Was told by dealer that fix was to replace the bearing on that wheel as sensor was part of the assembly. Whatever they did fixed the ABS problem (or, at least, the ABS light). I also had a Fan 2 (not 1) control circuit code. That resulted in swapping the BCM and ECM out (3 times). I've also read and been told that many of these problems are related to bad grounds and to check grounding points (there are apparently 3-4 such contacts under the hood, maybe under the dashboard cowl). I would be a bit worried about the ABS although if a solid ground makes the problems disappear, good enough for me. My temp runs 220F. HTH and good luck!

Then some that matter-
B1405, Control Module Voltage Reference Output 2 Circuit Low Voltage.
Not sure about this one- the voltage is ~14.8 V (from memory) while running, which is within spec.
C0035, LF wheel speed sensor circuit malfunction
I assume this is why my ABS light is illuminated. I guess I'll check the wheel sensor next. Hopefully a simple fix.
P0480, Fan 1 Control Circuit
This one concerns me- I have swapped all the relays and checked all the fuses, but it persists. On a hot day, driving very slowly, the engine coolant temperature goes up to 200 F, and the fan- I think- comes on about 220 F. I have hardly ever heard it come on and I suppose I should check the fan operation with a direct connection to the battery.
Tooling around, the coolant runs about 200 or less. What temp is normal?
