This bulletin provides a diagnosis and repair procedure for DTC P172A and / or P0B0B. When either of these DTCs is stored, a leaking o-ring which seals the electric oil pump relief valve may allow CVT fluid to enter the pump?s electric motor. Although current Service Manual diagnostic procedures instruct replacement of multiple components, this information will help isolate the actual failed component for a more cost-effective repair. NOTE: The relief valve is now available as an individual part. If there is no damage to the drive motor case assembly, refer to TSB 16-108-17R for the parts needed and Service Procedure for replacing just the relief valve.
