Ford F5JL-12A297-DA Controller

F5JL‑12A297‑DA is a Ford LRG/LSG ignition control module (ICM) used in 2.5L diesel and gasoline engines. Common failures include internal relay burnout, fuse or circuit board damage from over‑voltage spikes, and connector corrosion that causes intermittent spark loss or engine misfire codes. First‑check diagnostics: verify battery voltage and alternator output, inspect the ICM’s power and ground connections for continuity and signs of burn‑tite; check the module’s diagnostic LEDs or error code readout via a scan tool; visually inspect the wiring harness and connectors for frayed insulation or loose pins before proceeding to internal component testing.[oss-gpt-20b] Post Comment
