I recently bought a 97 Honda Accord Ex 4cyl. The car is all stock from what I can tell. Just got a service engine light. I tried to find the service port connector (ALDL), but there is not one on my car. It appears a previous owner has cut it out and replaced it with some sort of black box that has a circuit board inside and has 4 dip swtiches. There are no markings on the box to indicate what it is or a manufacturer. What the heck is this and why would someone do this?

I need to pull the codes. How can I do this now? Not looking forward to figuring out someone elses' wiring hack job.

I apologize if this is dumb question and if someone has asked this before.

thanks,

Hey,
West Raleigh. How will you be able to pull the codes if you don't have a port to plug into?

 

Did you look behind the ashtray?

 

Does anyone know where the service connector is supposed to be?

I did look behind the ashtray. Didn't see it.

 

90-up to 2002 you can short the scs connector

SCS connector? What is that and where might I find it?
Could you elaborate?

I know on some vehicles you can short two pins on the service connector and get the SES light to flash sequence for code numbers.

 

You got'er! That's exactly what the SCS is. It's the two wire service connector. You should be able to find it directly under your glove box. It is plugged into a blue or green holder.



There are two release tabs the one on the bottom you will be able to see from the floor of your car. The one on top of the holder is a bit harder to see but it is directly oposite to the one you can see. Depress these and then pull it out of the cross member toward the fire wall. Or you could just rip it out if that's more your style.......



and here are the two wires that you have to cross/short to get your CEL to flash the error code.



use a paper clip to cross the wires and turn the ignition on to the ACC/II position. And count the flashes. Fast ones followed by slow ones and then there is a pause and it repeats the flashes.

For example,

Flash..Flash..Flash..Flash (4) Flash........Flash........Flash (3)
ECU error Code 43 - Fault in ignition coil control circuit.

Hope that helps.

Here is a little tool I made to aid in the shorting process and it helps to reset the SCS light if and when it comes on as well. No need to keep pulling it out and plugging it back in......just turn it off and on...too easy.



Cheers...

Thanks Ghost! Now I'll have to find a code list. I imagine there are some on this site or the net somewhere.

 

Ok so I got
54,71,72,74 codes

CKF sensor problem. I did some searches.

Any suggestions? Simple as changing the sensor or could it be something else?

Car seems to run just fine.

Yes I would clear that code 54 first and go from there. I would suggest that you verify the operation of your Crankshaft speed fluctuation (CKF) sensor first. Just to make sure it's not a short in the wires or a bad contact somewhere.

Do you have a Haynes or Chilton manual? or
Does anyone have a link or info on the resistance check for the CKP sensor available?

I'll pick up a manual today.

Yes if some one could give me a value for CFK resistance check that'd be great.

How do I clear the codes? Disconnect the battery and wait? Is there anything else to disconnect? PCM fuse etc?

 

To check the CKF sensor first check for ground from pin 1 and ground from pin 3 of the sensor if there is continuity, then replace the ckf sensor. If the sensor checks out OK then move to checking for a open or shortin the wiring of the CKF circuit. Check the resistance between Pin c1 and c11(harness side) if there isn't 1.6-3.2k ohms then fix your open wire. Then check for ground from c1(harness side) to body ground, if there is conintuity fix the short. To clear the codes, just remove the "Back-Up" fuse (7.5amp) from the fuse panel under the hood.
