Message | The Ultimate Guide to Z32 Self-Diagnostics Whenever you get a Check Engine Light (CEL) or your car is acting funny, the first thing you should do is run codes. This guide will explain how to check, solve, and clear diagnostics codes on your Z32. US96 Z's need not apply. Shadow of mordor pc download free. Let's get to it! RUNNING CODES a. Pull back the carpet in front of the passenger seat from the top (closest to the dash). It's held in place with Velcro. b. Remove the four 10mm bolts holding the wooden ECU cover down, and remove the wooden cover. c. Turn the key to the 'ON' position (don't start it). 2. Consult Pins (LED and CEL): b. Using a paperclip, or small wire, jump the connection between pins 8 and 9 on the Consult connector, as shown below: c. Hold the jump for three seconds, then remove the jump. This is essentially the same as turning the potentiometer on the ECU. The easiest way of checking codes is using the Consult system. You can do this with a computer and a BlaZt Cable, for example. Software includes Conzult, Nissan Datascan, and several others. I'll show this using Nissan Datascan (since that's what I have). e. Click 'Self-Diagnostics.' If you used the third method, you've got your code, so you can skip down to the Code Index below to see what each one means and how to fix it. Otherwise, read on. READING CODES Now that you've gotten your car into diagnostics mode, you need to read the blinking lights to see what codes are displayed. The code is a two-digit number, represented by a series of long blinks for the first digit, immediately followed by a series of quick blinks for the second digit. Then a long pause, then the next code (or the same again if there's only one). For example, Code 34 (Detonation Sensor Circuit) would read like this: If you're reading off the CEL, it would blink the same way.
* May cause the CEL to illuminate under normal (Mode I) operating conditions. Most codes, as you can see, are triggered by a component CIRCUIT. A common misconception is that a code tells you a component is broken or malfunctioning. 99% of the time, the component is fine the code is thrown because the CIRCUIT (read: the wiring) has a problem, like an open (broken) connection or (more rarely) a short circuit. On rare occasions, a malfunctioning component CAN return voltage/ohms so abnormally high or low that the ECU throws a code, but not usually. Incidentally, when a component does fail, it usually doesn't throw a CEL. This is why a multimeter is your best friend—so you can ohm test every component in your engine bay! RESOLVING FAULTS: away any dirt, green corrosion, etc. Fill the connector with dielectric grease if you want (this will help prevent corrosion in the future). dental/mechanic's picks, or a small screwdriver and some needlenose pliers. Once you get the connector off, replace the spring clip—the connector will push back together without it, and this will prevent you from losing the spring. CODE 11: CRANK ANGLE SENSOR CIRCUIT. h. Check connector F23, which is the white connector by the Relay Box on the driver's side of the engine bay. Clean if necessary (these connectors seal a lot better than those on the CAS itself, so this usually isn't a big issue here). i. Clear codes and run them again. If the code persists, replace the Crank Angle Sensor. CODE 12: MAS AIR FLOW SENSOR CIRCUIT. c. Remove the spring clip and pull the connector to the MAF sensor. Replace the clip. g. Check connector F23, which is the white connector by the Relay Box on the driver's side of the engine bay. Clean if necessary (these connectors seal a lot better than those on the CAS itself, so this usually isn't a big issue here). h. Clear codes and run them again. If the code persists, replace the MAF sensor. CODE 13: ENGINE COOLANT TEMP SENSOR CIRCUIT CODE 14: VEHICLE SPEED SENSOR d. Unplug the connector to it (simply squeeze the locking tab and pull them apart). Check both sides for dirt and corrosion, and clean as necessary. CODE 21: IGNITION SIGNAL CIRCUIT:
c. There are two styles of PTU. The old-style is a large rectangular box, with a metal heatsink on the cover. If you have this kind, REPLACE IT. If you're in the US, you can get the dealership to replace it for free. If not, buy the PTU Service Campaign kit. This unit was recalled in ~92 for failing (ie dies when it gets hot). It was replaced with the new style, which had new connectors, so older cars had a subharness installed to adapt the connectors over. l. Check the connectors to each coilpack. These frequently break and don't seat properly, but can be easily replaced if this happens. Make sure all seat ok, and that there aren't any broken/shorted wires (shorted wires will melt a coilpack within ~30 seconds, so you'll know). o. Clear codes and run them again. If it persists, replace the Ignition Circuit Relay under the relay cover box with a known good relay. CODE 26: BOOST PRESSURE SENSOR CIRCUIT c. Disconnect the connector (squeeze the tab and pull DOWNWARDS). Check for corrosion and dirt, and clean as necessary. CODE 31: ECU MALFUNCTION CODE 32: EGR MALFUNCTION CODE 33: EXHAUST GAS SENSOR CIRCUIT (LEFT): CODE 34: DETONATION/KNOCK SENSOR CIRCUIT: g. If the code persists, check the ECU harness connector. CODE 35: EGR TEMP SENSOR CIRCUIT. CODE 42: FUEL TEMP SENSOR CIRCUIT: CODE 43: THROTTLE POSITION SENSOR CIRCUIT: c. Check the harness connector (the wire coming off the TPS). Clean as necessary, and run codes again. This connector likes to come unplugged after the connectors break over the years. CODE 45: FUEL INJECTOR LEAK CODE 51: FUEL INJECTOR CIRCUIT: e. Clear and run codes again. If it persists, consider replacing your wiring harness and ECU. CODE 53: EXHAUST GAS SENSOR CIRCUIT (RIGHT): Aws stencils omnigraffle.

These are icons of the various Amazon AWS services. It is current as of Jan. They're from SVG files and should scale easily. CODE 54: SIGNAL CIRCUIT FROM A/T TO TRANSMISSION CONTROL UNIT: CODE 55: ALL SIGNALS NORMAL.
Clearing codes is very simple, but MUST be done after you make any changes to see if you actually fixed anything. If you don't clear the codes, they'll hang around forever and show up every time you run codes. A common misconception is that disconnecting and reconnecting the battery will clear codes, but it won't—this simply clears the ECU's self-learn function, which is just a Base A/F tweak… you probably won't even notice. To clear codes, you basically enter and exit MODE II twice. There are three ways to do this: 2. Consult Pins (LED and CEL): c. Hold the jump for three seconds, then remove the jump. This is essentially the same as turning the potentiometer on the ECU. 3. Consult Diagnostics (computers!): e. Click 'Self-Diagnostics.' g. Click 'Reset ECU.' The program will send the clear signal to the ECU, and then check for codes again, and display them (if any). Hope this helps you troubleshoot your Z. Good luck! |

Blazt Cable And Software Setup
Blazt Cable And Software Engineer
A new web page is up showing the 4 different 300zx interface cables available. They are all used for reading from your cars ECU where the software reads the error codes and ECU data which is used to help diagnose and maintain your 300ZX.
There are 12 guages shown on the screen all running in real time, covering functions like RPM, temp, air/fuel ratio, ignition timing and throttle position.
You can use the self diagnosis section along with a wide range of active tests and data logging to monitor basic engine condition and any modifications you do.
Read why I bought the BlaZt 300ZX interface cable at 4-your.com/nissan
