IM240 Testing at ACE, Melbourne

ABMARC offers IM240 testing at the Automotive Centre of Excellence in Docklands, Melbourne.

ABMARC is Victoria’s only provider of IM240 testing.

The cost of the test is $2,500 inc. GST.

Please email or call 03 9729 5129 to schedule an IM240 test.

IM240 tests are usually run once a month (when sufficient bookings have been made).

Please note that retesting, if required, also costs $2,500. The IM240 test is a short, transient test, developed by the US EPA, which allows high emitting light duty vehicles vehicles to be identified.
The test represents a 3.1 km route with an average speed of 47.3 km/hr and a maximum speed of 91.2 km/hr. The IM240 test certifies compliance with carbon monoxide (CO), carbon dioxide (CO2), total hydrocarbons (THC) and nitrogen oxides (NOx).

The test protocol requires vehicles to be driven on a chassis dynamometer. The vehicle is connected to emissions equipment, and a 240 second drive cycle is driven. Emissions are measured, and you will be provided with a copy of the results writing within 5 business days.

Your VASS engineer will let you know if your vehicle has passed or failed.

Preparing for your IM240 Test

To ensure that your vehicle has the best opportunity to pass the IM240 test, please note the following:

  • The dynamometer and PEMs are sensitive equipment. Vehicles cannot be tested that have fluid leaks of any kind, including exhaust leaks. Any vehicle presenting with leaks, or with evidence of leaks, will not be tested and no refund will be provided. Please check your vehicle thoroughly well in advance of the test day to ensure that it can be put onto the dyne for testing.
  • The drive on the dynamometer for the IM240 test should not be the “first run” for the modified vehicle. It’s not uncommon for minor issues to exist in new modifications, and the IM240 test is not the best place to find them. If significant work has been performed on the engine, we suggest that you take your vehicle to a mechanic that can perform a 5-gas analyser test before booking for the IM240 test. This test typically costs around $90. If your vehicle does not pass the 5-gas analyser test, it will not pass the IM240 test under any circumstances.
  • Ensure that you have driven 150 to 200 kilometers after clearing any engine codes or resetting the ECU. Many vehicles have fuel trims and/or adaptive learning which are not likely to be fully adapted after only a few kilometers of driving. As such, the engine may not have stabilised in an optimised state with respect to emissions, which could cause the vehicle to fail.
  • Ensure that the vehicle is in a good working order and with no malfunction codes.
  • Ensure that all essential fluids are of the correct type and at the correct levels.
  • Ensure that you have sufficient fuel on board for the test. For petrol vehicles, we recommend 98 RON fuel. After your first use of 98 RON fuel, we recommend that you drive you vehicle at high load (for example freeway driving).
  • Make sure that you consider emissions requirements, and not just engine performance, when tuning your engine or having it tuned.
  • Make sure that your catalytic converters are new (or in good condition) and suitable for your vehicle prior to the test.

Vehicle inspection and preparation checklist

Items to be Checked
Engine and Transmission Oil
To maximum level
To maximum level
Brake Fluid
To maximum level
Fuel Tank
Full, with appropriate fuel for the vehicle (we recommend 98 RON for petrol engines)
Tyre Condition
Fluid Leaks
No fluid leaks of any kind from any location including exhaust. No evidence of fluid leaks.
Emissions DTCs
No emissions related DTCs
Exhaust System
No exhaust system leaks, exhaust fitted correctly, no loose connections. Exhaust catalyst in working condition.
Drivetrain in good condition. Wheel bearings, driveshaft, suspension, U-joints and CV boots are not overly worn or deteriorated.
The transmission shifts correctly or the clutch is in good working order.
No faulty sensors prior to test. If your “Check Engine Light” is ON, we may be able to identify the issue through the OBD connector, however, some issues will negatively impact the outcome of the emissions test. It is strongly recommended that you drive the vehicle for at least 100 km after clearing any codes to allow the long term trims to adjust BEFORE presenting your vehicle for an IM240 test.
Air Intake System
Clean filter and no leaks.
Cooling System
Hoses are correctly installed and not showing signs of deterioration. All hose clamps are tight, and radiator fans are working.
Vacuum System
Hoses are correctly installed and not showing signs of deterioration. Ends installed correctly.
Ensure that all wiring is neat and properly grounded.
Mechanical Operation of the Eng
Engine is in good working order, compression is as required, the spark plugs or injectors are in good working order.
Electrical System
The alternator works correctly, the battery is charged and in good condition.
Carry out a catalyst regeneration prior to your test at high speed and high load. (Note that speed limits must still be obeyed when conducting high speed catalyst regeneration).
