Electronic Load Detector
measures electrical load - used to determine if the alternator should be in low or high output mode.
Since Hondas are running so lean at idle, virtually any load will cause the idle to
drop. Even small electrical loads, such as the turn signals, will cause the idle to
fluctuate. The electrical load detector (ELD) was added to later model Hondas to
monitor for any significant electrical loads. It sends a warning signal to the ECM
before the load has a chance to effect the idle. The ECM makes slight adjustments
to the idle air control (IAC) valve, injector PW, and ignition timing to compensate
for the electrical load.
