Deere & Company 90-155900-04 RE528702 Engine control

The RE528702 is a 12‑volt Level 18 Engine Control Module used on John Deere L‑series tractors and other models such as the 4024HT. Common failure points for this class of ECM include power supply degradation, internal fuse or relay blowouts, corrupted firmware, and intermittent sensor input errors that can cause misfires or idle instability. First‑check diagnostics: verify proper 12 V rail voltage at the module’s terminals; inspect all connectors and fuses for continuity and signs of corrosion; review any diagnostic trouble codes (DTCs) stored in the ECU using a compatible scan tool to identify specific fault codes before proceeding with component testing or reprogramming.[oss-gpt-20b]
