BrandonspecB Posted March 2, 2021 Share Posted March 2, 2021 Interesting build! Each wheel speed signal goes to the ABS unit then vehicle speed is sent out over the CAN to the other modules. Link to comment Share on other sites More sharing options...
GEE-OTTO Posted March 2, 2021 Share Posted March 2, 2021 Kudos to you sir. The tub job cleans up the front! you must enjoy the challenge of all this which most folks would never attempt. If you merged harness, per your earlier post did that harness have a connection to the ABS? Link to comment Share on other sites More sharing options...
Deeregamer Posted March 2, 2021 Author Share Posted March 2, 2021 Interesting build! Each wheel speed signal goes to the ABS unit then vehicle speed is sent out over the CAN to the other modules. So if thats the case couldn't I simply plug the board half of the abs pump back into the passenger side harness and have it pass through vs? I've been trying this with no luck so far. Also was considering a vsspro controller and finding the signal on the ecu and also the cluster to bypass the abs module entirely. The p0600 code can go away with romraider and I can deal with the er hc and ss Link to comment Share on other sites More sharing options...

BrandonspecB Posted March 3, 2021 Share Posted March 3, 2021 Still using a JDM ECU? Is the pinout the same as the ECU that came in the car? Does your coolant temp gauge work or does it max out? Link to comment Share on other sites More sharing options...
Deeregamer Posted March 3, 2021 Author Share Posted March 3, 2021 Every electrical component and wiring is from the same 06 usdm gt parts car. I never saw it run or turn on before hand as it was half way taken apart when I got it though. I wish I made it work in the other chassis to make sure everything was functioning properly before hand just so I had a constant Link to comment Share on other sites More sharing options...
BrandonspecB Posted March 3, 2021 Share Posted March 3, 2021 Are the ABS modules the same between your car and the parts car? Are all the modules from the same car? Gauge cluster, BIU, ABS, ECU? I'm not an expert at CAN stuff, but when I was buying my standalone I contacted Haltech about CAN compatibility with my car because Haltech is CAN compatible with a 2005 ADM Legacy 3.0. They said it wouldn't work with my car because the CAN addresses have to be figured out for each year and model of car. And they were right. I tried connecting the Haltech to my car's CAN bus and selected the ADM Legacy CAN option and it wouldn't work. No vehicle speed at the ECU, no coolant temp at the gauge cluster, errors in the gauge cluster display. Link to comment Share on other sites More sharing options...

Everything should be from the same car as it runs and drives and does everything but give me vs. I've had 2 or 3 parts car come and go so I may have the wrong abs module though. I know I left the bcmu ecu and stalk w/ key togther though. It all came from an 06 gt sedan. BTW your car is amazing! Been keeping up on the build as best I can. I was honestly thinking about calling haltech as the have pnp ecu now but if your saying it doesn't work I guess I won't. I really need to sit down with a volt meter and check that abs plug out and see what up. I'm not the greatest with electrical diagnostic so I've tried everything I can outside of that first.

BrandonspecB Posted March 3, 2021 Share Posted March 3, 2021 You can also check for ABS codes. See if that can shed some light on what's going on. Link to comment Share on other sites More sharing options...
boxkita Posted March 3, 2021 Share Posted March 3, 2021 the race wagon has alot of stuff removed, however, it still has the oem abs and key/ignition setup. That was with factory support, too. Have the vaca pix yielded any help yet? Build my car Boxkita Track days Link to comment Share on other sites More sharing options...
Deeregamer Posted March 3, 2021 Author Share Posted March 3, 2021 You can also check for ABS codes. See if that can shed some light on what's going on. I can't even connect to the abs unit. Tried the cluster trick and an Innova scan tool. I get er ss and er jc on the cluster and a p0600 code which is high-speed can fault. I have power at the abs fuse in the fuse pannel so I have to dig deeper into where I'm loosing signal back from the abs pump or if it's getting power at all Link to comment Share on other sites More sharing options...

Deeregamer Posted March 4, 2021 Author Share Posted March 4, 2021 any clue where the b310 connector is? its for the vdc but seem to be a seperate module from the abs which is the 301 connector Link to comment Share on other sites More sharing options...
Deeregamer Posted March 4, 2021 Author Share Posted March 4, 2021 wait scratch that. I don't have vdc at all or I missed plucking something out of the parts car Link to comment Share on other sites More sharing options...
Deeregamer Posted March 4, 2021 Author Share Posted March 4, 2021 Anyone find an i/o diagram for the b301 connector? Couldn't come up with one last night. I think that's where I'll find my issues. Link to comment Share on other sites More sharing options...

Deeregamer Posted March 6, 2021 Author Share Posted March 6, 2021 found the i/0 for b301 and also a diag procedure for no communication to the abs module. would be real funny if fuse 13 was dead after all this haha Link to comment Share on other sites More sharing options...

Deeregamer Posted March 7, 2021 Author Share Posted March 7, 2021 so I found no power at any of the wheel speed sensors on the b301 and also no power for the can communication. guess i need to follow those all back and figure out whats going on.

Deeregamer Posted March 7, 2021 Author Share Posted March 7, 2021 Think I found the smoking gun. Have no voltage on pin 18 which is my main power source for the abs module that is fed through the 30 amp fuse on the fuse pannel I now have in the glove box. Ran the probes from one end to another and I have an open circuit it seems. Guess I do suck a soldering Link to comment Share on other sites More sharing options...
WhiteSoobydoo Posted March 10, 2021 Share Posted March 10, 2021 This is one sweet build! How much boost does it run? I kinda wish I'd have tried this as it's far cheaper for a JDM than rebuilding my EJ255 for the O5 LGT. Link to comment Share on other sites More sharing options...
