附 录原文:Electrical Systems-Other Auxiliary Equipment Faults and ProblemsM73 Secondary Air Pump Circuit RewiringModel:BMW E38-750iLA with M73 engine produced between August 1998 and October 1998.Complaint:Due to the wiring for the secondary air circuit at the Engine Control Modules being reversed,the illumination of the check engine light may result causing the fault FC 79 (4F)-Undefined.Remedy:Utilize the Service Menu of the Dealer Communication System,and based upon the response of the system either proceed with corrective action,or take no action at all.If action is necessary the wiring in module connector number 4 of DME I pin 3 and DME II pin 31 must be swapped.Reprogramming of Engine Control Module May Not Be PossibleModel:BMW E38-740i/iLA with M62 engine and DSC 3 produced as of September 1998.BMW E38-540i/iA/iTA with M62 engine and DSC 3 produced as of September 1998.BMW E38-528i/iA/iTA with M52 engine and DSC 3 produced as of September 1998.Complaint:Due to the DSC 3 control module troubling the communication path between the DIS/MODIC and the DME and/or EGS module,the reprogramming procedure is unable to peform and the following message is displayed:”Programming cannot be performed correctly!Test code 002400.Repeat programming if necessary.”Remedy:Before starting the programming operation the power supply to the DSC 3 module must be removed.Vacuum Hose to Secondary Air Non-Return Valve.Model:BMW E46-323i/iA,328i/iA produced between April 1998 and July 1998.Complaint:The vacuum hose going to the Secondary Air Non-Return Valve may be wrongly routed.Consequently if this hose connects with the exhaust system it may set off the following faults may set within the Engine Control Module(ECM/DME):-Fault Code 245(F5 hex)-Flow rate secondary air rate too slow bank 1.-Fault Code 245(F6 hex)-Flow rate secondary air rate too slow bank 2.Remedy:Utilize the Service Menu of the Dealer Communication System,and base upon the response of the system either proceed with corrective action,or take no action at all.If action is necessary then check the condition and routing of the vacuum hose going to the non-return valve on all affected vehicles if required reroute.If fault code 245 or 246 ate set in the DME the vacuum hose going to the non-return valve will need to be replaced if it is damaged.Motronic M1.1-Circuit SuppressionModel:BMW E32(735i),BMW E30,BMW E24,Equipped with M1.1 Fuel injection 1987 and 1988 Model Years(prior to 5.88 production).Complaint:M1.1 control unit durability can be affected by migrant voltage surges from the “Check Engine” light circuit.Remedy:The following Service Action is necessary:Install suppression diode harness(P/N 88 88 2 000 100).Idle Mixture Check and Adjustment(after major engine repair)Model:BMW M3,BMW M5,BMW M6Complaint:M3,M5 andM6 cars that do not have CO-screws on the exhaust manifold pipes may need the idle mixture checked and adjusted after major engine repair.Remedy:Follow this procedure to ensure the idle mixture is correctly adjusted if necessary.-Engine is at operating temperature;the oil needs to be at least 60 degrees C or 140 degrees F.