OBD II Gurus Help!!

My jeep started showing a check engine light today. I clicked the Ignition 3 times and Then waited, No reading on the Odometer, no flashing check engine lights only 5 beeps.

Normaly it only beeps 4 times.. What is up? Why am I not getting Code, or DONE appearing in the odometer read out or nothing..

The Autozone here will scan your computer for free. Maybe you have an Autozone near you that will do it also?

Re: OBD II Gurus Help!!

1. Unless you have an OBDII scanner...
2. You can't recover ALL the codes...
3. Of course there's the DIY laptop connectors and software...

Re: OBD II Gurus Help!!

I'm pretty sure you're going to need a scanner to diagnose this. Careful though, I borrowed a scanner for my '95 Ranger not too long ago when my check engine light came on. Said I needed a "Purge Control Valve". Figured out what it was, got a new one, slapped it on, and cleared the code. Code was back in a couple of weeks. Fought with it for a couple of months before calling Ford and they told me they always replace another valve in the same line at the same time. Wasn't mentioned in my books. When you do get a scanner and find the code, it's a good idea to make sure that there is only one part you need to replace. I ended up hassling with it for nearly three months before I broke down and called the dealer. Took them 2 minutes on the phone to tell me the problem, and me less than five to put te new piece in at the dealership.

Good luck with it, and please let us know how it comes out!

A scanner is your best bet to truly get the code. I love having acess to a scanner at school. I've found most of the time i re-set the code and don't have any problems after that.

You need a scanner to get the codes... If Autozone has a scanner it wil be a "generic" obdII scanner. The dealer will have a dianostic tool that will be able to retrieve more info from the car than autozone will.

MOre and more, they are building vehicles so you HAVE to go to the dealer to get them fixed. Smalll time garages that can't afford the expensive diagnostic tools can't fix them any more. You may end up spending more buying part after part until it is fixed.

May want to bite the bullet at take it to a dealer for the diagnostics, and then buy the part and put it on yourself.

BTW, if the light is not flashing when you drive it and it seems to run fine (not rich, overheating, or missing), then you could probably drive it without any other complications. Unless you need to go in for a smog check.

Re: OBD II Gurus Help!!

It runs better now than it has in months, I replaced the spedo gear, the spedo quit right before the code came up. Kinda makes me think I have a loose connection somewhere
