.
