OBII Code Reader EZ-Scan 4000

This is one of the OBII Code readers supplied by Gendan Direct. This EZ-Scan 4000 code reader will help you read error codes from the Esprits V8 engine management system and reset the engine check light once the error has been dealt with. It will also allow live data feeds and you can save and download this information to your PC. This is a quick guide on how the 4000 works and how to use the reader on an Esprit V8. For more info on OBII readers and more details on the EZ-Scan 4000's specification, see the OBII Guide under maintenance.

You can purchase the EZ-Scan 4000 here and for details of the 5% discount available to Club LEW members, see here

The EZ-Scan 4000 Code Reader was delivered next day via courier. It comes in its own plastic carrying case, including the reader, OBDII cable, PC cable, Software, batteries (4xAA) and user manual.

  

The reader has a large LCD display and plenty of features. Now for connecting it to an Esprit V8. We used a 1999 Sport 350 to test the reader on. This equipment should work on all V8 Esprits except the early 1996 model, which uses a different system. We used the connection under the passenger seat dash to connect our reader to. You'll probably need to get into the 'Lotus Position' to find the connector (see right). The connector can be pushed right up under the dash and may need some searching to find.

  

This is the connector you are looking for (left). There was also a ALDL connector attached on the same loop on the Esprit we used, so make sure you use the correct one. Now simple connect the OBDII connector to the correct end of the 3100 readers cable. This is how your connector should look once connected (centre).

  

You can now attached the other end to the reader. You are now ready to go (right).

   

The EZ-Scan 4000 is more complex than the easier to use 3100. So I would suggest you refer to the user manual to get the best from all the features. We have purchased one of these for future use and will report more about it's features in the future. For now we started the engine and turned on the scanner. After a few seconds the scanner was feeding live data straight from the Esprits Engine management computer. Including Speed, RPM, Throttle position, Intake Air Temperature, Oxygen Sensor info and much more.

Fortunately the V8 we tested had no fault codes present and was in good health. If the reader brings up any codes, all you need to do is look up them up in the manual. The manual holds all the generic codes for OBDII. For Lotus specific codes you'll need to refer to the V8 manual. These codes should be made available shortly for those without a workshop manual.

Verdict

This code reader is for those who wish to take a more detailed look at how their Esprit is running. It still allows you to read the fault codes and reset the check warning light, but also allows you to read all the data that the ECU records and see, even while driving the car. You can then download this information to your pc with the software provided and plot performance graphs to evaluate the performance of your engines as with the simple OBDII Cable and FreeScan. At double the price of the 3100 it's got much more power, but will you use it?

The device can also save you money! You'll be able to read the codes and find out the problems your V8 is having without having to trek to the nearest Lotus Dealer. False alarms can be spotted and simple fixes can be performed without the need of a dealer. More serious problems can be dealt with quicker and more safely and reduce the dealer time on your Esprit, saving you money. You can also check over the engine if you think it's not running as well as it should. Why wouldn't you want one? 

Remember this will work on some post 1997 vehicles and most post 2001 vehicles, so you can use it on the 'other' car!
