How to Fix the ELD Circuit With a High Input

Clear the electric load detection fault code from your Honda.

Honda vehicles have a unique automatic control over the vehicle's alternator. When presented with a high electrical load over two amperes, the malfunction indicator light commonly appears on the dash. Additionally, the fault code is present when a service technician or inspection agent tests the vehicle. This may prevent the vehicle from passing inspection, over a relatively meaningless code.

Things You'll Need

• OBD-2 tester
• Ratchet and socket set

Instructions

1. Locate the 16-pin OBD-2 data port, which is found under the glove box in most Honda vehicles.

2. Flip open the protective cover on the port. Plug your OBD-2 tester into the port. Turn the tester on, then start the vehicle.

3. Examine the test meter. Look for P1169, corresponding to the "Label Circuit High Voltage" fault.

4. Clear the fault code from the vehicle by removing the negative battery wire for 30 seconds or more, using the ratchet and socket set. Re-attach the wire and start the vehicle. The code should be cleared, indicated by the MIL light disappearing from the dash cluster and subsequent testing at the port.

Tips & Warnings

• If the fault has a known cause such as a high-powered car stereo, feel free to clear the code as needed. However, if it re-appears for no apparent reason on a repeated basis, it is wise to have the cause of the fault checked at a dealership or trusted service center.
