Manufacturer summary

Original wording in English

This PI advises dealers that if the K160 Brake System Control Module sets DTC P0606 along with P0562 and/or P25A2, additional diagnostic aids should be followed before replacing parts. The PI provides guidance to inspect for low voltage conditions, wiring, terminal concerns, and module communication issues that may cause false or intermittent EBCM DTCs.

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.
