Accessories for the Snap-on MODIS 

Test Drive Test Leads
The MODIS is great tool but it's lab scope test leads are too short for test drives. Plus, when using multiple channels ground stacking becomes a problem. The ST3 Test Lead Kit for Snap-on MODIS solves these problems.

Tech Tip from Ferret Instruments
COP and the Ferret 953 Secondary Ignition Adapter

As COP type ignition systems become more popular, we are getting more and more tech support calls asking how to capture secondary ignition parade patterns from COP systems using our Secondary Ignition Adapter. 

The Expensive Option: 
Spend a bunch of your hard earned dollars buying coil adapters for various COP systems.

The Less Expensive Option:
Techs in the field have been using the following method for quite some time with very good results on most systems.  Hook up the Ferret 953 Secondary Ignition Adapter as you would on a DIS system, one capacitive lead for each cylinder. Tape a lead to the body of each coil with aluminum tape which you can purchase at your local hardware store.

Set both polarity switches on the module to negative and plug the leads into the module. No particular order is needed. Be sure to connect the ground lead to a good engine ground. Connect the inductive #1 cylinder pickup around the coil primary lead for #1 cylinder. If the primary lead is inaccessible, you may just sit the pickup against the #1 coil. In this case, be sure the jaws of the pickup are closed. Secure with aluminum tape if necessary to maintain its position. Note: if the pattern is inverted, just switch the polarity switches to Positive.

Instead of using aluminum tape you can fashion adapters from foil that been folded so it is at least 4 thicknesses and press around the coil until a good fit is achieved. Roll another piece of foil so it is about 5/16" in diameter and staple it to the main piece leaving enough of a loop to clip the capacitive leads to it. Once you have a good fit you may use epoxy to protect it for future use.

The 1, 2 and 3 of Mode $06

Two new books by John Forro of AST Training help take the mystery out of Mode $06 diagnostics.  Mode $06 data can provide the following information:

#1 Which monitor is going to fail a test or has it already failed a test.  This is a lot like pending codes or the General Motors version called failure records.  This in itself is a great time saver!  Imagine not having to drive those long drive cycles anymore to see if a monitor is going to fail a test.  This feature allows us to see if the PCM has run the first of the required two tests for a non-continuous monitor and see if it has passed or failed that test

#2 Which component/parameter is causing the failure to occur.  Hmm, imagine how cool this would be on say a P0440 trouble code.

#3 The pass/fail criteria for the component that has been flagged as being faulty.  Wow, what a time saver this is!  Imagine not having to look for specifications.  and also being able to be very confident that once the repair has been made that it should pass the monitor the next time the PCM runs the test.  

Compatible scan tools typically display Mode $06 data in hexadecimal or decimal code, a 16-digit system commonly used in the math, science and computer industries. To make this data useful for automotive diagnosis you must convert it using the Hex or Dec functions on your calculator.  Wouldn't it be easier if these conversions were listed for you in a quick reference?

These two new books provide those Mode $06 conversions!  

Each book provides an introduction to Mode $06, codes for each manufacturer along with the highly sought after Mode $06 TID and CID descriptors. Years of research at your fingertips!
