The pump is supplied with vacuum via the engine intake stroke.</p> <ul class="clsBULLET"> <li>When leak detection is activated, the diaphragm pump pumps the fuel system up to 20 - 30 mbar. The pump diaphragm is then moved out so that the reed contact at the operating rod remains in the "open" position.</li> <li>During the leak diagnosis, the reed contact is monitored to check if it remains open within 10 seconds. This indicates the system is sealed.</li> <li>If the pressure falls (indicating a leak), the diaphragm moves back and the reed contact closes.</li> <li>If the reed contact closes within 10 seconds of leak detection time, a further test is performed: In this case the diaphragm pump pumps four times again. The Engine Control Module (ECM) J623 measures the time for each of the four pumps until the reed contact is closed again. From that, the control module can recognize a "small leak" (greater than 1 mm in diameter) or a "large leak".</li> </ul> <p>Leak diagnosis is activated automatically shortly following every engine start. If a malfunction is determined, an entry is made to the Diagnostic Trouble Code (DTC) memory.

EVAP System, Leak Detection

Function

The leak detection system recognizes leaks in the complete fuel system, including the fuel tank, EVAP canister and the Evaporative Emission (EVAP) Canister Purge Regulator Valve N80.

On the mechanical side, the leak detection system consists mainly of a vacuum-driven diaphragm pump equipped with a reed contact on the actuation rod of the pump diaphragm. The pump is supplied with vacuum via the engine intake stroke.

  • When leak detection is activated, the diaphragm pump pumps the fuel system up to 20 - 30 mbar. The pump diaphragm is then moved out so that the reed contact at the operating rod remains in the "open" position.
  • During the leak diagnosis, the reed contact is monitored to check if it remains open within 10 seconds. This indicates the system is sealed.
  • If the pressure falls (indicating a leak), the diaphragm moves back and the reed contact closes.
  • If the reed contact closes within 10 seconds of leak detection time, a further test is performed: In this case the diaphragm pump pumps four times again. The Engine Control Module (ECM) J623 measures the time for each of the four pumps until the reed contact is closed again. From that, the control module can recognize a "small leak" (greater than 1 mm in diameter) or a "large leak".

Leak diagnosis is activated automatically shortly following every engine start. If a malfunction is determined, an entry is made to the Diagnostic Trouble Code (DTC) memory. The Malfunction Indicator Lamp (MIL) K83 in the instrument cluster lights up if the malfunction is recognized for two subsequent starts.

EVAP System, Checking for Leaks

Special tools, testers and auxiliary items required

  • Smoke tester.
  • EVAP and Fuel Supply System Vacuum hose and line routing diagram.

NOTE:
  • Secure all hose connections using hose clamps appropriate for the model type .
  • Replace seals and gaskets when performing repair work.

Leak checking

  • Using a Smoke tester , check the Evaporative Emission (EVAP) canister system for leaks.

NOTE:
  • Always follow the manufacturers directions for the proper installation and operation of the Smoke tester being used.

If a leak is found:

  • Check the fuel filler cap seal for damage and for proper installation. Replace if necessary.
  • Check the seals under the locking flanges and the union nuts are properly tightened on the fuel tank.
  • Check all hose connections of the fuel supply system and replace or repair any leaking lines.
  • Check all hose connections of the EVAP system and replace or repair any leaking lines.
  • Repair or replace any damaged component.

If no leaks are found in the EVAP and Fuel Supply System:

If a DTC was set and does not return:

Repair complete, Generate readiness code. Refer to --> Readiness Code.

  • End diagnosis.

If the DTC returns and no leaks are found in the EVAP and Fuel Supply System:

  • Check the DTC memory for any DTC codes pertaining to the EVAP and Fuel Supply Systems. If a DTC is stored, perform the diagnostic test procedure for the suspected component. Refer to --> Diagnostic Mode 03: Interrogating Fault Memory.

Safety Precautions

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system. Note the following:

CAUTION: The fuel system is under high pressure! Before opening high pressure components of the fuel injection system, pressure must be relieved to residual pressure. Wrap a clean rag around the connection and relieve residual pressure by carefully loosening the connection.

  • Always switch off ignition before disconnecting or connecting lines of the fuel injection and ignition system, including test leads.
  • During some of the tests, a Diagnostic Trouble Code (DTC) may be recognized and stored by the control module. At the end of all tests and repairs, the DTC memory should be checked and, if necessary, erased. After erasing the DTC memory, a readiness code must be generated.
  • Always switch the ignition off before cleaning engine.

