P0642 code is vague

I agree, the P0642 code doesn't specify which component is at fault. Unfortunately, I do not have the factory service manual for your vehicle, but in most vehicles, the same circuit powers 3-7 components. Once you know which components the circuit is connected to, disconnect each component, and check the circuit between the component and the PCM or replace the component. 

Since I don't have the factory service manual for your vehicle, I can't recommend which component to check.

This video can give you an idea how to diagnose the problem:
