What is NISSAN's Consult and how does it work ?

The NISSAN Consult is a hand held computerised diagnostic tool designed to communicate directly with the electronic control units (ECU's) in the vehicle.  Connection to ANY control unit is through a 'Diagnostic Data Link' (DDL) provided in the vehicle.

NISSAN Consult is designed to perform 3 basic functions (as follows):
-display the status of the input and output signals read at the control unit (ECU)
-read the conclusions of the electronic systems Self Diagnostics (error log) and display the name of the failed circuit.
-instructs the control unit to modify signals of certain sensors and actuators, thereby changing operating conditions to
confirm diagnosis. (not available for all systems)

What is conZult and how does it work ?

ConZult is a software application that was developed in Europe for the 90+ 300ZX (Z32), it is basically a PC-version of the very expensive Nissan consult. The ConZult software will enable you to monitor virtually every sensor in the car in real-time just like the Nissan Consult.  You will also be able to (temporarily) adjust fuel and timing maps, check solenoids, check and erase error-codes, log data and lots more.  The ConZult is an indispensable diagnostic tool, which can help you in problem determination.


What are the main differences between NISSAN consult and ConZult ?

The ConZult software will run on a PC or laptop, with data logging ability far exceeding Nissan's consult.  ConZult can export captured data to MS-Excel format for analysing, NIissan's consult cannot.  The export of captured data to logfiles enables you to compare data from different cars or runs.  ConZult is faster, more flexible to use and easier to work with.

What are conZults minimal (hardware) requirements ?

The software runs on almost any version of Microsoft Windows (9X/ME/NT/2000/XP)
minimal PC/Laptop hardware requirements are 133Mhz Pentium 1 processor and 16Mb RAM memory.
How is the ConZult connected?

Connection for the ConZult is via the same method as NISSAN consult and Techtom MDM-100, being the 'Diagnostic Data Link' (DDL) provided in the vehicle.  (in the 300ZX Z32 this port is located next to the hood release lever under the driver's side of the dashboard).

The ConZult interface is connected to the serial port of the laptop or PC.  Connecting the ConZult to a USB connector is possible with a USB to RS232 converter cable

Will the conZult be able to solve all my vehicles problems ?

In a word NO, I will try to keep this short ..... it seems often that references are made to 'consult' but most may not know what it actually is used for.  This may help you understand the so called myth of consult and it's uses.  In-fact I have listened to statements like " take your vehicle to NISSAN and they will plug-in consult and solve all your problems".  This is NOT true but to some it can seem true if your vehicle won't start due a failure of the Crank Angle Sensor (CAS) or Power Transistor Unit (PTU) and it's towed into a dealership.

If you own a workshop manual you will see references throughout to consult and it's method of use for a particular test. ConZult can save hours when looking for sensor related problems, although it only logs TOTAL SENSOR FAILURES, NOT parameters that may be outside operational tolerances this is left to the operator to determine.  That said one of conZults most beneficial uses is when a vehicle will not start or has a noticeable problem and the operator can quickly plug-in and check self diagnostic failures.   Although consult can aide immensely with problem determination it's NOT the be all and end all.   It's a great diagnostic tool, infact the best available for the 300ZX Z32 to aid/ help in problem determination, but like all diagnostic tools it's only a good as it's operator's knowledge and experience.

What kind of warranty comes with the ConZult?

If you experience a problem with either the software or cable interface promptly contact the dealer/ distributor you purchased conZult from and they should be able to help you out with advise.  The conZult interface cable is backed by a 3 month warranty on materials and workmanship. In the case of damage to the interface cable or connector they assessed on individual warranty case-by-case basis.  Technical support is available for the conZult software's operation and use ONLY, and does NOT extend to actual fault determination or rectification with customer's vehicles.

Does ConZult come with a manual of some type ?

The software comes with a comprehensive manual in PDF format written by Steven Lipke.

Is the conZult able to be constantly attached to the car or should it only be used at service times or when problems occur ?

Yes you can leave the conZult attached to your vehicle as you require.  The software enables you to monitor virtually every sensor in the car in real-time and you will also be able to (temporarily) adjust fuel and timing maps, check solenoids, check and erase error-codes, log data, etc.  Although it is NOT recommended to make any active changes to the vehicle whilst in motion UNLESS you are FULLY AWARE of exactly what these changes will have on the engine and or it's associated systems.   Failure to fully understand the effects could lead to permanent engine damage & or failure, this is particularly relative to the fuel mixture reduction and or igniting timing advance.

Will the Conzult software be available for PDA's/Palmtops ?

Currently there is a working, but stripped version of the conzult for the Psion Workabout/3c handhelds.  We are looking into the possibilities to port (parts of) the software to WindowsCE or Linux, so the software can be used with a PDA that runs winCE/Linux.  If it appears to be possible to port the software and it will come available, it will be freely available to those
that have officially bought the interface from our distributors.

Can the Conzult be used on other Nissan vehicles ?

The Conzult-SX was developed for 4 cylinder Nissans that have a DDL connector.  Thus far, it works successfully on the  following models: RNN14, N14, B13, N15 and S14.  Prerequisite is that the car needs to have a DDL connector.

For Skyline owners: the ConZult has been tested on several Skyline models but unfortunately our hardware doesn't work on these cars.  We are looking into possibilities to adapt the hardware (and software), to make it work..  A conZult version for other Nissans needs to be looked at on a model to model basis.  Some of the features of the ConZult for the Z32 might work, but it's not supported at this time.

How do I get the latest software updates ?

New software updates will only be available free to registered ConZult users.  All ConZults come with a registration card that must be completed in order to receive updates.
