Pre 2005 NissanĀ Support

Nissan cars that have the grey 14pin Consult connector (you'll usually find it near the fusebox). These cars are usually built from year 1989 to 2000, including models such as 300ZX, Z32, Maxima, 240SX, S13, S14, Skyline, SR20DE, SR20DET, RB20, Altima, and Fairlady.

Nissan Consult is supported on most petrol powered (generally not diesel) Nissans built in the 1990s. If the car has the female consult port, it will most likely support consult. There are exceptions to the rule, however. Consult is only supported on the Nissan ECUs, so replacement ECUs like the PowerFC, etc, will not support it (remapped/daughterboards ECUs or those with piggybacks like SAFC should be fine). Also some late model cars from 1999 may have an OBDII port and a Consult port, but only retain the consult port it for ancilliary systems (like AT, AirCon, HICAS, etc) diagnostics, but the main ECU may be OBDII.


A 'consult interface' cable allows the connection of a Laptop/PC to a Consult capable car for diagnostics with Consult programs. The cables are not 'straight through', but have an electrical circuit inside the connector (not just a case of putting connectors on the ends of a cable).

Generally all Nissan Consult interface cables should work with all Consult software, although some circuit designs offer better compatibility with all vehicles.

Using the Cable

The steps for actually using the cable and software (see next section) are relatively simple:
  1. Plug one end into car's consult port. Often located near fuse box area
  2. Plug other end into laptop usb or serial port (or for Pocket PC, into null-modem adaptor or blaZt iPAQ cable)
  3. Ensure car is either ON (ignition on, but not running) or RUNNING. Consult port doesnt get power on ACC.
  4. Start software, select port (an onboard serial port is normally COM1, but for USB, see last step of driver install section below to find COM port number in device manager

Software Available

There are plenty of free consult software packages available, most notably:
  1. ECUTalk (notably for gauges/logging, also has trip meter gauges)
  2. OBD Scantech Nissan (active tests, fair amount of features)
  3. Calumsult (rom dumping, real-time graphs)
  4. Conzult Free (base idle mode, simple bar graphs)

ConZult, DDLreader v.15c
DDLreader v.16c
SRTalk v.1.0
ZCSetup v.2.0
ZTalk v.1.1
Nissan Data Scan v.1.4
