Purchasing Advice - Hold Light Flashing

[AndyBongo]

I'm looking at a local Bongo, 1997 2.5D Automatic 4WD.
It seems to drive fine and not being restricted to 'Limp Mode' however the Hold Light is flashing.
As its not in limp mode can I assume that this is maybe an electrical connection fault? I believe it might also be a fault with the device fitted to convert KM's into MPH.
Would you advise just walking away from the purchase, but then any future vehicle bought could develop the fault, or buy it at a cheaper price and attempt to problem solve it.
Any advice greatly appreciated. This will be my first Bongo

THe flashing hold light merely is the Transmission Control Module part of the ECU saying it has an error report, what the error is needs to be read out from the diagnostic connector, it can be a simple problem to a rather more complex one, but without reading out the actual error code itself then all you know is its reporting something!
This site gives you advice on reading the error codes http://www.philmcfadden.co.uk/MazdaDiagnosticBox.htm
there is also a Factsheet in the members area with more info https://igmaynard.co.uk/download/diagnostics.pdf you need to be a club member to access from the Members Area.

All looks good, I'll give it a try. Only thing is what's the led mentioned? Is this on the vehicle, or one I've to put together on wire connection?

I've read elsewhere that connecting TAT & GND is required, but you can then read the code from the flashing of the Hold Light, and no need to put an LED connection across B+ & FAT pins. Is this correct?

It depends on the age of the vehicle/ECU later versions flashed the Hold light with the error count so don't need the extra LED connected to see the flashes.

So true , but normally you dont buy the vehicle with the faults already there, its cheaper waiting for them to occur ,if ever.
