Background:
I bought this car in late 2012. It's been a SCCA T1 car for a decade. It's a 1999 FRC but has an LS6 motor. The car's computer is from a 2003 (as shown by HP Tuners). I don't know what else was converted on it (torque tube, rear, ABS system).
I think ABS was working fine, as I autocrossed it and open tracked it at NJMP and did really well with no issues and I drove it hard and didn't skid or flat spot any tires using race pads.
Then I took it to the Glen and had a near disaster with brake lockup caused by ABS wires from the right front tire melted against the exhaust. I noticed the C1255 code (EBCM internal malfunction) after the spinout there.
Cleared the codes and I saw it again yesterday (H = history).
From what I'm reading, if I have this error (C1255), the ABS should not be functioning. But I think it is.
Next step: put on old worn out slicks, wet down my driveway and drive to invoke ABS to confirm.
If a broken/malfunction EBCM means that I don't have traction control, that is fine since I don't use traction control. But I want the ABS to be functioning.
The numbers on the EBCM read:
ABS-5/TCS/MSVA
Delphi D
model: 09356961
serial #52230016
ABS pump reads:
Bosch 927
0 265 219 008
A 06911 094
962 05 37
10417324
Option codes sticker from glove box but very difficult to read but this doesn't have the active handling option (active handling RPO # JL4). I think the Non-Active Handling code is JL9 but I don't see that on the sticker either:
