Hi, My truck has always had the check engine light on. It's nothing serious(i'm pretty sure). It runs fine and i have never had any real trouble with it. But that light is starting to make me nervous. I am thinking about getting an OBDII tool. A cheap OBD tool (maybe the actron pocket scan) would be a good investment because it would probably pay for its self. My truck has 2 places to plug in to, the OBDII connector under the steering wheel and a EEC connector by the fuse box under the hood. The OBDII tool i want only can connect to an OBDII port. My truck is a 1997 ranger so i'm sure that it is OBDII and according to my shop manual my electronic engine control is an EEC-V. From what i have read the EEC has some sort of diagnostic feature. This may be a stupid question but this is kinda new to me. Does the OBDII give the same information as the EEC?
OBDII is a diagnostic system mandated by the government. The EEC PCM is a microprocessor that controls many engine, transmission and emission components. By far, the best deal I have seen for an OBDII code reader is $40 from Harbor Freight Tools. All OBDII readers plug into the Data Link Connector under the dash. If you unplug the PCM connector itself, the PCM will power down and all codes will be lost.
Be sure that you don't get an OBD or OBDI reader - it is not compatible with your truck.
I got an OBD-II to laptop USB cable from Amazon for less than $10.... There's a lot of freeware available online to read and reset codes... I'm using "wOBD" on my laptop to read and reset codes... the software will also do a lot more...
They have a bluetooth adapter you plug into your odb2 port that transmits the data to your phone or tablet. Unfortunately it will not work with Apple products because apple want too much for the rights to their bluetooth stack codes.
Looks pretty cool though. Does all the stuff a reader does and gives you allot of performance data.
mine's the USB version of the same thing... the Windows 7 laptop I'm using doesn't have Bluetooth... A Mac (or Linux) user would need to comment on the availability/capability of OBD-II software for that platform.
