    Standard Feilkodeavlesning LH2.4

    Fant ikke dette når jeg søkte her. Om det finnes er det jo bare å gi meg smekk og slette tråden.

    Sakser inn fra en annen side



    The
    OBD
    system:

    OBD
    stands for "On Board Diagnostics".

    Many of the LH2.4 cars have a test-socket from which you can read the fault-codes of the
    ECU
    , EZK and TCU. The later model cars (1995-1998 940) has a serial interface instead of a test socket in which the VST-tool or an
    OBDII
    reader is supposed to plug in to read the fault-codes.

    The LH2.4
    ECU
    costantly monitors the following things:

    -The control module's own, internal functions.
    -Heated oxygen sensor (HO2S) and fuel trim.
    -Engine coolant temperature sensor.
    -Mass air flow (
    MAF
    ) sensor.
    -Battery voltage.
    -Throttle position switch (TP switch).
    -Engine speed (RPM) signal from the engine control module (
    ECM
    ).
    -Speedometer signal.
    -Knock enrichment signal from the ignition system (does not apply to B 230 F, B 204 FT/GT).
    -The idle air control (IAC) valve.

    A fault in any of these functions is presented as a diagnostic trouble code (DTC) in diagnostic test mode (DTM) 1.

    The EZK116 constantly monitors the following things:

    -The control module's own, internal functions.
    -Knock sensor (KS) signal.
    -Fuel system load signal.
    -Timing pick-up signal.
    -Temperature sensor signal.
    -Signal from the EGR converter.
    -Signal from the EGR temperature sensor.

    A fault in any of these functions is presented as a diagnostic trouble code (DTC) in test function 1.

    All the diagnostic trouble codes (DTCs) are reversible. This means that if a signal has resulted in a diagnostic trouble code (DTC) being stored and it is OK next time the ignition is turned on, the control module will use the programmed correct value instead of remaining in “limp-home” mode. But the diagnostic trouble code (DTC) remains stored in the memory.

    Diagnostic Test Mode 1: Fault Code Retrieval.

    * Place the cable into socket 2 (LH2.4 fuel injection test) or 6 (EZK116 ignition test).
    * Turn the ignition ON to KPII without starting the engine.
    * Select Mode 1 by pressing the button once and holding for more than 1 second but less than 3 seconds.
    * The LED lamp will flash in successive series of three digits followed by a three-second pause. If there are no fault codes stored, it will flash 1-1-1 indicating the fuel injection system is operating correctly.
    * Count the successive flashes and record the fault code.
    * Press the button again.
    * Record the fault code. If it is the same as the previous one, then no additional codes are stored. Repeat until all the codes stored are retrieved (maximum of three). If the car is from California you can read up to 17 fault-codes at the same time.
    * Refer to the tables below for the interpretation of fault codes from the LH2.4 Fuel injection System and EZK 116 Ignition System.
    * Move the cable into socket 6 (for ignition codes from EZK116) or socket 2 (for fuel injection codes from LH2.4) and repeat the above.

    Erasing Fault Codes.

    After you have retrieved all the Fault Codes in the steps above, you should erase the system memory.

    * Repeat the steps above and read the fault codes again.
    * Press and hold the button for more than five seconds, then release it.
    * When the LED lights, press the button again for more than five seconds and release. If the LED goes off, then the memory is cleared.
    * To test that memory is cleared, press the button again for >1 second and <3>1 and <3>1 and <3>1 and <3>1 and <3 seconds before pressing again).
    * The diagnostic unit then tests the EGR system controller which you can hear or feel.
    * Exit by switching off the ignition.

    Når vi først har en tråd for feilkodeavlesing og sletting:


    Airbag 940 1993+ (feilkodeavlesing og sletting av feilkoder):
    SRS
    Onboard Diagnostic Codes: 1993+ Cars. Later 940 and 960 cars have an onboard diagnostic system for the Supplemental Restraint System that both monitors the system and stores any fault codes for later diagnosis. Faults can occur in components such as airbags, seat belt tensioners, and the sensor unit or in their associated wiring circuits. A fault is indicated by the
    SRS
    lamp in the instrument panel, which remains "on" until the fault has been remedied and the
    OBD
    system cleared.

    To read faults, refer to the
    OBD
    diagnostic output boxes on the front of the driver's side strut tower. You will find two, labelled "A" and "B". Box "A" has the probe, the test button, and the LED readout.

    Remove the selector lead from the side of "A" and insert it into terminal 5 of output box "B".
    Turn the ignition "on" to key position II.
    Wait about ten seconds.Press the button on box "A". Keep it pressed for about 1 second.
    Read off the LED flashes. Codes have three digits: A-B-C. If code 1-1-1 is read, there are no stored fault codes. If a code other than 1-1-1 is obtained, write it down and press the button again to see if there are more. When the first code recurs, all codes have been read. If you can't obtain any flashing light, see No Codes.
    [Jay Simkin] Always read the codes three times before resetting them. Often they will not reset after just one, or even two readings.


