P1298 HONDA - ELECTRIC LOAD DETECTOR HIGH VOLTAGE CIRCUIT
The fault code P1298 OBDII is a manufacturer specific code related by Honda as a fault in one of the components of the charging system, which is commonly known as ELD (Electric Load Detector). It is set when a high voltage condition is detected above the levels allowed. ELD devices are used only in Honda vehicles.
The Electrical Load Detector transforms the current in the fuse and relay box located under the bonnet. Although the design of the ELD could be confused with a fuse, its function is to detect current drawn from the battery and charging system. The Powertrain Control Module regulates the voltage applied to the coil according to the signal received by the ELD. In this way, a variation of the alternator voltage output allows meeting the charging requirements.
When factory accessories are used, usually those of the air conditioning system and the lighting system, the output of the alternator is close to 14.4 volts. On the other hand, when you do not use such accessories, it is necessary to reduce the alternator output to increase the fuel efficiency and life of the alternator.
The reasons to set DTC code P1298 OBD2:
