Engine Light

[Butcher]

Engine light came on today. No apparent problems with the car. Just the light of ever-lasting uncertainty in the dash. 

 

How do I check for fault codes and stuff? Had a quick look but I can't see any guides on here.

In the passenger footwell up behind the glovebox there's two connectors... A 2 pin and 5 pin. 

If you bridge the 2 pin one with a paperclip or something, then turn the ignition on, the light will flash to give you the code.

There is some info on here somewhere... I'll have a spy

Seems to have gone awol... It's mentioned here though with the codes...

Cheers Broon. I think that's one of the threads I looked at before, just went to a dead link. 

 

Anyway, found this one, which looks just the ticket.

 

 

Shall give it a go tomorrow.

Should be able to get the code with that how to no probs mate. I'll update that broken link too with the fault codes when I get a chance too, thanks for letting us know.

Here's the codes mate. Found them in an old topic in the Electrical section.

You can jump the 2 wires on your diagnostic plug. Then read the number of flashes you get from the light. A long flash reads as a count of 10. short is a count of 1. so 3 long and 2 short would be 32. Then you can look up what code it is. That will tell you what part needs replacing.

This is the list of error codes I have for the entire Honda range. Long flashes = tens, and short flashes = single units.
