Code 1223 C1224 C1246 (1 Viewer)

[Yangster]

Hi,

Hi I'm new to this forum. Just got a 2005 lx 470 with 103k miles two weeks ago. Today I bought a bluedriver obd 2 reader. When I ran the full system scan it returned 3 codes:

C1223 ABS control System malfunction
C1224 NE signal circuit
C1246 Master Cylinder Pressure censor

No warning lights whatsoever on the dashboard, car runs smooth and fine. So I just cleared the codes.

Is this something I need to worry about?

Thanks!

i also have the c1223 and c1246 with no warning lights.

Do you hear the ABS pump running constantly or every minute?

No.

I just found a C1224 NE signal circuit with Techstream on.my 100.
I cleared it and wil check again later to see if it was a fluke. I have no detectable brake issues.
The indication is a bad sensor or damage to a harness someplace. Or a Gremlin fed after dark.