-The ignition timing and valve clearance are correct.-The plate synchronization is correct.-The idle speed is correct.-All electrical consumers and air conditioner must be switched off.-Connect the digital mixture measurement unit (integrator voltage measuring unit for 318i-P/N 88 88 6 126 400) to engine diagnosis socket (BMW service tester cable is connected to digital mixture measurement unit).-Start engine.-Flashing of the red LED at regular intervals indicates normal operation of the oxygen sensor.-Read integrator voltage on LCD display.If necessary,adjust to a value of 6 plus/minus 3 volts at the airflow meter bypass screen while the red LED pulsates at a regular interval.-If the red LED stays ”on” continuously,the engine idle speed mixture is too lean,or the oxygen sensor is defective.-If the red LED stays ”off” continuously,the engine idle speed mixture is too rich.-Adjust the idle mixture by carefully turning the airflow meter bypass screw to a value of 6 plus/minus 3 volts,until the LED flashes at a regular interval. -Check the engine idle speed and integrator voltage.Idle Control Valve Binding-No StartModel:BMW E36 with M44 engine.Complaint:Due to a binding idle control valve the engine may not start or will only start when the accelerator pedal is depressed making the throttle plate open.This is causing by the air gap between the rotary slide valve and the idle control valve housing being too small which causes the valve to bind in the closed position.When this happens the throttle plate by-pass air is restricted during cranking causing the engine not to start to very difficult to start.Remedy:A new style idle control valve part number 13 41 1 435 846 should be installed.Whistling Noise from idle Control ValveModel:BMW E36 with M44 engine.Complaint:The idle control valve can emit a whistling noise when the engine is at idle.This is due to adverse tolerances between the idle control valve housing and the rotary slide valve.Remedy:A new style idle control valve part number 13 41 1 435 846 should be installed.RelaysModel:All BMW.Complaint:If a relay sticks in the closed position after the ignition is turned off the following complaints could arise.-The auxiliary fan continues running.-A/C-heater blower motor continues running.-Fog lights and/or headlights stay on.-The battery goes dead overnight.-The rear window defogger stay on.This is due to the battery voltage still being present when the ignition is turned off.Apart from the auxiliary fan the componets need their control switch left on for the situation to occur.The auxiliary fan will automatically continue running in this condition.Remedy:Replace the defective relay.Vibration Resistant BatteryModel:BMW E36 Convertible.Complaint:Not only is the E36 convertible battery an energy source it is also a vibration damper.The battery also has a special battery tray with integrated vibration absorber.Remedy:If the battery needs to be replaced a vibration resistant one must be installed.Hints and Tips:Audi idle speed problemsEngine stalls at idle speed or stalls after the start Vehicle