The bulletins listed name this code in NHTSA's summary, or are about the same components. A bulletin or a recall listed here may apply to the model year. None of it is a diagnosis.
This code is specific to a manufacturer and is not described here. Its meaning is in the manufacturer's service information.
| SSM 48578 | 2020-03-03. Service bulletin. Some 2013-2016 MKZ vehicles equipped with adaptive headlamps may exhibit a Check Headlamp System fault message in the instrument panel cluster (IPC) after the right headlamp is replaced. Diagnostic trouble code (DTC) B1D65 may also be stored in the headlamp control module (HCM). To correct this condition install a new right headlamp (13008). Right headlamps built on or after 17-Oct-2019, or reworked headlamp assemblies identified with a green dot on the box and/or a green paint mark on the headlamp near the part number label, will no longer have this issue. For claiming, use Causal Part (13008) and applicable Labor Times in the Service Labor Time Standards (SLTS) Manual. |

| SSM 48406 | 2020-01-08. Service bulletin. Some 2013-2016 MKZ vehicles equipped with adaptive headlamps may exhibit a Check Headlamp System fault message in the instrument panel cluster (IPC) after installation of a new right headlamp. Diagnostic trouble code (DTC) B1D65 may also be stored in the headlamp control module (HCM). This may be due to a quality issue with the right headlamp service part, which was corrected on headlamps built on and after 17-Oct-2019. In addition, some headlamps with Earlier build dates were reworked with corrective actions and may be installed. Reworked headlamp assemblies are identified by having a green dot on the box and/or a green paint mark on the headlamp near the part number label. For claiming, use the headlamp base number as the causal part and applicable labor from the Service Labor Time Standards (SLTS) Manual. |
| SSM 48263 | 2019-11-05. Service bulletin. Some 2013-2016 MKZs vehicles with Adaptive Headlamps may exhibit a Check Headlamp System fault message in the instrument panel cluster (IPC) after one or both headlamps were replaced. Diagnostic trouble codes (DTCs) B1D64 and/or B1D65 may also be stored in the headlamp control module (HCM). Confirm the headlamps illuminate normally, but do not attempt additional repairs at this time. Engineering is investigating, monitor OASIS for updates. The swivel function will remain inoperative until a corrective action becomes available. The headlamps will continue to function to fully meet all applicable lighting requirements. |
