Normal Operation and Fault Conditions
The AWD system uses input data from the ABS module wheel speed sensors as inputs to the PCM. A dissimilar spare tire size (other than the spare tire provided) or major dissimilar tire sizes or incorrectly inflated tires between the front and rear axles could cause the AWD system to stop functioning correctly.
