Manufacturer summary

Original wording in English

This Preliminary information communicates that a vehicle may be encountered with an SES light on and code P059F and P05AE DTCs Set in Snowy or Icing Conditions. The technician is instructed that If no issue is found after completing the diagnostics in SI for both DTCs, do not replace the shutter assembly. Engineering is currently investigating.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
