Hello everyone, I have a practice to plug in my Techstream every half a year or after the oil change to see if anything is wrong. While there is no VSC CEL ABS on my dash, TS reports C0205 Front Speed Sensor LH Circuit and C1223 ABS Control System Malfunction. I read some of the older threads pointing to the wire harness yet I am curious about the clean dashboard. Anyone has experienced this combination of clean dash but TS code on C0205 and C1223? Thx.

 

Make sure it is not history.

 

Isn't Curr Conf = now? Anything I shall click on and check on TS further? Thx.

 

I always reset all codes, then go for a drive to see if they come back.
However, the fact that there is a possible issue with the wheel speed sensor and there is also an issue with the dash warning lamp that reports the failed wheel speed sensor is indicative of a wiring fault.

 

Guess I gotta find time to ohm the speed sensor and the wiring harness. CEL led up 6 months ago about a leaky Y pipe. So, the dashboard light should work if it triggers...

 

Ohmed the sensors and harness. Everything works as it should. With the ignition in on position, I unplugged the wheel speed sensor. VSC appears immediately. So, the communication between the wheel speed sensor and the ECU is confirmed. I just clear all DTC and call it a day. See if it comes back later.
