A scan tool allows you to read faul codes and other diagnostic information. READING TROUBLE CODES. On most 1. 99. 5 and older pre OBD2 domestic vehicles, diagnostic trouble codes can be read manually by grounding or jumping certain terminals on the vehicles diagnostic connector. This puts the powertrain control module PCM into a self diagnostic display mode, causing it flash out the code via the Check Engine Light Malfunction Indicator Lamp or MIL. You then look up the code number in a reference chart to find out why the light is on. The problem with reading manual flash codes is that 1 they are no longer used on most 1. Nissan, and 2 counting the series of flashes can be confusing. Most flash codes use a combination of long and short flashes to indicate double digit codes, and if the vehicle has more than one code, it may be tricky to tell when one code ends and the next one begins. So the preferred method of reading codes on older vehicles is to use a code reader or scan tool. On 1. 99. 6 and newer vehicles with OBD2, there are no manual flash codes. You must have a code reader or scan tool to read the codes. CODE READERSThe most basic diagnostic tool is a code reader. A code reader can access and display codes from your vehicles computer. The least expensive models only display a number while the better ones also provide a definition some are even bilingual and can display in English, Spanish or French. Code readers typically sell for under 5. A code reader can also clear codes to turn off the Check Engine light. Some code readers can also display the ready status of various OBD II monitors ready means the monitor has completed its self check process. But a code reader is NOT a scan tool because it only reads and clears codes. View and Download Chrysler 300M service manual online. ChryslerDodge. 300M Automobile pdf manual download. It does NOT display any sensor data or other system operating information. To read sensor and other system data, you need some type of scan tool or scanner software. An important point to keep in mind here is that a fault code by itself does NOT tell you which part needs to be replaced. The code only tells you that a fault has been detected, not what caused it. The code serves as a starting point for further diagnosis. Many people dont understand this and assume an inexpensive code reader is all they need to diagnose and repair their vehicle. Also, dont assume all code readers display all codes. They all display generic or global OBD2 codes P0 codes. But some do not display manufacturer enhanced codes P1 codes, or if they do, the list of codes may be limited to domestic vehicles Ford, GM Chrysler and not include any enhanced codes for Asian or European vehicles. Something else to check before you buy is the model years the code reader can access. Most code readers are for 1. OBD2 vehicles with a standard OBD2 1. Most code readers cannot read codes on 1. However, vehicle specific code readers are available for older GM, Ford or Chrysler applications. The same is true for BMW, MINI and some other import applications. Something else to keep in mind about code readers and scan tools, is that the list of new DTCs and system data grows with every new model year. Last years tool may not work on next years models. Tools get out of date VERY quickly, and have to be updated with new software via plug in memory chips, cartridges or internet downloads from the tool supplier. If you are shopping on ebay for a used code reader or scan tool, make sure it will work on your vehicle, or can be updated to your vehicle. One thing to watch out for when shopping DIY scan tools is that they may not cover newer vehicles that are less than 4 or 5 years old. Check with the scan tool manufacturer to see what is the most recent model year covered, and how often updates will be offered. See Keeping Your Scan Tool Up To Date for more information about software updates. SCAN TOOLSFor advanced diagnostics on todays vehicles, a full feature scan tool is an absolute must. Scan tools for do it yourselfers can display sensor values and system data, but DIY scan tools cannot perform various system self tests such as checking the operation of the fuel pump, cooling fans, idle speed control motor or solenoid, EGR solenoid, AC compressor clutch, fuel injectors, EVAP leak test, EVAP purge controls, etc. This level of diagnostics requires a professional level scan tool which are EXPENSIVE with bidirectional two way communication capability and the proper software for accessing and running these type of tests. Celtic Frost Prototype more. Scan tools have different ranges and capabilities. Entry level generic scan tools typically sell for less than 2. They can read and clear codes, display the status of the various OBD II system monitors, and display basic operating data such as loop status Open or Closed, airflow, coolant temperature, oxygen sensor outputs, throttle position and other sensor readings, and fuel trim values for diagnostic purposes. Most of these tools are fairly versatile and work on all domestic makes Ford, GM Chrysler, but may require additional software for Asian andor European applications. Entry level scan tools that are sold in auto parts stores are usually designed for do it yourselfers, and lack bidirectional communications capability for liability reasons.
