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).