CAUTION:
  • The battery must only be disconnected and connected with the ignition switched off, since the Engine Control Module (ECM) J623 can otherwise be damaged.
  • Observe procedures for disconnecting the battery --> .

Observe the following if test and measuring instruments are required during a test drive:

CAUTION:
  • Test and measuring equipment must always be secured to the rear seat and be operated from there by a second person.
  • If test and measuring instruments are operated from the front passengers seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is deployed.

Rules for Cleanliness

Even minor contaminations can lead to malfunctions in the fuel injection system. When working on the fuel supply/injection system, pay careful attention to the following rules for cleanliness:

  • Thoroughly clean all unions and adjacent areas with engine or brake cleaner and dry before disconnecting.
  • Plug open lines and connections immediately with appropriate protective caps.
  • Place removed parts on a clean surface and cover. Use lint-free cloths.
  • Install clean components: Remove replacement parts immediately prior to installation. Do not use parts that have been stored unpackaged (e.g. in tool boxes etc.).
  • When the system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.
  • Separated electrical connectors: Protect from dirt and moisture. Make sure connections are dry when reconnecting.

Generic Scan Tool Manual Contents

GST is an acronym for Generic Scan Tool Manual.

Included in the contents of this GST manual is a summary table of the vehicle specific OBD II Emission Related Engine and Transmission DTCs. This table contains all necessary Malfunction Criteria, Threshold Values, Secondary Parameters, Enabling Conditions, Monitoring Time Length, Frequency of Checks, and MIL Illumination to accurately monitor and diagnose the Engine Emissions and Transmission and perform all functions required to run Modes 01 through 09 with a hand held scan tool. For a further description of the monitor strategies, a document reference has been provided throughout this GST manual to the applicable OBD System Strategy document.

This GST manual also contains the step by step pin point test procedures to accurately diagnose the suspected component or system once a DTC has been set. All references to repair procedures and wiring diagrams will be found within the diagnostic test procedure.

OBD Systems

OBD II

OBD is an acronym for the On Board Diagnostic System.

California OBD II applies to all gasoline engine vehicles up to 14,000 lbs. Gross Vehicle Weight Rating (GVWR) starting in the 1996 MY and all diesel engine vehicles up to 14,000 lbs. GVWR starting in the 1997 MY.

Several states in the Northeastern United States have chosen to adopt the California emission regulations starting in the 1998 MY and are known as "Green States".

Green States receive California-certified vehicles for passenger cars and light trucks up to 6,000 lbs. GVWR. Starting in the 2004 MY, Federal vehicle over 8,500 lbs. will start phasing in OBD II.

Starting in 2004 MY, gasoline-fueled Medium Duty Passenger Vehicles (MDPVs) are required to have OBD II. Federal OBD II applies to all gasoline engine vehicles up to 8,500 lbs. GVWR starting in the 1996 MY and all diesel engine vehicles up to 8,500 lbs. GVWR starting in the 1997 MY.

OBD II system implementation and operation is described in the remainder of this document.

Malfunction Indicator Lamp Illumination

MIL is an acronym for the Malfunction Indicator Lamp.

If the ECM recognizes a malfunction that leads to increased emissions values, it indicates them by lighting the MIL which is located in the instrument cluster.

The ECM switches on the MIL after the ignition is switched on. Shortly after the engine is started, The MIL goes out if the ECM does not detect a malfunction that increases the emissions values.

If the ECM recognizes a malfunction that leads to increased emissions during the operation of the engine, the ECM switches on the MIL and an entry is stored in the DTC memory of the ECM.

CAN Data Link

CAN is an acronym for Controller Area Network.

The ECM communicates with all databus capable control modules by a CAN Data Link.

The databus capable control modules (i.e. Engine Coolant temperature Sensor) are connected by two data bus wires which are twisted together (CAN_High and CAN_Low), and exchange information (messages) to the ECM. Missing information on the databus is then recognized and stored as a malfunction.

The ECM illuminates the MIL through the CAN data link and tells the MIL to turn on, turn off, or blink.

Electronic Power Control Warning Lamp

EPC is an acronym that stands for the Electronic Power Control (E-gas).

The ECM monitors all EPC components after the ignition is switched on.

If a malfunction is recognized in the EPC system during the operation of the engine, the ECM switches on the EPC which is located in the instrument cluster and an entry is stored in the DTC memory of the ECM.

