Test D: Electronic Shift Functional Test
Pinpoint Test D: Electronic Shift Functional TestNormal Operation
When the vehicle is operating in 4x4 HIGH or 4x4 LOW, all 4 wheels rotate at the same speed. The amount of traction the vehicle can achieve is dependent on the amount of traction each tire can establish with the road surface. In order for the 4WD system to operate correctly, each wheel/tire assembly must have matching sizes and the front and rear axle ratios must match.
Possible Causes
^ 4WD indicators
^ 4WD control module
^ Transfer case and related components
^ Wheel/tire assemblies
