The check engine light will then begin to flash stored fault codes. To install this engine I need the wiring diagram.

300zx ecu diagnostics code#

How do you find the fault code on a Nissan? Software includes Conzult, Nissan Datascan, and several others. You can do this with a computer and a BlaZt Cable, for example. Consult Diagnostics (computers!): The easiest way of checking codes is using the Consult system. DonвЂ™t over-turn it, it doesnвЂ™t take much effort to turn at all, and the light will turn off. Turn the potentiometer on the ECU all the way to the right (clockwise). Turn the key to the вЂњONвЂќ position (donвЂ™t start it). Remove the four 10mm bolts holding the wooden ECU cover down, and remove the wooden cover. How to turn off the ECU on a Nissan 300ZX? 54: Signal Circuit from A/T to Transmission Controller Unit. All the same with no long start flash = Battery low, been disconnected, or control unit has just been reconnected.For example, Code 34 (Detonation Sensor Circuit) would read like this: If youвЂ™re reading off the CEL, it would blink the same way.10th flash longer than others = Line pressure solenoid circuit is shorted or disconnected.9th flash longer than others = Engine revolution signal circuit is shorted or disconnected.8th flash longer than others = Fluid temperature sensor is disconnected or A/T control unit power source circuit is damaged.7th flash longer than others = Lock-up solenoid circuit is shorted or disconnected.6th flash longer than others = Overrun clutch solenoid circuit is shorted or disconnected.5th flash longer than others = Shift solenoid 'B' circuit is shorted or disconnected.4th flash longer than others = Shift solenoid 'A' circuit is shorted or disconnected.3rd flash longer than others = Throttle sensor circuit is shorted or disconnected.2nd flash longer than others = Speed sensor circuit is shorted or disconnected.1st flash longer than others = Revolution sensor is shorted or disconnected.All 10 flashes the same = No error codes detected.To display a code, one of the 10 short flashes will be longer in duration than the others. All 10 flashes the same duration indicates no problems. The first long flash signifies the start of the code sequence, followed by 10 short flashes. Fully depress accelerator pedal, then release it.Wait 2 seconds, then move the shifter to '2.'.Wait 2 seconds, then switch the Ignition switch ON.Switch the transmission to D (Drive), either by using the brake pedal or the release switch (pictured below).The A/T Light should go out after about 2 seconds. Ensure the engine is at operating temperature, in P (Park) with the Overdrive switch on.Just like one would do for your ECU, the Automatic Transmission Control Unit (colloquially called the Auto ECU) can run self-diagnostics to indicate faults. If your transmission is shifting hard, early, late, or just acting funny, a good starting point is to run codes. The Z32's automatic transmission is a pretty good one for it's era, but it's not without faults.
