PREPARATORY CHECKS

Check and note which adaption area for bank 1 is faulty by going through the list of adaption areas.

The adaptation value is considered outside normal range if it is lower than 0.85 (engine runs rich) or higher than 1.15 (engine runs lean).

HINT: The ranges consist of a table where the first digit in the name designates RPM range and the second load range.

HINT: Thus, range 1.1 designates a case with low RPM with low load, and 6.6 a case with high RPM and high load.

1. Continue Refer to «CHECKING SYSTEM»(ref-476781-S04575346742012060500000)

Scheme 356

HINT: If the fuel adaptations indicate too lean fuel/air mixture (adaptation value above 1.0) at idle, this indicates an air leak.

HINT: To find the problem, proceed as follows

1. Check the inlet system and exhaust system for leaks.
2. Engine running.
3. Check fuel pressure to, see if it is low.
4. Ignition on
5. Check residual pressure for too low residual pressure.

Remedy as necessary.

HINT: Normal fuel pressure at idle and warm engine shall be approx. 480 kPa.

HINT: The residual pressure when the engine is off and the ignition is on shall be approx. 100 kPa lower than during idle.

1. Continue Refer to «CHECKING MASS AIR FLOW SENSOR»(ref-476781-S28363986482012060500000)

CHECKING MASS AIR FLOW SENSOR

1. Engine running. Check and compare the calculated air mass with the actual air mass readout from the mass air flow sensor. Try by measuring at different RPM. HINT: Differences of more than approx. 20% between the signals indicate a malfunction of the mass air flow sensor. HINT: Remedy as necessary. NOTE: When replacing mass air flow sensor, repeat the check to verify that the problem has been solved with the replacement.

1. For more information about current fuel compensation, refer to «READOUT OF TOTAL FUEL COMPENSATION»(ref-476781-S42396714772012060500000) .
2. To continue, refer to «RESET ADAPTATIONS»(ref-476781-S07864107602012060500000)

READOUT OF TOTAL FUEL COMPENSATION

1. Engine running.
2. For reading out total fuel compensation at every given moment, use the VCT2000 (or appropriate scan tool). HINT: The readout value shows the short-term fuel trim's and the long-term fuel trim's total compensation of the injection time in real time. HINT: Positive values indicate additional fuel, negative values indicate reduction of additional fuel. Try by measuring at different RPM with different engine load. NOTE: Keep in mind that the EVAP-valve's addition of fuel vapors affect the readout. For example, squeeze the hose between the EVAP-valve and inlet pipe to minimize addition of fuel from the EVAP-system.

1. Continue Refer to «RESET ADAPTATIONS»(ref-476781-S07864107602012060500000)

START ADAPTATIONS

Test-drive the vehicle on road and drive a little in different operating situations for 20 minutes, in order to complete as many adaptations as possible.

Check and note if any adaptation range is still incorrect by scrolling through the list with adaptation ranges.

The adaptation value is considered outside normal range if it is lower than 0.85 or higher than 1.15.

HINT: Also, perform a few full throttle accelerations to perform the adaptations that are not affected by normal driving.

For adaptation to start, certain conditions must be fulfilled

1. Engine speed > or = 600 RPM.
2. Engine temperature between 80-110°C.
3. Adaptation active = executed.
4. EVAP-valve not active = 0 μs.

HINT: At high fuel vaporization the EVAP-valve is active longer time and then it may be necessary to disconnect the hose between the EVAP-valve and the canister.

Are these values OK?

1. YES OKAY: Troubleshooting has been completed.
2. NO Refer to «INFORMATION»(ref-476781-S08480115482012060500000)

CHECKING ETHANOL CONTENT

HINT: The cause of the symptom and/or diagnostic trouble code may be that the vehicle has been refuelled with incorrect fuel for that vehicle. The fuel system contains fuel with too high ethanol content.

