| SSM 50210 | 2021-10-29. Service bulletin. POWER TRAIN:DRIVELINE:DRIVESHAFT; ENGINE; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some 2021 Bronco vehicles built on or before 14-Sep-2021 may experience a loss of power when driving with various illuminated warning indicators displayed in the instrument panel cluster (IPC). This may be due to an improper seating of the wiring harness push pins to the driveshaft loop which can cause an interference condition between the rear driveshaft and the 14405 harness near the C2370/C350 connector. If suspected, inspect the harness and connector for damage and repair as necessary. Once inspected and/or repaired fully, seat the harness push pins to the driveshaft loop. |
