Can anyone verify if I have a MEFI 2,3, or 4? I have a 98 Malibu Sunsetter VLX with monsoon 320 (EFI).also, i found this at another forum, and want to confirm that it will work for our bu's. Thanks!DIY Code ReaderMaterials needed:One 12volt resistor type LED light - Standard LED nothing special make sure it is a 12 VOLTOne small paper clip cut in halfThat’s it!This home made code tool works every bit as well as the one I paid $50.00 for. It will work on most 1993 to 2000 marine EFI systems with the ten pin Data Link Connector. This includes MerCruiser, Volvo, Crusader, PCM, Indmar, and a few others.How to hook it up:1) Ignition key “OFF”2) Remove the cap from the Data Link Connector (DLC)3) Slide the LED into the female terminals of position E and F on the DLC, making sure that the positive side goes into terminal F and the negative side into terminal E.
No damage will occur if you get it backwards, it just won't work.4) Turn the ignition key to the “ON” position. The LED should come on steady.5) Insert the half paper clip into terminals A and B – This puts the engine in “Service Mode” and codes will begin to flash on the LED.
MerCruiser Scan Tool. For GM-Delphi MEFI-1 thru MEFI-4. This pocket size tester serves as both an EFI Problem Indicator and a Spark Timing service tool. It is the perfect tool for low volume marine repair shops that troubleshoot a small number of EFI systems a year. CodeMate allows fault codes to be read and allows base spark advance to be.

On 1996 and earlier engines you may hear the fuel pump come on. If not you should be able to hear the Idle Air Control (IAC) motor move. Use care in this step, do not insert in the wrong terminals or ECM damage could result! Look closely, the terminals are clearly marked.6) Read codes by observing LED flashs.
If the self diagnostic system is working it will flash code 12 – one flash, pause, two flashes, long pause – it will repeat three times. If other codes are present they will flash in order of lowest to highest. Continue to read codes until the code 12 sequence is repeated.You can also be clear codes (by moving the throttle to 100% and back) and set base timing while in Service Mode.If you want to make a plug-in Service module use the following linkThe connector is a Packard 'Mertri-Pack' 150 series sealed 10 pin male connector.
In addition to the connector body you will need the TPA (grey thing that clips to the top), terminals, seals, and (optional) plugs.Info on Metri-pack connectors.

