mustang Posted July 8, 2010 Share Posted July 8, 2010 As above, could anyone direct me to ABS and Trac ECU pin outs for my '93 J-spec 6spd TT? Quote Link to comment Share on other sites More sharing options...
CanisLupus Posted July 8, 2010 Share Posted July 8, 2010 (edited) In the Tech FAQ section theres a thread about the ECU Pinouts.

mustang Posted July 8, 2010 Author Share Posted July 8, 2010 Cheers CanisLupus but thats the main ecu, I was after ones for the ABS and Trac specifically. I did try searching, honest Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted July 12, 2010 Share Posted July 12, 2010 There's about 50 pages on fault code access and testing, you need the proper manual A lot of it needs an oscilloscope, too. Quote Link to comment Share on other sites More sharing options...
mustang Posted July 12, 2010 Author Share Posted July 12, 2010 Where can you get manuals from? I'd probably just get one now tbh. My car still has the ongoing ABS error codes so I'm gathering info for the garage that have it as they need it, they have an oscilloscope but haven't found a problem with any of the sensors so are starting to examine the wiring.

Chris Wilson Posted July 12, 2010 Share Posted July 12, 2010 Put a wanted ad up. One of our members now residing in Greece I think printed multiple sets of factory manuals, someone may have a set, or just the chassis and body manual that you need, for sale. It may even be available on line somewhere. Quote Link to comment Share on other sites More sharing options...
mustang Posted July 12, 2010 Author Share Posted July 12, 2010 Cheers Chris, I'll have a look around for it. Quote Link to comment Share on other sites More sharing options...
EMPEROR Posted August 10, 2011 Share Posted August 10, 2011 I know this is an old thread, but does anyone know if there is any difference between the pinout of nonVVTi/VVTi or UK/JSPEC ABS ECU? They definitely have different part numbers: JSPEC 89541‑14040 UK 89541‑14050 and the VVTi 89541‑14070 Although on the last one it says ('9305- ) which is pretty confusing... Can anyone tell me what the differences are? And I need the VVTi ABS ECU pinout if someone has it... Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 10, 2011 Share Posted August 10, 2011 From memory when I have fitted a VVTi with Racelogic traction control the pinout colour codes, at least, were different none VVTi models. Maybe Racelogic's web site will have wiring diagrams? I have never seen a factory Toyota manual for either Jap spec TT VVTi's or Jap spec pre VVTi models, but would love to...

mustang Posted August 11, 2011 Author Share Posted August 11, 2011 Emperor - It might be worth dropping Ian C a PM, he mentioned on another thread of mine he had found some PDFs about the VVTi's, not sure if they were to do with the ABS ECU though.

Ian C Posted August 12, 2011 Share Posted August 12, 2011 (edited) I don't have the VVTi ABS pinouts specifically, but I do know things changed with the facelift '96 Supra, and the VVTi one came 6 months after that so they might be the same. See if these wires fit the bill: Edit - outstanding fail of the built in table tool, what a waste of time. You get an unpleasant copy-and-paste to go through instead ABS wire - Colour - My harness colour - RLTC wire colour - Wheel (16 pin plug) A21-3 - RED - RED - RED - FR A21-8 - WHITE - PINK - YELLOW - FL (26 pin plug) A20-10 - BLUE - ORANGE - BLUE - RR A20-22 - PURPLE - PURPLE - GREEN - RL My findings: 12 pin plug (A): Pin - Colour - Function 2 - Black - FL gnd 3 - Red - FR +ve 8 - White - FL +ve 9 - Blue - FR gnd 26 pin plug (B): Pin - Colour - Function 9 - LGreen - RL gnd 10 - Blue - RR +ve 22 - Purple - RL +ve 23 - Pink - RR gnd 1500ohm between A2 and A8 1500ohm between A3 and A9 1020ohm between B9 and B22 1020ohm between B10 and B23 Edited August 12, 2011 by Ian C (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 12, 2011 Share Posted August 12, 2011 These resistance values, are they across the ABS sensor cables? Different resistance for front and rear sensors? Quote Link to comment Share on other sites More sharing options...
EMPEROR Posted August 12, 2011 Share Posted August 12, 2011 Thanks Ian! Will check and compare with mine the next few days and will write back. Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 14, 2011 Share Posted August 14, 2011 These resistance values, are they across the ABS sensor cables? Different resistance for front and rear sensors? I don't even know why I recorded them For whatever reason I measured them, it was done at the ECU end of the wiring loom, and probably to the GND pin or bodywork.

EMPEROR Posted October 14, 2011 Share Posted October 14, 2011 (edited) http://www.mkivsupra.net/vbb/showthread.php?252809-Facelift-ABS-ECUs-pinout Those are my findings so far, but still need to check few color codes. At least for the FACELIFT ABS Actuator w/ TRACTION PLUG B, the colors are a bit different or at least arranged in other order and the one without traction has 2 more wires on PLUG B (Green and Purple-Blue) that I don't know what they are about yet... Hope someone will help to fill in the gaps... Edited October 14, 2011 by EMPEROR (see edit history) Quote Link to comment Share on other sites More sharing options...
EMPEROR Posted October 25, 2011 Share Posted October 25, 2011 Some further investigation cleared one thing: Small brakes: NA (no Trac) and TT (Trac) use the same ABS ECU (89541-14060) and Actuator (44510‑14090) Big brakes: NA (no Trac) and TT (Trac) use the same ABS ECU (89541-14070) and Actuator (44510‑14100) Both small brakes and big brakes NA/TT with Traction use the same Deceleration Sensor - 89441‑20050 This applies only for facelift models. Didn't have the chance to check the pre-facelift Supras... So tables in the link on my last post will change a bit (hopefully soon enough).
