Hi Speedy I have a 1996 3rd gen surf with the same flashing orange and green lights as you video. I checked the rear switch on the transfer case actuator (TCA) seemed a bit suspect but cleaned and sprayed with. Contact cleaner and seem ok now I will try and get a new switch. The switch in front of that on the TCA was ok and checked the fuse and disconnect and reconnect the battery but still the same fault?

I’m in Buckinghamshire uk struggling to get any information thr manual from Roughtrack doses give me any information in the 4wd for mine and I don’t think the wiring diagram in the manual is the right on.
Any help is very much appreciate or if someone can recommend somewhere in my part of the uk I would happy pay.
Thanks in advance Dave

Are you getting any 4WD engagement while the lights are flashing? Or is it staying in 2WD and flashlight?

Sorry I haven’t got back sooner I’m dyslexic and struggle with forums and all the typing and stuff and been busy trying to sort the issue out.
Since posting I’ve managed to track down another transfer box activator Strip it clean it test it make sure it’s okay fitted it but all it seemed to do was drive part the way in and leave me with flashing Centre diff and four wheels.
I removed it again checked it refitted it making sure it was in the two wheel drive position and everything was okay no lights in two wheel drive position as soon as I press the button for four-wheel-drive I just got all flashing lights I then manually drove the activator to on road four-wheel-drive position and everything was okay with just for green lights on for the wheels in the on road four-wheel-drive position but when depressed The button then I got all flashing lights again. With the activator removed I selected four-wheel-drive position by pushing the shaft in with moll grips and though it struggled to go in I think that was just because it was in a stationary position I don’t think there’s anything wrong with the transfer box. There are three switches on the transfer box which I need to test but due to the bad access and not being able to get anything that fits them to go on I’ve not managed to remove them yet to test so this is my next task just to check that the position switches on the transfer box are okay. I remove the ECU from inside the passenger foot well took it out of his packaging and give it a close examination there are no signs of any damage corrosion or capacitor damage so I don’t think there’s anything wrong with the ECU. Once I have checked the three switches on the transfer box I am at a bit of a loss as to what to do next. I will make sure I keep an eye on the forum and pick up any responses straight away this time and apologise for not doing that last time. If I’ve got a garage to plug in for a diagnostics I don’t know if the diagnostic system would produce any errors or any information that might help me pinpoint and resolve this problem.
Any help really well be appreciated

Regards Dave
