What P1297 means on specific makes

Honda / Acura CAUTION

The ELD, which monitors electrical load to control charging, is reading low voltage. A Honda-specific charging-system input fault; can affect alternator control and idle.

  1. Failed ELD unit (in underhood fuse box, ~$60-150)
  2. Wiring/connector to ELD
  3. Charging system issue

Check first: Check ELD signal voltage in live data with loads on/off; the ELD is usually integrated into the underhood fuse/relay box.
