TITLE: Diagnostic Trouble Codes After WWK-94

APPLIES TO: All models affected by WWK-94

SERVICE TIP:






If you have a vehicle come in with any of the following Diagnostic Trouble Codes (DTCs), check the Vehicle History to see if prior work was performed on the transmission that involved removal of the transmission oil pan. Subaru has received several calls concerning these codes on vehicles where the WWK-94 campaign had recently been done.

In most cases, these codes were the result of a loose ground wire in the transmission where it fastens to the valve body. Tightening the ground wire was all it took to repair the problem.

Be advised that this condition is considered a comeback and is NOT a matter for warranty.