The energy content in ethanol-diluted fuel is lower than in pure gasoline. This means that the control module compensates for the lower energy content, by increasing the injection volume, to be able to reach lambda=1 at the front heated oxygen sensor. This compensation is normally called "Front lambda control slow" or "Lambda integrator", and varies to compensate for the vehicle's status in the form of component spread, small air leaks, wear, etc. The value of this compensation in the ideal case is 1.0 for pure gasoline. Increased ethanol content of the fuel increases the compensation by approx. 0.05 per 10% ethanol dilution.

The control module is designed to handle an ethanol dilution up to 25%. In combination with other deviations from the ideal case, however, lower ethanol content may be enough to cause customer symptoms. This mainly occurs at engine start with cool engine at outdoor temperatures below 0 °C. Then the diagnostic trouble code may also be set for the engine running on too lean mixture.

Note. In a vehicle intended for gasoline, only pure gasoline shall be used. Even if engine start/operation works, other fuel-related components in the vehicle may be damaged by too high ethanol content.

1. Measure the ethanol content of the fuel according to the instructions below. If measured ethanol content is above 25%, then ethanol dilution is the likely cause of the symptom and/or to the diagnostic trouble code being stored. If measured ethanol content is below 25%, symptoms and/or diagnostic trouble code may have been caused by earlier occurrence of incorrect fuel in the system for that vehicle. HINT: Check refuelling history by talking to customer. If nothing indicates incorrect fuel, neither now nor earlier, continue troubleshooting to check other possible causes of faults.

CHECKING SYSTEM

1. Check the air filter. Check for blockage.

HINT: If the fuel adaptations indicate too rich fuel/air mixture (adaptation value below 1.0) in several adaptation ranges, this indicates a fuel malfunction, e. g., too high fuel pressure.

HINT: To find the problem, proceed as follows

1. Check that the engine's oil level is not too high. HINT: The adaptations may show rich if several cold starts have been performed with short subsequent driving time, e. g., moving of vehicles, and the engine oil has thus been contaminated by gasoline. This affect on the adaptations disappears after a period of driving due to combustion of the fuel vapors by the engine. Check the EVAP-valve for leakage. HINT: A valve that does not seal constantly leaks fuel vapors, which thus affect the adaptations.
2. Engine running.
3. Check fuel pressure for high fuel pressure.
4. Ignition on
5. Check residual pressure for too low residual pressure.

Remedy as necessary.

HINT: Normal fuel pressure at idle and warm engine shall be approx. 480 kPa.

HINT: The residual pressure when the engine is off and the ignition is on shall be approx. 100 kPa lower than during idle.

HINT: If the residual pressure is too low, one malfunction cause may be leaking (non-sealing) injectors, for example.

1. Continue Refer to «CHECKING MASS AIR FLOW SENSOR»(ref-476781-S24790436842012060500000)

1. Engine running. Check and compare the calculated air mass with the actual air mass readout from the mass air flow sensor. Try by measuring at different RPM. HINT: Differences of more than approx. 20% between the signals indicate a malfunction of the mass air flow sensor. HINT: Remedy as necessary. NOTE: When replacing mass air flow sensor, repeat the check to verify that the problem has been solved with the replacement.

HINT: The readout value shows the short-term fuel trim's and the long-term fuel trim's total compensation of the injection time in real time. HINT: Positive values indicate additional fuel, negative values indicate reduction of additional fuel. Try by measuring at different RPM with different engine load. NOTE: Keep in mind that the EVAP-valve's addition of fuel vapors affect the readout. For example, squeeze the hose between the EVAP-valve and inlet pipe to minimize addition of fuel from the EVAP-system.

Check and note if any adaptation range is still incorrect by scrolling through the list with adaptation ranges.

The adaptation value is considered outside normal range if it is lower than 0.85 or higher than 1.15.

HINT: Also, perform a few full throttle accelerations to perform the adaptations that are not affected by normal driving.