Still cannot verify if the code reader trick will work, but I did spend some time in the engine room investigating today. The terminals on the assembly line diagnostic connector (ALDC) that royeh32 mentions appear to be the terminals to make this work. I already knew that connecting terminal A to B on the ALDC would put the ECM into diagnostic test mode (with key on) or service mode (with engine running). So what I really looked into was terminal E and F. Terminal F on the ALDC is a +12 volt terminal coming directly from a fused wire going to the battery.
Terminal E on the ALDC goes to pin J1-27 on the ECM via a brown/white wire. Indmar refers to this pin as the 'CE' on its pinout diagrams.
I am guessing that CE stands for either code enable or code emitter but I will try to verify this.edit; Let me add that the other two wires going from the ALDC to the ECM are designated as the serial data and the master/slave wires. These wire could not carry an on/off code. Edited October 18, 2008 by electricjohn.
Hey Y'all, what's shakin?So, WyoTech has been shoving Snap-On down my throat for 11 months now, and the only things I really like are the ETHOS and VERUS. Wait, is it the VERUS? The top of the line thing, above the MODIS.ANYWAYS, what's the difference between a code reader and a scan tool? Is the ETHOS really worth the $1200 price tag? I don't want to pay for the Snap-On name, but that ETHOS is sick.So, I'm looking for an entry-level technician's scan tool/code reader and I have no idea what to look for or buy because the school says: 'Buy the ETHOS. If you don't want that, buy a MODIS.'
Problem is, NOBODY even comes close to the same ballpark as the ETHOS. It's really a kick-@$$ tool. I want PID and Freeze Frame data. I want to read and clear codes for any PCM, ECM, ECU, TCM, ABS, BCM, CCM, and any other Controller Modules I might be forgetting.I think PID is sick because you can see whether the TCC is locked up, and compare that to MAF, MAP, TPS, and HO2S readings to aid in diagnosis. Plus, it's fun to open the throttle plate and watch the STFT's go haywire.I aim to work at GM as soon as I can get in their doors. I know they have the Tech II, but have Y'all seen the MDI?! It's all wireless!
I shadowed a guy at GM here, and he hooked that thing up WIRELESSLY to the DLC, WIRELESS to his personall laptop that sits on his tool box, then he showed me how he can pull all of the info off of the MDI, onto his computer, have the big screen, and compare it side by side with the actual GM service information, rather than that third party stuff all in an effort to make an easy and correct diagnosis.Then, he unplugged is laptop from everything, and said: 'follow me'. He walks out and sits down next to the customer in the lobby, and they can both look at the data on his laptop. The customer asked a question, and the Tech said: 'Let me see.' He goes back to other data from the tool and asks the tool to show him this, that, and the other thing, compares it to GM's Service Info, and answers the customer's question using the tool and his laptop to teach the customer what was wrong with the vehicle. How sweet is that?!So guys, who makes what, and what's it gonna do to my bank account to buy it? I know I won't NEED it if I work at a dealership, but when the clowns in the sales dept. Make a trade for an 04 Mustang that has a P0305 code, I would like to know that I have access to a tool that WILL tell me: 'Hey dummy, you got a miss-fire, Cylinder 5.
Try testing the ignition and fuel delivery systems.' And not just 'P0300, Miss-fire, perform further tests to determine which Cylinder(s).' Thanks, gents. Must be nice to be made out of money and have a MODIS.
I heard they recently shut down production and are only planning 2-3 years of updates before completely phasing it out in favor of the Verus, Vantage, and whatever else.I forgot the name, but MATCO has a nice competitive tool that's right in with MODIS. I simply won't pay through my nose to buy the Snappy name.So what exactly is the difference between a 'code reader' and a 'scanner'? Is a reader simply that and nothing more?Thanks again, guys. I'm sure your school has some type of purchase tool agreement with Snap-On, alot of schools do.
I guess what scan tool you buy depends upon what you can afford and what you want to do with it. I can only speak from personal experience.
I have a Modis and I like it but I feel like it's way over priced. I bought it back when it first came out and was the hottest thing.
Before that I had a Snap-On 2500 'red brick' and the Snap-On Vantage meter. I still have those two along with the Modis and they're just about indestructible. I've dropped the red brick numerous times left it near a hot engine, you name it, never had a problem with it. The Modis is good, especially if you learn how to use all that it has to offer. I really like having the 4 channel lab scope.
But what ever you buy learning how to use it properly is the key because it's just a tool and it just provides the information. It's up to you to determine how to use it. Good luck.Please or to join the conversation. Quoted From Chevypower:I want Jennifer Aniston in my bed.

But like the Verus, that just ain't gonna happen.So, who do I buy from for everyday professional use? MAC, MATCO, or Cornwell? F. the Snap-On prices.
I refuse to over pay for a tool just because every Mechanic and his brother owns them.And I want a real scanner, not a Modis/Verus/Solus type of tool. That's a freakin NASA rocket ship compressed into hand held. No, I'm not ready for full on diagnostic tools yet. Just a dang good scanner.That made me laugh!Did you ever look at the Actron C9190?Its a pretty decent scan tool for the price and it is what i use for personal use. Granted its not bi-directional but it shows PID data that would be a nice start for a newer tech to learn from.I think theres also another thread around here with scan tool info and what to buy as well. Quoted From Trcustoms719:Yeah i want a Verus too.I might actually look into a used Vantage though.The vantage is a piece of garbage unless you do not have a lab-scope at all. The processor is weak and is super slow.
