Hi all Names Neil. First post in Celica forum. Just acquired a ST184 from a friend who just wanted rid of it. Weighing up my options atm. Motor was cooked and is unsalvageable. Not too worried as there are plenty of motors around.My main concern is how easy it is to fit the Camry version of the 5SFE engine to the Celica as they seem to be easier to find. Or maybe a jap import? Main priority is to get her on the road first then see where I go from there. Any thoughts or input welcome. Not after heaps of power just reliability.(too old been there done that)

Ok a final update for all. The problem IS the two mini relays on the BCM board located at the rear top of the Fuse Box under the cover marked at least on our Camry With the word LOW on the label. This module controls the Door Lock/Unlock function and also the Interior Light functions. Am presuming that with the higher spec models this board has more functions. The relays can be purchased online and will soon be getting a pair, These are your lock/unlock relays and have found out by experiment that they do not stop the car from being started/driven. Board also controls the alarm functions such as the horn beeps and light flashers you get when you arm/disarm the system.Repair is not for anyone that is not confident with small component soldering. Minimum tools you will need are a soldering station ( no gas axe job here ) and a solder sucker or similar. God knows the price of this board from Toyota but I can imagine the drama of fitting a new one with probably re learning or replacement of remotes. Will post up a full pictorial when I do it in a couple of weeks.

Ok time to give an update. The Body Control unit is built into the fusebox. Access is via four small phillips head screws after removing the three 10mm nuts that hold the fusebox in place. The ECU circuit board simply wiggles out of its multi connector. Have figured out that mine at least is faulty in that whilst the cover is off the system works perfectly however as soon as I put it all back together and tighten everything up it goes phut again. Am thinking of replacing the mini relays shortly to see if that finally cures it. Losing daylight here atm but am going to pull the fusebox out again tomorrow and have another go at it. Will post up my results tomorrow afternoon. If all else fails to fix this am going to wire in an aftermarket door module and do away with the factory system. Oh and before anyone says it wont work I can assure you it will. The door control ECU whilst surface mount is not canbus as such but will require the rewiring of the door motors and isolation of them from the car system. The only functions I may lose are the interior light and ignition key illumination.

My partners Sportivo has been doing exactly the same thing. Being an electronics tinkerer I decided to try and solve this problem. Checked the following: Door switches Boot switch Bonnet switch All clean and making good contact so under the dash was next port of call looking for the ECU as I have had this problem with the Statesman that I used to own. Correct me someone please if I am wrong but the ECU is integrated into the fusebox on the 2003 Camry. Could hear the click of a mini relay within whilst toggling the Lock/Unlock switch on the drivers door however it was only clicking whilst hitting unlock. Nothing ventured nothing gained so gave it a sharp rap on the case with the screwdriver handle and voila full function has returned at least for the moment. Without removing and disassembling the ecu case for a look see my guess is that there are some dry solder joints within. The permanent solution? Replace the ecu however I can only presume that like most other late model cars that would also require new keys and transponders.

Good day all. Names Neil and I live in Morwell Vic. Drive a 2004 Prado and my partner Nikki has a 2003 Camry Sportivo. Hope to catch you round the forums. Cheers.