has no idle speedCause:Coking causes the piston in the idle stabilization valve-N71 to jam.Models affected:ABK engine from MY 95.Service:The idle stabilization valve-N71should be checked according to the workshop manual.If the valve sticks.Attach the modification kit for changing the air intake point for the idle stabilization valve-Part No.048 198 455.Replace the idle stabilization valve-N71-Part No.048 133 455.Idle speed which is either fluctuating or excessiveCause:The idle speed components are lacking electronic adjustment after a voltage loss in the system(for example after the disconnection of the battery,control unit change and a problem with the voltage).Models affected:ABK,ABC engine.Service:Referring to the workshop manual do a basic setting with V.A.G 1551.Throttle valve potentiometers and idle stabilization valves have been unnecessarily changed too often because of lacking system adjustment.If the complaint is not corrected with the basic setting,then a component is defective.It must be located by referring to the workshop manual.Poor accelerator response or the engine stalls when in the warming up stage whilst being station at traffic lights for instance.Cause:In the control unit the cold initial running set is too thin.Models affected:AHL engine.Service:Part No.3B0 907 557 A for improved control unit.Identification on the sticker”5WP4351”,data ver”D05”.Wavering idle speed with cold/warm engine.Cause:A smaller vacuum hose branches off from the crankcase ventilation,which is routed as bypass around the throttle valve.Especially in winter the throttle hose and/or the vacuum hose can become clogged and/or iced up with crankcase condense water.Consequently the idle speed wavers by several 100 rpm during the phase of warming up,gradually dying down as the engine heats up.Pulsations in the air inlet hose are possible through the crankcase ventilation.This leads mainly to wavering idle speed with switched on electrical consumers and air conditioning with a warm engine.Model affected:ADP engine 1.6 L.Service:Take away the intake hose complete with crankcase ventilation hose and vacuum hose.Clean the throttle hole,2 mm (4) diameter,and hose of vacuum (3).Take away the cylinder head cover,put in the new oil splash guard and get rid of the old one-Part No.06A 103 544 (unscrewed).Adjust the cylinder head cover and intake hose.Do not lose the O ring and make sure it doesnt lose itself in the neck of the crankcase ventilation hose.A tiny wavering of idle speed by approx 50rpm when the vehicles is still rolling and the clutch is pressed down is no cause for concern and is normal.When cold or even just after more than 20 seconds or so the engine doesnt start.There is a vehicle breakdown and no fault is stored in the fault memory.Cause:Engine adjustment.Models affected:ACK engine (142 KW) from MY 96.Service:1. Looking at the fault memory of the engine control unit.Investigate the vehicle according to the workshop manual if a fault has been stored.2. See if the basic setting of the throttle valve control unit is correct,if necessary reset it.3. If the basic setting is all right and if no fault has been stored,take out the spark plugs and clean them,then replace.4. Part No.4D0 907 551 B-with data version D09-fit control unit.