    Fault Codes
    1-1-1 OK: No faults detected in the
    OBD
    system
    1-1-2 Internal fault in the sensor unit
    1-2-7
    SRS
    lamp, short circuit or break in circuit
    2-1-1 Steering wheel module, short circuit in wiring
    2-1-2 Steering wheel module, break in wiring
    2-1-3 Steering wheel module, short circuit to ground
    2-1-4 Steering wheel module, short circuit to +12V
    2-2-1 Passenger module, short circuit in wiring
    2-2-2 Passenger module, break in wiring
    2-2-3 Passenger module, short circuit to ground
    2-2-4 Passenger module, short circuit to +12V
    2-3-1 Seat belt tensioner left, short circuit in wiring
    2-3-2 Seat belt tensioner left, break in wiring
    2-3-3 Seat belt tensioner left, short circuit to ground
    2-3-4 Seat belt tensioner left, short circuit to +12V
    2-4-1 Seat belt tensioner right, short circuit in wiring
    2-4-2 Seat belt tensioner right, break in wiring
    2-4-3 Seat belt tensioner right, short circuit to ground
    2-4-4 Seat belt tensioner right, short circuit to +12V
    No code
    SRS
    lamp in the instrument cluster does not light
    No code Fault in diagnostic output


    To clear fault codes other than 1-1-2 (indicating a crash sensor fault, which must not be cleared but rather returned to the dealer):

    Remember to read the codes three times before clearing.
    Remove the selector lead from the side of "A" and insert it into terminal 5 of output box "B".
    Turn the ignition "on" to key position II.
    Press the button on box "A". Keep it pressed for at least 5 seconds.
    Release the button. The LED lights.
    Press the button again when the LED lights and keep it pressed for at least 5 seconds.
    The codes are now cleared.
    To check whether codes are cleared, repeat procedure A above. If codes remain, then the fault persists and must be repaired.

    [Jay Simkin] If you still have
    SRS
    trouble codes, try this as a last resort. Disconnect the negative battery terminal clamp. Let the car sit for 1/2 hour. Reconnect the negative terminal clamp and drive the car. Do this three times. If the
    SRS
    light re-sets, fine. If not, it is time to replace the
    SRS
    sensor and the power module.


    Cruisecontrol på nyere LH 2.4 biler (feilkodeavlesing):

    Cruise Control Onboard Diagnostic Codes.

    [Editor] Later LH2.4 cars employing two diagnostic modules can directly read cruise control codes. Plug the module pigtail from the "A" unit (this unit has the pigtail connector, the test button, and the LED readout lamp) into position two on the "B" unit. The cruise control system for earlier LH2.4 cars without a "B" unit can be connected to the
    OBD
    system to read diagnostic codes. To do this, run a wire from the extra pigtail on the cruise control unit connector at the left side under the driver's kick panel to the
    OBD
    diagnostic connector in the engine compartment (the pigtail you plug into the various holes.) The system must be tested with the ignition "On" and after roadtesting above 35 km/h (22mph) since the unit does not store codes, only reports them, and erases all codes when the ignition is turned off. The following is a brief excerpt from the
    OEM
    manual.

    There are two diagnostic modes:

    Mode 1: Self Diagnosis
    Ignition "On" after roadtest, diagnostic wire connected. Press diagnostic button once for one second. Read the code.(If nothing flashes, see No Code.)Check for another code by pressing again for one second. Repeat until the first code is returned. This test returns various error codes from the road test.

    1-1-1 No faults detected; speed has exceeded minimum 35 km/h needed for test

    No fault

    1-1-2 Abnormal speed signal
    Possible static in speed signal to control

    1-2-2 No speed signal, or has not exceeded minimum 35 km/h
    Voltage feed (12V between terminals 10 & 11)
    Ground location (0 ohm between terminal 10 and ground)
    Speed signal
    Wiring in circuit (speedo to control unit; speedo to rear axle)
    With rear wheels raised and one rotating slowly,voltage at terminal 13 should oscillate 12V to +1.5V

    2-1-1 Voltage feed or cruise control unit malfunction
    Minimum 10.5 V at terminal 11

    2-1-2 Malfunction in the circuit to vacuum pump or regulator
    Test vacuum system first
    12 V between terminal 2 and ground
    12 V between terminal 10 and 11
    Ignition Off, selector On: Check wiring for resistance


    Mode 2: Component Test
    Ignition "On", diagnostic wire connected. Start with cruise selector switch "Off" and the transmission in "Drive". Press the diagnostic button twice, each for one second. The LED shoud flash rapidly. Then perform the following tests in the order listed to test each component of the cruise control system. Faults may be pinpointed to the components or circuits noted.


    Activated Component: Brake light switch
    Action: Depress brake pedal for one second
    Code: 1-3-2
    Fault: If no code: brake light circuit


    Activated Component: Selector ON and OFF, brake and clutch valve Action: Depress brake then clutch pedal for one second
    Code: 1-1-3
    Fault: If no code: brake and clutch valve


    Activated Component: Selector RESUME
    Action: Press RESUME for one second
    Code: 1-2-3
    Fault: If no code: resume button


    Activated Component: Selector SET
    Action: Press SET for one second
    Code: 1-3-1
    Fault: If no code: set button


    Activated Component: Start inhibitor switch
    Action: Shift transmission to NEUTRAL
    Code: 2-2-3
    Fault: If no code: start inhibitor switch

    If code 3-1-1 is reported during any test: Several simultaneous signals: short in circuits

    Hvordan ser man tallene på feilkoden når man leser av på bilen?
    Om koden f.eks er 3-2-1, blinker det 3 ganger på det "første blinket", 2 på det neste og 1 på det siste?
