1. What does P0606 mean?

Verified evidence identifies P0606 in a Subaru Tech Tips article locator as “DTC P0606, Control Module Processor: Diagnostic Hints.” The supplied material does not establish a vehicle-specific fault definition, symptoms, repair, driving safety, or charging safety for the listed EV models.

2. Technical explanation

The supplied official NHTSA-hosted manufacturer communications are article locators. Their evidence summaries list “2019MY Ascent: DTC P0606, Control Module Processor: Diagnostic Hints.” The diagnostic record’s canonical title and meaning also contain unrelated article-locator text concerning 2015MY Legacy/Outback seat-heater operation. Therefore, the verified evidence supports only that P0606 is referenced in a Subaru Tech Tips locator under “Control Module Processor: Diagnostic Hints”; it does not provide the underlying diagnostic procedure or a model-specific interpretation for Crosstrek, Solterra, Trailseeker, or Uncharted.
