| SSM 48260 | 2019-11-05. Service bulletin. ELECTRICAL SYSTEM. Some 2017-2020 Ford and Lincoln vehicles equipped with a TCU may exhibit inoperative remote features via Ford Pass/Lincoln Way mobile app, incomplete user authorization and/or accessory protocol interface module (APIM) DTC U0198 or no modem electronic serial number (ESN) displayed. To correct this condition prior to programming, remove the TCU fuse for 5 minutes then reinstall. Delete all previous session files for the vehicle. Verify that the electronic serial number (ESN) is now displayed. Start a new IDS/FDRS session. Program the TCU to the latest IDS/FDRS version level. Make sure you are connected to the internet before retesting. If the concern is still present, follow normal diagnostics in Workshop Manual(WSM), Section 415-00. Refer to PTS OASIS home page for TCU version identification. For claiming, use causal part 14G229. |

| SSM 48123 | 2019-09-06. Service bulletin. ELECTRICAL SYSTEM. For Ford and Lincoln vehicles that require positive or negative battery terminal replacement, it is not necessary to replace the complete battery cable harness (14300 and 14301) for this concern. Positive battery cable clamp BT4Z-14450-AA and negative battery cable clamp BT4Z-14450-BA are available for this type of repair. Do not cut or shorten the battery cable, instead carefully remove the affected battery cable clamp and clean the cable end as necessary to preserve wire length. Some rework may be necessary for some vehicle environments. Bend the new positive battery cable clamp as needed and crimp it to the existing battery cable. Make sure to use heat shrink tubing over the battery cable to battery cable clamp connection. Obtain the heat shrink tube locally. |
| SSM 48108 | 2019-08-07. Service bulletin. ELECTRICAL SYSTEM. Some 2015-2019 vehicles may experience a no crank concern due to a security access key table error. When attempting to program keys or perform a parameter reset, the procedure may fail and the appropriate Ford diagnostic scan tool may display an error 232: Key Table Not Allocated. If this error message is encountered, the body control module (BCM) is internally damaged and requires replacement. The BCM should only be replaced for this condition when the 232 key table error message is present. If the 232 key table error is not present, follow normal diagnostics for the no crank condition. For claiming, use causal part 15604 and applicable labor operations in section 10 of the Service Labor Times Standards (SLTS) manual. |

If an update is available refer to WSM,Section 415-00 and update the APIM software. After Installation, complete pop-up appears, remove USB flash drive and install into IDS tool to update Ford database. Perform a complete ignition cycle by turning the key off for 5 minutes which is critical for a successful installation. If no updates are available or a blue or black screen is present after an update refer to WSM, Section 415-00 for diagnosis or SYNC 3 intermittent blank screen GSB for tips. For claiming, use causal part 14G371 and applicable labor operations in section 10 of the SLTS manual. Section |
