CHECKING SOFTWARE
Note. For vehicles of model year 2007-2008, the software in the engine control module (ECM) should be checked before fault tracing is carried out of the fault relating to the leak from the tank system.
Scheme 388
Scheme 389
- Ignition on. Use the VCT2000 (or appropriate scan tool) to read out and check the software version in the Engine control module. NOTE: More instructions follow together with the read out.
Has the latest software been downloaded to the control module?
- YES Refer to «PERFORM QUICK-TEST TANK SYSTEM»(ref-476782-S11973385782012060500000)
Scheme 390
- Activate the test using the VCT2000 (or appropriate scan tool).
- Read off initial parameters and check them according to start conditions for performing the test.
- Check that the test has started. Parameters run status shall go to "In progress" and the test phase shall go to "Reference". NOTE: If the test does not start, check that the start conditions are fulfilled. When the reference phase is finished, check of the tank system starts. The pressure in the tank starts to increase, see graph. Within 15 minutes the Engine control module makes a decision as to whether there is leakage in the tank system or not. The test is finished.
- Check parameters for test result and follow relevant instructions provided in this service information. NOTE: Estimated leakage shall be used to get an idea of the proximity to the diagnostic trouble code limit. If the estimated leakage is very near the diagnostic trouble code limit (greater than 0.3mm), troubleshooting should probably be performed despite the Tank system, test result shows "No leakage found", especially if a diagnostic trouble code for leakage has been stored earlier. NOTE: Use diagnostic trouble code counter to, see the frequency of the problem. Also use frozen values to get an idea if external conditions may have affected the result. Compare with current conditions in the workshop. Conditions for starting the quick test of the fuel tank system No DTCs related to EVAP purge valve or ambient air pressure sensor set. Battery voltage 11-15 V. Atmospheric pressure higher than 750 hPa, approx. 2500 m (8200 ft). Fuel level 0-85 %. Ambient air temperature 4-35 °C. NOTE: The battery voltage must be correct throughout the entire test. The test can take up to 15 minutes, depending on the quantity of fuel in the fuel tank. It is highly recommended to use the constant voltage charger, Midtronics PSC-550, during the test. For more information, see 30-04 (USA/CDN).

CHECKING COMPONENT AND CONNECTIONS
- By activating quick-test of EVAP-valve, the valve's status can be decided. The test is based on pressure pulses through the valve and, in this way, the valve's function can be checked. If malfunction is detected on the EVAP-valve when performing the quick-test, this indicates that the malfunction is permanent.
- Engine idling during the entire test. Activate quick-test EVAP-valve. The test takes a few seconds. If the result shows "Malfunction found", function is poor. Check hose/hose connections between EVAP-valve and canister for damage, clogging or squeezing. The valve may need to be cleaned or replaced. If the result shows "No malfunction found", function is correct. Then check hose/hose connections between EVAP-valve and inlet pipe for damage, clogging or squeezing. Remedy as necessary.

HINT: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the connectors, components, etc.
- Run the starter motor/start the engine.
- Read off the status from the ignition lock. Check that the read off status from the ignition lock corresponds to the actual position of the ignition lock.
Is the function OK?
- YES VERIFIED: Troubleshooting has been completed.
- NO Refer to «INFORMATION»(ref-476782-S08082117472012060500000)
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
- Ignition on, wait for at least 15 seconds to perform the diagnosis. Read the diagnostic status and fault status for the diagnostic trouble code by selecting the diagnostic trouble code in the list. Check if the malfunction is permanent or intermittent by reading off the diagnostic trouble code's status when the diagnostic status is "Implemented". If the trouble status is "Malfunction found", this indicates that the malfunction is permanent. If the trouble status is "No malfunction found", this indicates that the malfunction is intermittent and not active right now. NOTE: Trouble status cannot go from "Malfunction found" to "No malfunction found" in the same operating cycle.

REPLACING THE COMPONENT
The engine control module (ECM) has registered an internal fault.
If the fault is intermittent, it has been registered previously but no longer remains. Intermittent faults can be due to disruption when the engine control module (ECM) started or can be another type of fault that may recur at different instances. The fault is assessed on a case by case basis. If the fault recurs, replace the engine control module (ECM).
In the event of a permanent fault, replace the engine control module (ECM).
Remedy as necessary.

The engine control module (ECM) has registered an internal fault.
If the fault is intermittent, it has been registered previously but no longer remains. Intermittent faults can be due to disruption when the engine control module (ECM) started or can be another type of fault that may recur at different instances. The fault is assessed on a case by case basis. If the fault recurs, replace the engine control module (ECM).
In the event of a permanent fault, replace the engine control module (ECM).
Remedy as necessary.
