Yes. If voltage on the green/red wire doesn't drop when you turn on the headlights, the ELD has failed. Fixing it requires replacing the main fuse box. A hard ELD failure should set OBI) II code P1297 or P1298.

(Honda CR-V 2002 Mod. AUT) My problem is that the car starts but stops after three / four seconds. MIL light is on. When my mechanic is using the Scan Tool, he gets the code "P1298 unknown...


P1298 is a result of a alternator wire short. check fuse 6 in the driver's under dash fuse panel and see if it is blown. If it is check the black/yellow wire of the alternator and see if it is shorted to ground. repair the wire and replace the fuse. Also you might get the O2 sensor code as a result of this fuse being blown also.

My brother in law asked me to find out what is the purpose of the eld unit inside the under-hoodfuse/relay box? he has a 1998 honda civic. we cant get the alternater to charge,even after changeing it out...


The ELD unit or Electrical Load Detector functions to monitor and regulate the output of the alternator. The ELD is located in the fuse box under the hood near the battery. It's a (typically) red rectangular box.
If the ELD unit is malfunctioning, it is very possible that it is preventing the alternator from putting out a charge. I do not know of a way to test it, other than to replace it.
Just to make sure, first check all battery connections, including the engine ground, for corrosion. All terminals and wires should be super clean, in order to rule out such a simple matter of a poor connection (this is very common). Also , make sure the power wires going into the fuse box and the ELD socket are free of corrosion.
I hope this helps. Good Luck!

P1298 Code Fuel/Air Metering


Are you sure you wrote the correct code. According to Honda, P1298 is a high ELD circuit voltage. If what I just put is correct, Honda has a service bulletin as this is a common problem( it could be another fault, but this is the most likely choice).
The ELD has a bad solder joint. I have done several of these, you will need to replace the ELD, and this is how.

1 D/C the negative battery cable (make sure you know your radio code, it will be needed to use the radio again)
2 Unbolt the fuse box that is in the engine bay.
3 Attached to the fuse box underneath there is a plastic cover, remove this cover.
4 There is a 3 pin connector under this cover. Remove it
5 Flip the fuse box back over, there are 2 big fuses bolted down, a 40 A and a 80A
6 Under these fuses is the ELD, remove it and pull the bar that sticks out of it.
7 Stick the bar in the new ELD
8 Put everything back together. Do the idle learn (just idle the car for 10 minutes with no loads on such as radio, headlights etc..)


This is probably the first thing they will do if you bring it to Honda assuming the code you have is P1298.

I have a 2004 Honda Civic 4 cyl. That has a code P1298 ''Manufacturer Control, Fuel/Air Metering''. This, I believe is causing multiple cylinder misfires. Can anyone tell me what the culprit is of the...


OK. Here's how to diagnose the P1298 error.

DTC P1298: ELD Circuit High Voltage

1. Reset the ECM/PCM (see HOW TO RESET THE ECM/PCM ).
2. Start the engine.
3. Turn on the headlights.

Is DTC P1298 indicated?

YES - Go to step 4.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the ELD and at the ECM/PCM.

4. Turn the ignition switch and headlights OFF.
5. Disconnect the ELD 3P connector.
6. Turn the ignition switch ON (II).
7. Measure voltage between body ground and ELD 3P connector terminal No. 1.

Is there battery voltage?


YES - Go to step 8.
NO - Check the No. 4 ACG (10A) fuse in the under-dash fuse/relay box. If the fuse is OK, repair open in the wire between the No. 4 ACG (10A) fuse and the ELD.

8. Turn the ignition switch OFF.
9. Connect ELD 3P connector terminal No. 3 to body ground with a jumper wire.

10. Disconnect ECM/PCM connector E (31P).
11. Check for continuity between body ground and ECM/PCM connector terminal E15.

Is there continuity?

YES - Go to step 12.
NO - Repair open in the wire between the ECM/PCM (E15) and the ELD.

12. Check for continuity between ELD 3P connector terminal No. 2 and body ground.

Is there continuity?

YES - Go to step 13.
NO - Repair open in the wire between ELD and G201.

13. Reconnect the ELD 3P connector and ECM/PCM connector E (31P).
14. Start the engine and let it idle.
15. While measuring voltage between ECM/PCM connector terminals A24 and E15, turn the headlights on (high).

Does the voltage drop?

YES - Update the ECM/PCM if it does not have the latest software, or
substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
NO - Replace the ELD.
