If the ELD value is greater than 18 amps, disregard this bulletin, and continue with normal troubleshooting.
NOTE:
A faulty ELD may cause the charging system to fluctuate between 12.5-volt and 14.5-volt modes with the engine running and the headlights
on. This fluctuation causes the headlights to dim. Under normal operating conditions, the charging system operates in the 14.5-volt mode.
^
If the headlights do not dim, but DTC P1298 is stored in the ECM/PCM:

For Accord, go to REPAIR PROCEDURE A - ACCORD