For adaptation to start, certain conditions must be fulfilled

1. Engine speed > or = 600 RPM.
2. Engine temperature between 80-110°C.

HINT: The cause of the symptom and/or diagnostic trouble code may be that the vehicle has been refuelled with incorrect fuel for that vehicle. The fuel system contains fuel with too high ethanol content.

The energy content in ethanol-diluted fuel is lower than in pure gasoline. This means that the control module compensates for the lower energy content, by increasing the injection volume, to be able to reach lambda=1 at the front heated oxygen sensor. This compensation is normally called "Front lambda control slow" or "Lambda integrator", and varies to compensate for the vehicle's status in the form of component spread, small air leaks, wear, etc. The value of this compensation in the ideal case is 1.0 for pure gasoline. Increased ethanol content of the fuel increases the compensation by approx. 0.05 per 10% ethanol dilution.

The control module is designed to handle an ethanol dilution up to 25%. In combination with other deviations from the ideal case, however, lower ethanol content may be enough to cause customer symptoms. This mainly occurs at engine start with cool engine at outdoor temperatures below 0 °C. Then the diagnostic trouble code may also be set for the engine running on too lean mixture.

Note. In a vehicle intended for gasoline, only pure gasoline shall be used. Even if engine start/operation works, other fuel-related components in the vehicle may be damaged by too high ethanol content.

2. For reading out total fuel compensation at every given moment, use the VCT2000 (or appropriate scan tool). HINT: The readout value shows the short-term fuel trim's and the long-term fuel trim's total compensation of the injection time in real time. HINT: Positive values indicate additional fuel, negative values indicate reduction of additional fuel. Try by measuring at different RPM with different engine load. NOTE: Keep in mind that the EVAP-valve's addition of fuel vapors affect the readout. For example, squeeze the hose between the EVAP-valve and inlet pipe to minimize addition of fuel from the EVAP-system.

1. Continue Refer to «RESET ADAPTATIONS»(ref-476781-S20195854402012060500000)

Test-drive the vehicle on road and drive a little in different operating situations for 20 minutes, in order to complete as many adaptations as possible.

Check and note if any adaptation range is still incorrect by scrolling through the list with adaptation ranges.

The adaptation value is considered outside normal range if it is lower than 0.85 or higher than 1.15.

HINT: Also, perform a few full throttle accelerations to perform the adaptations that are not affected by normal driving.

For adaptation to start, certain conditions must be fulfilled

1. Engine speed > or = 600 RPM.
2. Engine temperature between 80-110°C.
3. Adaptation active = executed.
4. EVAP-valve not active = 0 μs.

HINT: At high fuel vaporization the EVAP-valve is active longer time and then it may be necessary to disconnect the hose between the EVAP-valve and the canister.

Are these values OK?

1. YES OKAY: Troubleshooting has been completed.
2. NO Refer to «INFORMATION»(ref-476781-S34250939462012060500000)

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

1. Ignition off
2. Reconnect the connectors, components, etc.
3. Start the engine.
4. Test drive the car on the road in different driving conditions with high and low loads so that the engine control module (ECM) can carry out diagnostics.
5. Connect VCT2000 (or appropriate scan tool) to the data link connector without switching off the engine.
6. Read the diagnostic status and fault status for the diagnostic trouble code by selecting the diagnostic trouble code in the list. NOTE: If the engine is switched off, the stored fault status will be erased and the test drive will have to be repeated. Check the fault status for the diagnostic trouble code when the scan is "Implemented". When the function is correct the fault status should be "No fault found" when the scan is implemented.

1. Start the engine. Read the diagnostic status and fault status for the diagnostic trouble code by selecting the diagnostic trouble code in the list. Increase the engine speed a few times until the diagnosis is "Completed". Check whether the fault is permanent or intermittent by reading the fault status of the trouble code when the diagnostic status is "Completed". If the fault status is "Fault found", the fault is permanent. If the fault status is "No fault found", the fault is intermittent and not currently active. NOTE: The fault status cannot switch from "Fault found" to "No fault found" within the same operating cycle.
