does anyone know what this means?

my check engine light was on so I went to Autozone and this is what they told me:

OBD code: 1298
Electric Load Dectector (ELD) Circuit
High Input

Probable causes:
1- poor electric connection
2- failed ELD

Nakamichi

Either the Either the Electrical Load Detector (ELD) needs to be replaced, and/or there's a opening in the circuitry path between the PCM/ECM and ELD.

Year/Engine Size?

AznX TL

by looking at his wheels it looks like a 99 2.3CL

JORTS

its a 1998 2.3 CL....

is that something that needs immediate attention?
is it an expensive cost?

thanks for the info!

ELD Diagnostic Steps

Problem Verification:
1. Do the ECM/PCM Reset Procedure. (remove backup radio fuse for ~15 seconds)
2. Start the Engine.
3. Turn on headlights.

Q1. Does DTC P1298 appear?

NO -
1. Intermittent failure, system is OK at this time. Check for poor connections or loose wires at C256 (ELD) and ECM/PCM.
2. End of Diagnostics.

YES - Check for an open in the wire (GND line):
1. Turn the ignition switch and headlights OFF.
2. Disconnect the ELD 3P connector.
3. Check for continuity between body and round and ELD 3P connector terminal No. 1
4. Goto Q2.

Q2. Is there continuity?

NO -
1. Repair open in the wire between ELD connector and G402.
2. End of Diagnostics.

YES - Check for an open in the wire (EL line):
1. Disconnect the ECM/PCM connector A (32P).
2. Check for continuity between the ELD 3P connector terminal No. 2 and ECM/PCM connector terminal A30.
3. Goto Q3.

Q3. Is there continuity?

NO -
1. Repair open in the wire between the ELD connector and ECM/PCM.
2. End of Diagnostics.

YES - Check for a malfunction in the ELD:
1. Reconnect the ELD connector and ECM/PCM connector A (32P).
2. Start the engine and allow it to idle.
3. While measuring the voltage between the ECM/PCM connector terminals A30 and B20, turn the headlights on (low beam).

Q4. Does the voltage drop?

NO -
1. Replace ELD.
2. End of Diagnostics.

YES -
1. Substitute for a known-good PCM/PCM and recheck. If symptoms goes away replace the original ECM/PCM.
2. End of Diagnostics.

ELD 3P Connector (C256). This should plug into the ELD, which is located in the fuse box in the engine compartment.

Ahh.. Another productive work day in the IT world. Good luck in troubleshooting.

i got the guys at autozone to erase the codes so my check engine light would go off...so far the check engine light has not came back on....does that mean the problem is not that big of a deal?

thanks again!

Nakamichi

Probably just a fluke (loose connections, etc). I say don't worry about it. If the light comes on, go through the troubleshooting procedures above.

Hi,

Regarding the ELD 3P connector in the fuse box, is pin 1 or pin 3 the pin closest to the firewall?

I wasn't sure what the double line above the "1" indicated.

Thanks.

dont bother with the code it wont throw a CEL on anyway i disconnected mine. all it does is restrict the alt from running when the car senses there is no load on the altinator. complete BS dont even worry about it
