Bump Anyone? Sent from my SM-G900F using Tapatalk

Ah that would make sense, thought it would be wrong that the ecu would be supplying a switched 12v supply to the fan relay...... so this leaves me back at square one again for now Seems the wiring behind the dash holds the key to the dash light being illuminated constantly Sent from my...

Yeah I noticed the pinout diagram mentioned that pin 9 is the coolant fan relay pin , so the fact there was no power to the relay at all is correct and that the ECU has a switched earth to supply 12v to the coil? Sent from my SM-G900F using Tapatalk

Okay so another day hunting Throttle body changed so that cleared code 12 so all that is left is 13(coolant sensor error) Removed any air con related bits I could see right down to the relay and fuse, checked for any damaged wiring or plugs that may be left. All that was okay. Checked...

Also worth mentioning I guess is when I bought the car the check engine light was off but since investigating all of this stuff it started. Sent from my Nexus 7 using Tapatalk

Now I get ya, I'm going to have to have a look over the bay tomorrow for any residual wiring off the air con system which may be causing the error because I think it's fair to say I've ruled out pretty much everything else ha Sent from my SM-G900F using Tapatalk

Okay cleared codes by disconnecting the battery for 10 mins and pumped the brakes a few time to clear any charge that may be left. Did another fault code check and all that shows up now is 12 and 13 (MAF and temp sensor) I threw some power onto the fan also and it spun up freely. Went on the...

Again, gent as ever frank, i'll give it a go and report back because failing this, I really don't know. Looking very much like I'll need a new fan out of this anyway Sent from my SM-G900F using Tapatalk

How do I clear them? I must have missed that Sent from my SM-G900F using Tapatalk

Okay so, swapped all coolant sensors with different units again, checked for continuity between the plug and the temperature gauge as well as between the coolant sensor and the ECU and there are no breaks in the circuit. Is there something else I'm missing that would be causing the car to...

Also petrol flap release assembly, unless someone can suggest how to repair? Handbrake switch Sent from my SM-G900F using Tapatalk

How ye lads, bought a march that was in desperate need of TLC, didn't realise exactly how much until I got home. Need a few small odds and ends to get me started for cheapish money or even for postage costs if ye would be so kind. On a tight budget being a student and want to get this March...

Okay swapped out the single wire sensor for a known working sensor with no change. Shorted the wire like Frank said and gauge shot up. Thought maybe it was the plug for the sensor so chopped it off and fitted a new one, still nothing. Fault code read throws up code 13 so presume that relates...

Yeah I noticed that, i'll sus it out tomorrow when I have light to go back at it. Gearbox and driver mount weren't even threaded through , just half the way through the mounts. Proper lemon of a car Sent from my SM-G900F using Tapatalk

But the only thing this mentions is 1.0 auto to 1.3 gearbox, presumably for the longer ratios for the turbo build Sent from my SM-G900F using Tapatalk

Closer look it's a domestic engine in an import shell, has anyone pin outs for both March and micra engine looms? Have a feeling that's what's causing the issue, March ecu with micra engine and loom Sent from my SM-G900F using Tapatalk

Cool thanks again Frank, super helpful as always Sent from my SM-G900F using Tapatalk

Either keep an eye on for sale section, search the yahoo Japanese auctions using a search engine such as Jauce OR I think there was mention of someone making a replica but I may be wrong about the last one Sent from my SM-G900F using Tapatalk

Well that answered the question in my edit anyway, so just run a wire while connected to the block? Sent from my SM-G900F using Tapatalk

So just just a wire from one of terminals directly to the block to earth it, is it frank? Is there any way to tell which of the sensors is ecu or temp gauge? Sent from my SM-G900F using Tapatalk
