This bulletin announces a design change to the EPB adapter cord harness connector. In some cases, the retaining tab of the connector may become damaged as a result of removal or installation for diagnosis and later and cause DTC C1956 or C1957 to set and the brake warning lamp to illuminate. The retaining tab portion of the connector has been changed to improve its durability and prevent recurrence of the DTC. If there is no prior history of disconnection and the connector lock tab is not damaged, check for another possible cause for these DTCs.
