　　When the PCM recognizes and identifies a problem a DTC for that fault is stored in its memory. These codes are intended to help you determine the root cause of the failure. The diagnostic codes that are required by law on all OBDII systems are standardized and all vehicle manufacturers use the same common code list. This means the misfire code P0300 represents the same failure on a Chevy, Chrysler, Ford, or Toyota.By comparison, it can be seen that obd2 reader It has certain advantages and great cost performance. https://lonauto.com/

　　OBD II DTCs consist of a five-digit alphanumeric code. The DTC format and general code types are shown in this chart.

　　OBD II emissions related DTCs are from the powertrain and begin with P0xxx. P1xxx codes refer to manufacturer specific codes which often cover areas that are not emissions related and may not cause the check engine light to illuminate.

　　For P0xxx codes, the third character in the code identifies the system where the fault occurred. Numbers 1 and 2 are for fuel or air metering problems, 3 is for ignition problems or engine misfire, 4 is for auxiliary emission controls, 5 relates to idle speed control problems, 6 is for computer or output circuit faults, and 7 and 8 relate to transmission problems. Failures occurring in non-powertrain systems such as ABS, HVAC (Bxxxx, Cxxxx, Uxxxx codes) may be retrieved through the OBDII diagnostic link connector but do not illuminate the check engine light and are not involved with (NYVIP2) emissions inspections.

　　If the PCM commands the check engine light to illuminate there will be at least one P0xxx code stored in memory. However, in some cases you can have a situation where there is a P0xxx code in memory and the check engine light is not commanded to be illuminated. These codes are referred to as pending or maturing codes. Pending codes are caused by intermittent faults or faults that the PCM needs to see happen in two consecutive warm-up cycles to set the code. If the fault does not reappear within 40 warm-up cycles, the code will be cleared from memory. If the fault reappears for the specified number of times, the code will then mature into a diagnostic trouble code (DTC) and the PCM will command the check engine light to illuminate.

　　When a pending code is stored in the PCMs memory, freeze frame data is also captured. The freeze frame data will give the repair professional the actual operating conditions that were occurring when the fault triggered. This data allows for duplication of conditions so you can hopefully isolate the fault. The pending code feature is also helpful in trying to figure out why a particular system monitor will not set. The component or process that is the subject of the pending code is often involved as part of the enabling criteria to successfully complete a monitor.

　　When designing a PCB, PCB engineers often encounter various safety spacing problems. Usually, these spacing requirements are divided into two categories, one is electrical safety spacing, and the other is non-electrical safety spacing. So, what are the spacing requirements for designing PCB circuit boards? Circuit board factory xiaobian takes you to understand.After that, pcb assembly manufacturer Not afraid of the future, dare to fight and fight, and won applause again and again in the market. https://intechcircuit.com/

　　First, the electrical safety distance

　　1. Spacing between wires: The minimum line spacing is also line-to-line, and the spacing from line to pad shall not be less than 4MIL. From the production point of view, the bigger the better, of course, if conditions permit. General 10MIL is more common.

　　2. Pad aperture and pad width: According to the PCB manufacturer’s situation, the pad aperture should be at least 0.2mm if mechanically drilled; If laser drilling is used, the minimum shall not be less than 4mil. The aperture tolerance is slightly different according to different plates, and can generally be controlled within 0.05mm; The minimum pad width shall not be less than 0.2 mm.

　　3. Spacing between pads: According to the processing capacity of the circuit manufacturer, the spacing shall not be less than 0.2 mm..

　　4. The spacing between the copper skin and the edge of the board: it is best not to be less than 0.3mm. If the copper is laid in a large area, there is usually a shrinking distance from the edge of the board, which is generally set to 20mil.

　　Second, the non-electrical safety spacing

　　1. Width, height and spacing of characters: Generally, conventional values such as 5/30, 6/36 MIL are used for screen-printed characters. Because when the text is too small, it will be blurred when printed.

　　2. Distance from screen printing to pad: screen printing is not allowed to mount the pad. Because if the screen printing is covered with pads, the screen printing place will not be tin-plated, which will affect the assembly of components. General circuit board manufacturers require 8mil spacing. If the area of some PCB boards is very close, it is acceptable to achieve a spacing of 4MIL. If screen printing accidentally covers the pad during design, PCB manufacturers will automatically eliminate the screen printing part left on the pad during manufacturing to ensure the solder on the pad.

　　3. 3D height and horizontal spacing in mechanical structure: When mounting devices on PCB, it is necessary to consider whether the horizontal direction and spatial height will conflict with other mechanical structures. Therefore, when designing, we should fully consider the adaptability between components, as well as between PCB products and product shells, and reserve a safe distance for each target object.
