FAULT-TRACING INFORMATION

Fault-tracing is not followed by verification for this fault.

HINT: After the diagnostic trouble codes (DTCs) are erased, the function of the leak diagnostic unit can be checked by running a quick test of the fuel tank system in the vehicle communication socket. If there is a fault, the fault status will be "FAULT FOUND" on the leak diagnostic unit.

The information can be displayed again or fault-tracing this fault can be interrupted.

CHECKING THE STATUS

  1. Ignition on. Activate the valve in the leak diagnostic unit. Check if the fault is permanent or intermittent. The valve clicks when it is activated. The fault is permanent if the valve does not activate. If the valve is activated, this is an indication that the fault was present previously but that it is not active at the moment, intermittent fault.

  1. Use the VCT2000 (or appropriate scan tool) to activate the test.
  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 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: In the event of a the results from the estimated leakage must be entered in 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.

FUEL TANK SYSTEM, CHECK

Note. This instruction is deliberately written for use with different types of leak detecting equipment. Therefore certain components may differ on different equipment.

SAFETY

First read, see SAFETY REGULATIONS FOR HANDLING FUEL .

Note. Follow the safety precautions for the equipment. Follow the instructions for connecting, disconnecting, use and maintenance.

HINT: Be aware of the risks of igniting the fuel. Do not let the temperature of the tank fall below 0 °C when carrying out checks.

CAUTIONNever leave the car unattended with the tank system pressurized

PREPARATION

Ignition off.

Seal the intake air hose for the carbon filter container. (A rubber plug is sufficient on certain models.)

Expose the evaporative emission system (EVAP) valve.

Disconnect the hose (1) between the carbon filter container and the evaporative emission system (EVAP) valve.

DETERMINE THE SIZE OF THE LEAK

Calibrate the equipment in relation to the definition of a major or minor leak for the relevant vehicle. See the instructions provided by the equipment supplier.

Connect the leak detecting equipment hose for gas to the detached hose.

Pressurize the fuel tank system. Check the result against the default value to determine the size of the leak.

HINT: The supplier's instructions often contain useful tips to facilitate carrying out checks.

Complete pressurization.

LOCATING LEAKAGE

Connect the leak detecting equipment hose for smoke to the detached hose.

Fill the tank system with smoke. The time taken to fill the system depends on the size and volume of the system, and the performance of the equipment.

Visually check the evaporative emission (EVAP) system, using a halogen and / or UV lamp.

HINT: The supplier's instructions often contain useful tips to facilitate leak tracing.

Stop filling with smoke.

RESETTING

Reinstall the hose between the carbon filter container and evaporative emission system (EVAP) valve.

Install the evaporative emission system (EVAP) valve.

Remove the seal at the intake air hose for the carbon filter container.

INFORMATION

No fault-tracing has been developed for this diagnostic trouble code (DTC). A diagnostic trouble code for CAN communication can also be generated in the Central Electronic Module (CEM). This diagnostic trouble code shall not be cleared until the trouble code in the central electronic module (CEM) and in other affected control modules has been remedied and cleared. Therefore, first read the diagnostic trouble codes in the Central Electronic Module (CEM) and other affected control modules, perform fault tracing and remedy as necessary. This diagnostic trouble code (DTC) can then be erased. For further information on this diagnostic trouble code, see Diagnostic trouble code (DTC) information.

The engine control module (ECM) receives information on vehicle speed from the transmission control module (TCM) via the CAN network. The diagnostic trouble code is generated when the signal on gear selector position has a reliability that is too low (quality factor too low).

This could be due to a fault in the transmission control module (TCM) or intermittent faults in the CAN network.

Check and remedy any diagnostic trouble codes in the transmission control module (TCM).

Check the diagnostic trouble codes in the central electronic module (CEM) for CAN network faults.

CHECKING THE COMPONENT

Check the turbocharger (TC) control valve by activating it. The turbocharger (TC) control valve must click when it is activated.

HINT: The operation of the turbocharger (TC) control valve can be intermittent. A damaged turbocharger (TC) control valve can be difficult to detect during activation.

Check the setting of the pressure servo for the boost pressure control (BPC) valve. Check that the pressure servo for the boost pressure control (BPC) valve is functioning correctly.

Check the operation of the boost pressure control (BPC) valve. Check that the boost pressure control (BPC) valve is not sticking.

Remedy as necessary.

HINT: After carrying out the repair, check that the fault has been remedied.

  1. Ignition off
  2. Reconnect the connectors, reinstall components etc.
  3. Test drive the vehicle on the road. Ensure that high boost pressure is reached (high load) so that the engine control module (ECM) can run the diagnostic.
  4. Connect VCT2000 (or appropriate scan tool) to the data link connector (DLC) without switching off the engine. NOTE: If the engine is switched off, the stored fault status will be erased and the test drive will have to be repeated. Read off the diagnostic status and fault status for the diagnostic trouble code (DTC) by selecting the relevant diagnostic trouble code (DTC) from the list. Check the fault status for the diagnostic trouble code (DTC) when the diagnostic is "Complete". If the diagnostic is not complete after the test drive, further test driving is required. If the function is correct, the fault status must be "No fault found" when the diagnostic is complete.
