Nasiel som navod, ako si vyblikat diagnosticke kody aj bez Consult kabla, zatial som to neskusal, ale chystam sa ked bude cas :

Consult plug showing pins to connect for diagnosticsUsed on Nissans from 1989 until around 1998. (Note USA changed much earlier than this) 14 pin grey plastic plug in fuse box area below & to the right of the steering wheel.

[edit] Reading Fault codes

Turn the ignition key to the ON position but do not start. Orange "Check engine" light will illuminate along with oil pressure light etc.

To access error code retrieval mode use a small piece of wire, e.g. paperclip, to connect the bottom left two pins for approximately 2 seconds.

Disconnect wire.

After approximately 2 seconds "Check engine" light will start flashing fault codes. Long flashes are tens, short flashes are ones, e.g. 5 long flashes followed by 5 short flashes is code 55 = normal.

To check O2 sensor, start engine. Light ON=rich, OFF=lean.

Check that the check engine light blinks more than 5 times every 10 seconds at 2000 rpm in neutral when warm.

Alternative way for getting the fault code(s).

Take the kick panel off the centre tunnel beside your clutch foot & on the other side. You'll see your computer in the middle. Unbolt the computer from the car, there'll be enough cable to get it out the passenger side. Take the top off so you can see the 'diagnostic mode selector' trimpot rather than trying to turn it through the access hole. Turn the ignition switch on, but do not start the engine. Turn the pot fully clockwise. Wait at least 2 seconds, then turn pot fully counter clock-wise. The ECU is now in Diagnostics MODE II Read the codes flashing from the check engine light. Long flash is first digit, short flash is 2nd digit, see the codes below. To exit MODE II, turn pot fully clock-wise. Wait at least 2 seconds, then turn the potentiometer fully counter clock-wise, or... Start engine with the ECU in MODE II to enter MODE II - Heated Oxygen Sensor (O2) Monitor . The ECU is now monitoring the O2 sensor. Warm the engine to normal operating temperature, then run at 2000 rpm for 2 minutes. Check that the check engine light blinks more than 5 times every 10 seconds at 2000 rpm. NOTE: Light indicates signal from sensor to ecu. ON=rich, Off=lean. Blinking light means system is constantly adjusting between lean and rich which is normal. Any other indication would be abnormal and require further investigation. The switched on/off is 'closed loop', while a constant on or off is 'open loop' 11. To exit MODE II - Heated Oxygen Sensor Monitor, turn the potentiometer fully counter clock-wise and stop the engine.

[edit] Consult II / OBDII / NATS

Used on Nissans from around 1999 on (earlier in USA)

16 pin plug, each side of plug has a taper making the bottom longer than the top.

[edit] Reading Fault codes

Turn ignition key to the ON position & do not start the car.

Connect bottom left & bottom right pins of plug with a short piece of wire, e.g. paperclip

Disconnect after about 2 seconds.

This is how you reset the check engine light. No tools required!

In car ECM Diagnostics/ECM Reset procedure:

1) Sit in the driver's seat.

2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)

3) Fully depress and release the accelerator pedal five times in less than five seconds.

4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the MIL light flashes.

5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.

Long flashes (0.6 seconds) indicate the first digit of the code; count the blinks one through nine and write down the first digit. (Ten blinks indicates a zero.) The next three digits follow in turn in the same fashion except with faster blinks (0.3 second) and a 1.0-second pause between digits.

The ECM code repeats intself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard get-in-and-drive-the-car mode. You can look up the trouble codes in the ESM/FSM; there's a bunch of them. In the ESM, refer to page EC-639. Additionally, if you get four blinks of ten (0000), the ECM is indicating no malfunction.

You can clear the code (and the annoying MIL) by holding down the accelerator pedal for more than 10 seconds while in Diagnostic Test Mode II. When you release the pedal, the ECM erases the trouble code(s).
