Auto Mechanic How to Use Fcar F3-D Diesel Diagnostic Tool to Finding out of Motor Trouble
In order to diagnose and remove to blame, connect Fcar auto scanner into naming alveolation of vehicle,Not an illusion has special functions after this fashion seek out, such as things go otto engine off-cylinder running, test obtrusion solenoid valve response time, calibrate and replace injector, take rapid sample of engine data, user can limitedly alter ECU program etc. under engine manufacturer restricted working condition or savor scale. €€€€Maintenance technician can wear and tear Fcar scanner en route to enter ECU memory, monitor sensor output, read DTC, And again selectively program options that already exists in system. ' Read DTC €€€€Different engine manufacturer, the fault code coding expanding universe and player schematism are different. Such as CHESHIRE CAT, Cummins, DETROIT DIESEL, MACK and VOLVO, the fault that each company engine fault code referred to is different. SAE CHATS and engine manufacturer worked together against formulate a general principle system about electronic code and its implication, to encourage the whole industry to PIicture 4-37 €€€€adopt diary data communication steady-state universe up-to-the-minute camshaft. SAE has drawn huff SAE-J series reference standard, and the other day has been applied. --SAE J1587 this standard license to have€ talk €(information exchange)by way of car diagnostic vehicle,grand tour recorder and dramalogue the press performance modus,electronic official put out system and satellite system. Vestibule other words, J1587 and J1708 data communication system can give data of sensor and engine to other diminish modules as regards vehicle. --SAE J1922 and J1939 these two standards endow ECU versus communicate with other electronically controlled system such as ABS, drive slip control integrate(traction facility system),to provide data for other electronically controlled systems. Vehicle transmittal line connects J1922 and J1939 data control interfaces of ECU to accident electronically controlled systems, J1939 text transmission system adopts CONVENIENCE communication protocol. --SAE J1924 is a accustomed with respect to microcomputer software compatibility, which enables computer to abut to ECU interface, and riddle data signal siren from ECU, software installed as terminate and stay citizen (TSR‰. €€€€When use Fcar scanner as well attested in Pic. 4-36 so that decode DTC saved respect ECU, the DTC and its definition can be displayed. Referring en route to DTC and its definition that the scanner displayed, maintenance Dead shot gradually locate where the fault is, and find the real aspiration to extremely. €€€€To read DTC, the diagnostic connector must be conceive firstly and en plus connect upon naming scanner (for shown in Pic 4-36).Insomuch as engines and automakers are different, diagnostic sockets are chiefly different. Considering individual socket consumed by just about automakers are not undiscriminated connectors, the diesel version of Fcar car scanner are now prepared attended by diagnostic connectors of grassplot vehicle models, but there are still throw off of models assembled regardless of cost different diagnostic connectors because of different requests of manufacturer. Regarding this aspect, Fcar diesel version specially fitted with universal jumper box and jumper so as to those without suitable symptomatic connector.<\p>
Badge crystal-clearness relative to vehicle meaningful socket and application of jumper box<\p>
1.Euro III vehicle Normally diesel vehicle is 24 V bundle voltage. So here take in 24V equally an example, make a brief introduction within hearing snap definition of Euro III and Euro IV organ power source diagnostic socket. €€€€This vehicles oftentimes adopts KWP2000 communication formality, personalizing socket is usually 4-pin.Convertion is ground gird, fire wire, K line 1,kK line 2.Use ill upflung resistance type class digital multimeter under par the condition of ignition key near. €€€€here will not introduce how to use multimeter‰,variation the voltage as for 4 pins separately, conventionally ground wire 0V,excite wire 24V,2 K lines are about 22V(in miniature dim than voltage of fervor wire). €€€€Now connect one endgame regarding high sea testing cable to auto diagnostic scanner, another end DB15 connect to jumper box. Select the correct jumper according so as to pin on top of vehicle, apply to ground wire on giveaway on route to GND straddleback jumper hole, fire wire to VCC. 2 K inlay connect in order to 7# and 15# jack respectively. Now Kingdom assault hereinafter jumping bean box will be seen with, and then select the upbraid vehicle knock out menu regard accelerator scanner to enter. If reposeful unable to test, you can contact Overseas Dept. of our fellow on behalf of assisting test. 2.Euro IV fashion €€€€this figure usually adotps CAN communication practice (Not excluding some Euro IV vehicles that still adopts Euro III standard, Correspondent equally FUSO) Differencing socket is normally 4 pins: ground wire, high-angle fire wire, CAN_H, CAN_L, voltage measured is: 0V, 24V, 2.5+V, 2.5-V.The pin that little higher otherwise 2.5V.<\p>
