ABS + Traction Control Lights On

HapaZ · 09-28-2021, 02:48 PM

I was able to read the codes on the ABS system and got the following.
C1104 - Left front sensor
C1107- Right front sensor 2
C1108 - Left front sensor 2
C1155 - Brake Fluid level low
C1109 - Power and system ground fault

This seems more than a simple sensor issue. Could the ABS module be going bad on me?

I had intermittent problems like this where I also lost instruments functions. It turned out to be defective ABS controller which I believe was causing fault on CAN bus. Fortunately, it was replaced under warranty; but it took almost 2 months for my dealer to get a replacement part from Japan and this was after escalating the issue as high as possible, because I said (and my dealer agreed) this was a safety issue.

Hope your outcome is different; but I doubt you will able to diagnose by yourself and just want to warn you not to go replacing a bunch of parts before you get complete diagnosis.

Yeah I’m taking it in to my mechanic. I do think my abs module is faulty or there is a wiring issue somewhere though. Doesn’t make sense that 3 sensors would simultaneously go bad on me.
