NGS Mach II User Guide v1.1
This test is only available for CAN vehicles.
This test is for checking/diagnosing the vehicle’s Evaporative Emissions Control Systems (EVAP) for
gross leaks.
Note: This test is only for passenger cars and light duty trucks with Controller Area Network (CAN)
technology. Medium duty trucks may fail the test due to the absence of a Fuel Tank Pressure (FTP) sensor.
IMPORTANT!
Before you begin testing the system, be sure the vehicle meets these requirements:
• Fuel level must be between 15-85%. However, for the best results, it is recommended that the fuel
tank is at least half full.
• Fuel temperature should be stabilized and the ambient temperature should be below 90°F. Vapor
pressure and evaporation becomes a factor when the ambient temperature rises above 90°F. This
will affect the test results.
