What is FORScan?

FORScan is a software scanner for Ford, Mazda, Lincoln and Mercury vehicles, designed to work over ELM327 and J2534 Pass-Thru compatible adapters

There are many OBD2 scanners, but does the FORScan somehow differ? Yes, because it is designed especially for Ford, Mazda, Lincoln and Mercury vehicles. So supports specific features of the manufacturer protocols, making the FORScan more powerful in work with these models than any regular OBD2 scanner.

For example, FORScan can detect modules which are not visible for regular OBD2 scanners, can show you trouble codes which are never displayed by OBD2 scanners, can show you PIDs which are not supported by any OBD2 scanner, run specific tests and service procedures. In other words, FORScan can do things that regular OBD2 scanners can not do.

Main features

  • Detect vehicle on-board network configuration
  • Read and reset Diagnostic Trouble Codes from all modules (see list of supported modules)
  • Reading of modules' sensors' data
  • Run test diagnostic procedures (not supported in FORScan Lite yet)
  • Run service procedures (not supported in FORScan Lite yet)

    Supported vehicles:

    All Ford, Mazda, Lincoln, Mercury vehicles that can be addressed by supported adapters. It is 99% of models after 2000 and around 92% of models after 1996 (the year when OBD2 became a standart in USA).

    Supported adapters :

  • ELM327-compatible (fully compatible with original ELM327, please see important note below)
  • J2534 Pass-Thru
  • CANtieCAR (in "FORScan" mode)
  • OBDLink SX/MX (STN11xx)
  • ELS27 (STN1170)

    Important note: almost all of adapters sold under "ELM327" label are "clones" (use not original ELM327 chip). In past few years 80% of them are "bad" clones, and unfortunately this ratio grows. "Bad" clones are not fully compatible with original ELM327 and will not work with FORScan. FORScan uses service level protocols and requires adapters that are fully compatible with original ELM327. Other software that uses standard OBDII protocol usually work with these adapters, so people usually don't understand the problem. The problem is that service protocols are more complex than regular OBDII ones and this is why it is physically impossible to make FORScan work using these devices. We recommend to obtain either original white-label adapters listed above (Scantool OBDLink, ELS27), or look for ELM327 marked as "Ford Mazda FORScan" etc compatible - these are usually "good" clones equipped with HS/MS CAN switch. But "good" clones may have other problems (for example, USB adapters cannot work faster than on 38400 bps, CAN bus errors etc).

    Supported protocols and bus:

  • FORD HS CAN
  • FORD MS CAN (only for J2534-2, CANtieCAR, OBDLink MX, ELS27 or modified ELM327)
  • FORD SCP
  • FORD 9141
  • FORD UBP (only for Ford VCMII)

    Supported modules:

    Almost all of modules availabe through supported protocols. Full list is here.

    Supported platforms:

  • Windows 2000/XP/Vista/7/8/8.1/10 (COM, USB, Bluetooth and WiFi adapters)
  • iOS v6.0 and higher (WiFi adapters)
  • Android v4.0 and higher (Bluetooth and WiFi adapters)

    Platforms in development:

  • Windows Phone 8 (Bluetooth and WiFi adapters) - development temporarily freezed
