Pixelfill Posted January 15, 2012 Share Posted January 15, 2012 replacement ECU arrived from Keron, and after tearing my arms apart replacing the ECU through the glovebox (there has to be an easier way) it has fixed the problem, Central locking now works perfectly.

mwilkinson Posted January 15, 2012 Share Posted January 15, 2012 Glad it's all working again. If you slide the pcb out if the old door ecu you will probably find the circuits are coroded. This is what I found on mine. Quote Link to comment Share on other sites More sharing options...

Pixelfill Posted February 2, 2012 Share Posted February 2, 2012 Out of interest, does this fault prevent the internal switch working too? Mine has started central locking but not central opening, from either the fob, or the internal switch. Or does this not sound like the same fault? replacement ECU arrived from Keron, and after tearing my arms apart replacing the ECU through the glovebox (there has to be an easier way) it has fixed the problem, Central locking now works perfectly. Mike Worst luck ever. Looks like the replacement ECU has now suffered from the cold weather. Central Locking is not working, but central unlocking is, the reverse of the old box - how easy is it to make one working unit out of the two I have Mike Quote Link to comment Share on other sites More sharing options...

Samurai 20V Posted February 10, 2012 Share Posted February 10, 2012 Been doing some research on this.. The 1996 and earlier version is the blue one, it has been discontinued.. The pic is from a Yahoo Auction advert for a 1994 RZ.. The 1997 and later is the red one, confirmed by the Yahoo Ad for the following unit.. I checked Toyodiy and it confirms my findings with the part numbers.. So it seems the one to get is the red one.. Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted February 10, 2012 Share Posted February 10, 2012 ah great that's worth noting - however both my failures have been "red tops", and my car is a 1996 pre-facelift so assumed the red was the older model. It's also interesting that the red part number is lower than the blue one. thanks for sharing. Mike Quote Link to comment Share on other sites More sharing options...

mwilkinson Posted February 11, 2012 Share Posted February 11, 2012 My car is a J-Spec 1995 RZ. It had a red door control module fitted. I replaced mine with a blue one from a facelift car. I have also taken a red one out of a 1994 UK spec. Thus I always assumed it was the other way round! Quote Link to comment Share on other sites More sharing options...

I have also taken a red one out of a 1994 UK spec. Thus I always assumed it was the other way round! Now I am confused... I think I will have to check what is in my car first before buying one.. Does it matter if the car is an RZ or SZ, I would think not? Quote Link to comment Share on other sites More sharing options...
Calzo21 Posted December 10, 2012 Share Posted December 10, 2012 Restarting the thread But this is a good find saves me starting a thread But this has very recently happened with my facelift '97 j spec TT And it's all started since the the cold and frost came, couldn't understand why it unlocks fine but the fob doesn't work to lock or key either, and its tempremental it works then it doesnt. so il give driving on full blast a shot if not il have a look up at these little boxes Cheers guys Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted December 11, 2012 Share Posted December 11, 2012 Yes these issues crop up every year and the control module is often the culprit. I think they suffer from dry solder. I might see if Si can inspect a duff unit to see if there is anything obvious that can be repaired. Seems to be a common fault and at the rate of failures seen over recent years, spare control modules may be like finding rocking horse poo!! - - - Updated - - - Yes these issues crop up every year and the control module is often the culprit.

listy Posted December 20, 2012 Share Posted December 20, 2012 POW! And another one bites the dust! Looks like I'm in the same boat had to climb through the boot to unlock the car this morning! The alarm arms and disarms with the fob, but the car won't lock or unlock After reading this, guessing its the control box. Anyone tell me how much these cost?

Pixelfill Posted December 20, 2012 Share Posted December 20, 2012 My advice is don't try Toyota, unless you fancy a laugh !! Seriously ... very expensive. I think I paid around £25 for each of my replacements 2nd hand, but be advised that they may well suffer the same fault sooner or later. You should still be able to get into the car with the key though. Mike Quote Link to comment Share on other sites More sharing options...
listy Posted December 20, 2012 Share Posted December 20, 2012 (edited) For some reason, never thought of trying the key in the door lol been so used to RCL lol It does work though, so no major drama. Just winds me up knowing something isn't right with the car. I've just spoken to Keron and it'll be £36 delivered. Where did you get yours from?

Guest columbo Posted January 5, 2013 Share Posted January 5, 2013 i got a red one from keron just before christmas...fitting it today and i will let you all know how i get on. btw , yeah it was £38 from keron and he had it over to me in Ireland in a day or 2, ( thanks mate ) Quote Link to comment Share on other sites More sharing options...
Guigsy Posted January 5, 2013 Share Posted January 5, 2013 Mine still works but it doesn't clunk like it used to. It's like the mechanism is stiff somehow. Happened after the car was in the bodyshop so guess its somehow got covered in dust. Quote Link to comment Share on other sites More sharing options...
Supra Gaz Posted January 5, 2013 Share Posted January 5, 2013 I have spent the last weekend looking over my mates central locking, he can un-lock by the alarm fob, but only lock if he pushes the catch next to the handle on the drivers door then climbs out through the passenger door and locks it on that door with the key. The button to lock both doors on the drivers door doesnt work either, when he tried to lock with the fob, key in drivers door (which has never worked for some reason) or button on the inside, he doesnt get a clump noise to suggest the system is even trying to lock. We considered the control unit, so I put mine (pre-facelift red unit) in from my car which works, it didn't work in his, so we took the drivers door card off and had a look, all looks ok, a little damp so WD40'd it quite thoroughly, still no joy. Any ideas folks, he is loosing the love and I am out of ideas. Quote Link to comment Share on other sites More sharing options...
