P1297 Isuzu Code - Electric Load Detector Circuit Low Voltage
Quick Answer
The Electric Load Detector (ELD) measures the main current flow and sends that signal to the Engine Control Module (ECM) to command the alternator charging system to get fuel efficiency and decrease the drag of the engine when starting. Common causes include Faulty Electronic Load Detector Unit, Faulty Engine Control Module (ECM), Electronic Load Detector Unit harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
