This is actually for my sister's 2002 Aztek. It has an ABS light and so I connected HPT to it and got those codes...

[Brake] C0035 - LF Wheel Speed Circuit Malfunction (History)
[Unknown] U1040 - Loss of Class 2 Communications with ABS (History) (Immature)

My question is that is the U1040 error because it cannot communicate with a bad wheel speed sensor on the left front? Or should I be looking at something else like the module for the ABS itself. The WSS are part of the hub and wouldn't be too hard to replace but I didn't want to go slap on a $100 part if it won't do anything. Is this just a bad sensor or do you think it is something in the circuit?

Thanks

If the sensor is external look at it and see if its covered with metal shavings. If not..... The loss of class 2 with the abs seems like a wire or smothang
