SPECIAL EDITION
2012-Current Model Subaru Evaporative Diagnostics & Smoke Testing
When faced with an Evaporative Emissions DTC (P0441-P0459, P2404 etc.), the first thing most Technicians do is reach for the smoke machine to check for leaks.
This should no longer be a Technicians first step for diagnosis.
Never put pressure into the ELCM or use smoke as residual oil in the smoke can contaminate the ELCM and cause internal components to malfunction.
Instead, the first step for diagnosis should be a forced self-test of the evaporative emission system, recording the test results, then graphing the test to determine where the problem is.
Late model Subaru vehicles are equipped with an Electronic Leak Check Module (ELCM) in their evaporative system. The ELCM is a very sensitive and delicate piece of electronic equipment that has the capability of performing self-tests to inspect the systems integrity for leaks and operation. These systems operate on vacuum, not pressure, when performing their self-test.
Follow the outlined directions in this document for performing the ELCM forced self-test, then use the diagnosis procedure found in STIS to identify where the problem is. Technicians can graph the recorded self test and compare it to the diagnosis chart. This chart is in the General Description tab or located at the bottom of most Evap DTC Trouble Trees in STIS. This article also includes a reference chart, along with examples of completed graphs with a set DTC. The Subaru smoke machine tool kit comes with the correct quick disconnect plugs to be able to block off the disconnected lines. Below are step-by-step directions for performing the ELCM force test, saving that test data and using it to diagnose the concern.
NOTE: For diagnosing Evaporative codes on 2011-2014 models, the following testing may not apply. Please see TechTIPS from 3/17 and / or 10/19 for performing this testing.
NOTE: This testing does not work on STI models. Always follow the testing methods outlined in the Service Manual for STI models

- 【Why Need It】For example: 1. The rupture of the vacuum hose will cause the mixture to be too thick, the idle speed will increase, the hot car will not start well, the engine will surge during acceleration, the fuel consumption will increase significantly, and the exhaust pipe will emit black smoke. 2. Blocking will cause the idle speed to drift, and the idle speed is easy to stall. 3. Air leakage in the vacuum tube will cause the engine to run weakly
- 【No Air Pump】Connect shop air supply, connect 12V vehicle power, introduce shop air to the AUTOOL SDT103 fuel leak tester, turn the Flow Dial anti-clockwise to open the air flow, switch on the power at the back of the unit, then AUTOOL SDT103 smoke machine automotive will start to generate smoke.
- 【External Flow Meter】You can easily control the air pressure, because the air pressure of each pipe in the car is different. If the air pressure is too high, the pipe will be damaged, and if the air pressure is too low, the leak will not be detected. Therefore, the flow meter is very important to protect your detection system more effectively. Make testing safer
- 【EVAP Detection】American cars that began production in 1996 are equipped with EVAP service ports; in most American cars, the EVAP service port is usually located in the engine compartment, but the EVAP service port of some special models may be located in other locations. Open the plastic cover of the EVAP service port, then use the spool wrench to remove the check valve clockwise, then install the EVAP service port adapter, and introduce smoke from the port into the EVAP leak detection system.
- 【Wide Testing Range】The smoke leak detector can do smoke testing of multiple systems, such as EVAP systems, Intake Systems, Cooling / EGR /Exhaust Systems, Crankcase Systems, Engine Airtightness, Vacuum Leaks, Low Pressure Turbo leaks.Applicable cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks and speedboats boats.
- 【Multifunction】Our automotive smoke machine can perform various tests such as: EVAP system test, car sealing test, fuel tank system test, exhaust system test, intake system test and various pipe fittings test, ect. It Could be used on all cars, motorcycles, snowmobiles, ATV, light trucks, boats, etc.
- 【Working Principle】 The automotive leak detector tool will change special oil(baby oil or mineral oil) into smoke, then blow smoke into sealed pipe system, you will find leak points in the pipe via the smoke. Please repair the part where leakage exists.
- 【Easy to Use】The automotive smoke tester comes with a hook allows you to hang it on your hood latch. Just add 20ml of baby oil or mineral oil, then connect the detector with the DC12V battery, it can output thick smoke within 20s after turning on, thick smoke output detects even the smallest leaks.
- 【Smart Protection】This smoke tester has overheat & freeze protection, the maximum temperature limit is 90°C, ture on antifreeze protection at a low temperature of -20°C.

The main components in the EVAP system: CPC valve (purge control solenoid) ELCM Canister Fuel tank Drain filter CONTINUED ON THE NEXT PAGE Special Edition TechTIPS Page 2 of 14 OVERVIEW OF EVAPORATIVE SYSTEM (CONTINUED) Solenoid valve for purge control SUMMARY OF EVAP LEAK DIAGNOSIS • EVAP Leak diagnosis is conducted during soak (5~7h after engine stop). • The ELCM draws a vacuum in the Evaporative line and determines the leak by the level of negative pressure. To find a 0.02-inch leak, the ELCM measures two types of pressure: 1) Reference pressure: pressure at the occurrence of a 0.02-inch leak 2) Tank pressure: pressure in the EVAP line While measuring pressures 1) and 2), a P code is established according to the location of the abnormality.

As the test runs, it will perform different phases. Phase Explaination of Phase Phase A The ECM uses this phase to check the operation of the vacuum pump. The ECM simulates a 0.02 leak by using the reference pressure as the vacuum pump is running. The switching valve is in the ‘open’ position. This allows ambient air to enter the ELCM. Phase B The ECM measures the pressure and calculates the limit of negative pressure based on the reference. Phase C The switching valve closes, and ECM measures the evaporative side pressure. The jump in pressure is caused by the movement of the switching valve. This also seals the system from ambient air. Phase D With the switching valve closed, the ECM measures the pressure in the EVAP system in relation to the amount of time it takes to reach maximum vacuum. Phase E The ECM measures the reference pressure again with the 0.02 simulated leak (ELCM orifice). During this phase, the ECM is determining the size of any leaks. Pressure during this phase is compared to pressure during phase B and should be very similar. Special Edition TechTIPS Page 8 of 14 CONTINUED ON THE NEXT PAGE SUMMARY OF EVAP LEAK DIAGNOSIS (CONTINUED) PhaseZ PhaseA PhaseB PhaseB PhaseC PhaseD The test can take 15-30 minutes to complete. Once the test has completed, the SSM will show “No DTC” or “DTC” code is entered.

On turbocharged vehicles, after performing the ELCM self-test, without turning the key off, perform an all DTC scan to verify there are no DTC’s set.
