I'd like to apologize for this long post, but I really need help in trying to figure this out. I've searched to no avail.

Recently installed a Blitz turbo timer with a harness on my STi using these instructions (for enabling the factory alarm system while the turbo timer is running), and my ABS is now staying on immediately after the install.

Instructions I got from Mach V Motorsports:
Step 1: After installing your turbo timer with the under dash panel off, locate the black relay box on top of the fuse panel. Unbolt 1 (10mm) bolt and cut the Green with Black wire. Tape both ends of the wire and reinstall relay box. Reassemble under dash panel.

Step 2: Remove the panel in front of the armrest by pulling up on the cup holder. Disconnect the power mirror terminal. Locate the wiring terminal for the security system. Cut the Grey Wire. Tape both ends. Reattach power mirror terminal and cup holder panel. Enjoy!

The green wire with the black stripe under the dash leads to the keyless entry relay box, so I doubt that could be the cause. When I pulled the panel with the cup holder out and looked for the gray wire, there were two of them. Thick ones. I checked to see where they led to. One of them led to a harness that wasn't connected to anything. The other one led to a sensor near the back next to the arm rest, with a stamp on it that says "do not disassemble." Since the second gray wire I checked was connected to the sensor, I figured that would be the one, and cut it. Put everything back together and started the car to test the turbo timer, and to see if my alarm would arm with the car still running. It armed, but now the ABS light stayed on. I tried reconnecting the gray wire, but the ABS light still stays on.

Any idea what the cause would be? What exactly is that sensor for? Any help would be appreciated. Thanks in advance.

 

your e brake line tap is more than likely the culprit... undo it and see if the light goes away.

do not go to the dealer at any cost. figure this out first or else they will charge you alot of $$$$..


undo the negative on the battery as well to reset.


let me know, here to help

Is the e-brake line tap the connector that plugs into the e-brake? Dumb question, but I just wanted to verify. I'll try that tonight after work to see if that cures the problem. I also checked both ABS fuses, and they were good. Would anyone happen to know what that sensor (with the gray wire that I originally cut) is for?

Thanks for the help Gino. I really don't want to have to take my car to a dealership.

Hey Gino. I just took a quick look under the panel where the e-brake handle is and couldn't find the e-brake line tap. Shouldn't it be located there? Thanks again for your help.

 

the line is on the passenger side of the center hump. Hiddeen under the carpet. More towards the rear of the hump along side the end of the e brake lever base

look for it...
