Manufacturer summary

Original wording in English

Some Elantra (CN7A), Sonata (DN8A) and Santa Fe (TMA) vehicles may exhibit the Electronic Parking Brake (EPB) warning light on due to brake fluid entering the HECU electrical connector. DTC C1501 (EPB Switch Failure) may be present, but EPB performance remains unaffected. This bulletin describes the procedure to inspect, and if necessary, replace the Hydraulic Electronic Control Unit (HECU).

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.
