Kerbsidemotors guide to how to read Pre 1994 Nissan fault codesIf you have a Nissan made between 1987 and 1994 this guide can help you. It shows you how to obtain fault code information and clear codes that will cause the management light to show and affect performance.This method will work on pretty much all Nissans made between 1986 and 1993 including Sunny/Pulsar (N13 models) Sunny ZX coupe (Can't remember the code!)Nissan Bluebird models (T12 and T72) the 200SX (S13 range) and 300ZX (Z31) UK cars. I have personally used this method on 200SX and 300ZX to great effect. If you want the procedure for Nissans after 1994 or pretty much any other Japanese car have a look at our other guides!Anyway, how do you do it? Its pretty easy really. Find the ECU! If it is a 200SX or 300ZX it is under the centre console. Take the thing right out so you can see the ECUStart the car and let it idle. If it doesn't start turn it over on the starter for 10 seconds or so.Turn the diagnostic switch fully clockwise (Small plain screwdriver) See the picture belowThe LED should flash 3 times. When it has turn it fully anti-clockwiseCheck the LEDs flash to confirmThe ECU will now flash the code. A red flash indicates 10 and a green flash indicates a single unit. For example, if the code was 23 the red LED would flash twice and the green LED would flash three times. Told you it was easy! The code will then repeat its self. Anyway, note the code down then switch the ignition off.Trouble code