General Diagnosis

General Diagnosis

The following table provides quick links to all chapters in this section.

Preliminary Check

Before performing any pin point test or component diagnosis, a preliminary check must be performed.

Check the Technical Bulletins for information that may supersede any information included in this article.

  • Connect the scan tool.
  • Switch the ignition on.
  • Using the scan tool, check for any stored or related DTCs.

If other DTCs are stored:

  • Repair these DTCs first before performing the following procedure.

If no other DTCs are stored:

If the DTC returns:

  • Perform the diagnostic procedure.

If the DTC does not return:

  • The fault is intermittent or a sporadic condition may exist.
  • Check the suspected component, electrical harness and electrical harness connectors for damage, corrosion, loose or broken terminals.
  • If necessary, repair the faulty wiring connection.
  • Perform a road test to verify the repair.

If the DTC returns:

  • Perform the diagnostic procedure.

If the DTC does not return:

The fault may have been the result of a loose electrical connection.

  • Generate readiness code. Refer to --> Readiness Code.
  • End of diagnosis.

Readiness Code

Readiness Code

Readiness Code Description

Diagnostics are performed at regular intervals during normal vehicle operation. After repairing an emissions related system, a readiness code is generated by road testing the vehicle.

If a malfunction is recognized during the drive cycle, it will be stored in the DTC memory.

The OBD drive cycle operation will be monitored with a hand held diagnostic tool. Consult the manufacturers instruction manual for correct tool operation.

The readiness code is erased every time the DTC memory is erased or any time the battery is disconnected. If the DTC memory has been erased or the battery is disconnected, a new readiness code must be generated.

Only erase the DTC memory if a DTC has been stored.

General Recommendations

Most monitors will complete easier and quicker using a steady-foot and smooth acceleration during the drive cycle operation, cruise, and acceleration modes.

Operating Conditions

For the EVAP monitor test, the coolant temperature and the ambient air temperature must be between 10°C and 35°C with a difference between them no greater than 4°C. The ambient air temperature must not change more than 4°C during the drive cycle procedure (e.g. when driving out of a heated workshop in the winter).

Test requirements

  • Erase the DTC memory.
  • Coolant temperature must be between 80°C and 110°C.
  • The Intake Air Temperature (IAT) must be between 10°C and 35°C.
  • Battery voltage must be a minimum of 12.5 volts.
  • Fuel tank level 1/4 to 3/4 full.

CAUTION: When performing the drive cycle operation, pay strict attention to driving conditions and please observe and obey all posted speed limits. Failure to follow these instructions may result in personal injury or possible death.

Drive Cycle Procedure

  • Connect the diagnostic tester.
  • Switch the ignition on and start the vehicle.
  • Idle the vehicle for 2-3 minutes. This executes the O2S Heater, Misfire, Secondary AIR, Fuel Trim, and Purge system monitors.
  • Drive the vehicle at 45-55 mph for a continuous 7-minute period, avoid stopping. This executes the EVAP, O2S, Fuel Trim, and Misfire monitors.
  • Accelerate the vehicle to an engine speed of 5000 RPM (with automatic transmission use the tip-tronic mode); lift off the throttle until the engine speed is around 1200 rpm. This executes the fuel cut off
  • Accelerate the vehicle smoothly to 60-65 mph, cruise constantly for 5 min, this executes the Catalyst; O2S, Misfire, Fuel Trim, and Purge System monitors.
  • Decelerate and idle the vehicle again for 3 minutes. This executes the Misfire, Secondary AIR, Fuel Trim, and Purge system monitors.
  • Check the status of the readiness code.

NOTE:
  • Depending on the diagnostic tester used. The readiness code status may be displayed as complete, passed or OK.

  • If any engine monitor fails the drive cycle test. Repeat the drive cycle test until all engine monitors have successfully run through and passed.

NOTE:
  • When repeating the drive cycle operation for a failed EVAP monitor or thermostat-monitor, allow the engine to cool until the coolant temperature and the ambient air temperature are be between 10°C and 35°C with a difference between them no greater than 4°C is observed and repeat the drive cycle operation.

If the drive cycle operation fails again.

  • Check the DTC memory for stored DTCs.

Repair the vehicle if necessary.

  • Repeat the drive cycle operation until all engine monitors have successfully run through and passed.
  • Remove the diagnostic tester and switch the ignition off.
  • End of operation.
