- Summary
- DESCRIPTION Some customers may experience ATF seepage from the High-Voltage (HV) motor terminal area. If ATF seepage is confirmed at this location, one or more of the following conditions may occur: ATF is leaking from the HV cable. ATF is leaking from the inverter connection. This is caused by through-hole porosity generated during manufacturing of the intermediate terminal block (busbar), allowing oil to seep from the component. To eliminate this concern, an Impregnation treatment (a sealing process in which resin, oil, or other liquids are infused into minute internal voids in the material, such as porosity, pinholes, or cracks) is applied to the aluminum plate portion of the busbar. REPAIR PROCEDURE 1. Verify the customer concern. 2. Replace the busbar with a new one.
