ACTION

Before doing any other diagnostics or repair,

Inspect (and if needed) repair the ABS/VDC wheel speed sensors/signals.

^ Refer to the Service Manual as needed.

^ Perform "line graph" diagnostics on each sensor while driving. Inspect and repair as needed any sensor with a spike in the output signal or that has a different value than the other sensors.

NOTE:
^ The most likely cause of the above concern is an issue (sensor, wiring, or debris on sensor/rotor) with the output signal from an ABS/VDC wheel speed sensor.

^ A weak or erratic output signal from a wheel speed sensor can cause poor performance or lack of power from a stop, or at low speeds.

^ Do not replace the TCM or CVT unit when repair of a signal from a wheel speed sensor will resolve the issue.
