After searching through threads to get the Part Number and TSB for the replacement of the ELD to fix the Dimming Headlight problem I decided to put a post together that has it all in one place (Sticky???).
Name: Electronic Load Detector
Part Number: 38255-S5A-003
Elements effected: Any that has dimming headlights when gas pedal is released
Cost: +/- $30
Service Bulletin: http://jphangingout.googlepages.com/ELDBULLITEN05034.PDF
Ok now for my $.02. The fuse box is kind of a pain to remove. Well it was for me anyway. If you want a quick shortcut to keep from removing the fuse box all you need is a thin blade screwdriver.
First, follow the steps in the TSB for disconnecting battery etc. but stop when it gets to the removal of fuse box (step 3). Skip steps 4,5 and 6. When you get to the part where you pull the ELD out there should be enough slack on the wires/plug for the ELD that you can pull the ELD part way out and expose the plug. Here you can use the small screwdriver to depress the release tab on the plug. It will be right in the middle on the passenger side. Just push it in and pull up. Here's a shot of the ELD removed:
Next take the screwdriver and from the drivers side exert just enough force on the underside of the plug to plug it into the new ELD. This should slip in relatively easily.
Just to be sure the clip is inserted you can get at it from the passenger side and push upwards a little more.
After that you can reassemble everything according to the TSB. Hopefully this helps.