译文:电子系统-其他辅助设备的缺点和问题M73第二空气泵电子线路举例:在1998.8-1998.10间生产的带有M73型号发动机的BMW E38-750iLA。缺点:因为在发动机控制模块中的第二空气循环线路混乱,检查发动机的照明灯将导致不确定的故障-FC 79。改正:利用经销商通讯系统中的维修菜单及其回复进行纠正或不采取行动。如果必须纠正,应使4号线路中的DME I 3和DME II 31交换。不可以改编发动机控制模块举例:在1998.9生产的带有M62型号发动机和DSC 3的BMW E38-740i/iLA。在1998.9生产的带有M62型号发动机和DSC 3的BMW E38-540i/iA/iTA。在1998.9生产的带有M62型号发动机和DSC 3的BMW E39-528i/iA/iTA。缺点:因为DSC 3控制模块混淆了DIS/MODIC、DME和/或EGS模块间联系的线路,改编程序不能完成任务。将显示如下信息:“程序不能正常进行!如果需要,测试代码002400重新编程。”改正:在编程操作前必须移走提供给DSC 3模块的动力。第二空气非循环真空管举例:在1998.4-1998.7间生产的BMW E46-323i/iA,328i/iA。缺点:第二空气非循环真空管不恰当的发送气体。总地来说,如果与排气系统连接,真空管能防止发动机控制模块内部的故障。如下:-错误代码245(F5 十六进制)-储存库1中空气流动速率过慢。-错误代码245(F6 十六进制)-储存库2中空气流动速率过慢。改正:利用经销商通讯系统中的维修菜单及其回复进行纠正或不采取行动。如果必须纠正,需检查所有影响汽车非循环真空管中气体的环境和行程是否需要改变。如果错误代码245、246出现在DME真空管的内部,且设备毁坏则需更换真空管。M1.1-循环抑制举例:在1987年和1988年生产的带有M1.1燃油喷射装置的BMW E32 (725i),BMW E24。缺点:检查发动机照明循环设备中的电压振荡影响M1.1控制个体的耐久力。改正:有如下建议:安装控制二极管(P/N 88 88 2 000 100)。空转混合控制和调节器(在主要发动机修理后)举例:BMW M3,BMW M5,BMW M6。缺点:排气系统中各个管没有联合螺钉的M3,M5和M6汽车,在主要发动机修理后需要空转混合检查装置和调节装置。改正:如下步骤确保空转混合装置正确调整:-发动机运转温度:油液需要至少60摄氏度或140华氏度。-注意点火正时和气体管的清理。-同步电镀要正确。-空转速度要正确。-所有的电子设备和空气调节设备要切断。-将数字混合测量设备连接到发动机诊断插座上(综合电压测量为318i-P/N 88 88 6 126 400),(宝马检测电缆与数字混合测量设备相连)。-运转发动机。-红色发光二极管规则闪亮指示氧传感器正常工作。-读出液晶显示器指示的综合电压。如果需要,在气流仪表旁显示屏上原来的6伏基础上,增加或减少3伏电压,使红色发光二极管以规则的时间间隔闪亮。-如果红色发光二极管一直保持“亮”的状态,则发动机空转时的混合气太稀,或氧传感器有故障。-如果红色发光二极管一直保持“灭”的状态,则发动机空转时的混合气 太浓。-通过小心调整气流仪表旁螺钉增加或减少3伏电压来调节混合气的浓度,直到发光二极管以规则的时间间隔闪亮。-检查发动机空转速度和综合电压。空转控制阀弯曲-不能工作举例:装有M44型号发动机的BMW E36。缺点:有弯曲空转控制阀的发动机不能工作或仅当压下加速踏板使节流阀打开时才工作。这是因为在旋转滑动阀和空转控制阀机架间空气缺口太小的原因,这导致控制阀粘住相近的活塞。当这种情况发生时,节流阀旁路空气是有限的,使曲轴不能或很难使发动机工作。改正:安装新型空转控制阀部件,型号为1 3 41 1 435 846。空转控制阀噪声举例:装有M44型号发动机的BMW E36。缺点:当发动机空转时,空转控制阀产生噪声。是因为在空转控制阀机架和旋转滑动阀间有不利的公差存在。改正:安装新型空转控制阀部件,型号为1 3 41 1 435 846。继电器举例:所有的宝马车。缺点:在点火停止后如果继电器粘住相近的活塞,将出现下面的问题:-辅助风扇继续运转。-A/C加热吹风电动机继续工作。-烟雾灯和/或前车灯继续点亮。-电池整晚工作。-后车窗除雾器一直工作。这是因为当点火停止时,电池电压继续存在。除了辅助风扇外,总体构成需要他们控制左边部分的位置转换。在这种情况下,辅助风扇将自动地一直工作。改正:更换有故障的继电器。抗震电池举例:BMW E36缺点:E36抗震电池不仅仅是动力来源也是抗震装置。这种电池有一个特殊的电池圆盘作为震动吸收器。改正:更换抗震电池。提示和信息:奥迪速度问题在有空转速度和无空转速度时,发动机停止运转。原因:燃烧杂质堵塞空转稳定阀N71的活塞。影响举例:MY95的ABK发动机。建议:根据车间工作手册检查空转稳定阀N71。如果阀门堵塞,用工具箱改变空转稳定阀部件048 198 455的进气口。替换空转稳定阀部件048 133 455。空转速度或上下变动或增多原因:在系统中,电压减小后空转速度构成缺少电子调节器的调节。(例如,不与电池相连后,控制单元改变,电压产生问题)影响举例:ABK,ABC发动机。建议:查阅车间工作手册后对V.A.G 1551做个基本的装置。因为缺少调节系统,不需要经常更换节流阀电位分压计和空转稳定阀。如果问题还没有解决,说明这是个有故障的构成。需要重新定位于车间工作手册。例如在货车上是固定的原因:在控制单元里冷机执行运转设备太薄弱。影响举例:AHL发动机。建议:改进部件3B0 907 557 A的控制单元。在粘合剂上鉴定”5WP4351”,数据译本”D05”。冷/热发动机空转速度的波动原因:从曲轴通风管分出的小段真空管作为旁通路与节流阀相通。特别在冬天,节流管和/或真空管阻塞或被曲轴通风箱内的结晶水冻上。总的来说,在启动阶段空转速度大约在每分钟100转左右,并逐步衰减直到发动机发热。在空气入口管处的震动可能通过曲轴通风箱,这主要导致热机时空转速度波动,电子设备和空调工作。影响举例:1.6升ADP发动机。建议:取走进气管同曲轴通风管和真空管。清理2/4毫米直径的节流口和3毫米直径的真空管。取下气缸盖,放入新的挡油板,拿走旧的部件06A 103 544(拆修)。调整气缸盖和进气管。不要忘了密封圈,确保它在曲轴通风管处。当汽车正常运转,离合器被压下。大约每分钟50转的空转速度有微小的波动属于正常现象。发动机不能启动或在20秒以后仍不能启动。汽车分类和没有错误存储在错误存储器中。原因:发动机调整设备。影响举例:MY96的ACK发动机(142KW)。建议:1.在发动机控制单元里查找错误存储。如果错误存在,根据车间工作手册研究汽车。2.查看节流阀控制单元设备是否正确。如果需要,重新设置。3.如果基本设备都正确且错误没有被储存,则取出火花塞并清理干净,然后换上。4.部件4D0 907 551 B有数据译本D09-适合控制单元。
