Checking software

HINT: For vehicles of model year 2003-2005, the software in engine control module (ECM) should be checked before fault tracing of the fault relating to the leak from the tank system is carried out.

Scheme 434

Scheme 435

1. Ignition on. Click on the VCT2000 symbol to start the read out and check the software version in the Engine Control Module (ECM). NOTE: More instructions follow together with the read out.

Has the latest software been downloaded to the control module?

1. YES Refer to «Perform quick-test tank system»(ref-404047-S35281863172011061000000)
2. NO ANOTHER TEST

Scheme 436

1. Activate the test by pressing on the symbol for VCT2000.
2. Read off initial parameters and check them according to start conditions for performing the test.
3. Press the button "Start" to start the quick-test.
4. 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 (ECM) makes a decision as to whether there is leakage in the tank system or not. The test is finished.
5. Check parameters for test result and follow relevant instructions below. 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, troubleshooting should probably be performed despite the Tank system, test result shows "No leakage found", especially if 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, appr. 2500 m (8200 ft). Fuel level 0-85 %. Ambient air temperature 4-35 °C (39-95 °F). 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).

Reading instructions

Read off the diagnostic trouble codes (DTCs) in the ABS control module and follow the instructions.

Information

No fault tracing has been developed for this diagnostic trouble code.

The diagnostic trouble code for this fault is first generated in the brake control module (BCM) and then in the engine control module (ECM). This diagnostic trouble code cannot be cleared until the code in the brake control module (BCM) has been remedied and cleared.

Thus, first read the diagnostic trouble codes in the brake control module (BCM), perform fault tracing and remedy as necessary. Afterwards, this diagnostic trouble code can be cleared.

HINT: For more information on this diagnostic trouble code, select Information and then Diagnostic trouble code information.

Checking components

Check that the engine speed (RPM) sensor is correctly installed.

Check the engine speed (RPM) sensor connector. Check for intermittent contact resistance and oxidation.

The engine speed (RPM) sensor is sensitive to interference from surrounding power cables, the starter motor cable for example, or similar high amperage cables. This occurs when starting the engine for example.

Interference can cause difficulty in starting the engine, the engine does not start at all, the tachometer flickers at start attempts etc.

Causes of interference can be

1. surrounding power cables, for example an incorrectly routed starter motor cable
2. incorrectly routed transmission bolted joints for the engine.

Checking the power cable

Check for incorrectly routed power cables (routed too close to the engine speed (RPM) sensor).

Checking the bolted joints

When removing and installing the transmission it is important that all the bolts for the engine are correctly tightened. Incorrectly tightened bolts can cause poor ground connection and interfere with the engine speed (RPM) sensor. Check that all the bolts from the transmission to the engine are correctly tightened.

Checking the wiring

Check the signal cable between the engine speed (RPM) sensor terminal #1 and engine control module (ECM) terminal #A48 (#A48) and between the engine speed (RPM) sensor terminal #2 and engine control module (ECM) terminal #A66 (#B6). Check for an intermittent short-circuit to supply voltage. Check for an intermittent short-circuit to ground. Check for an intermittent open-circuit.
