OBD-II / DLC3 pinouts (headlight leveling system problem)
 

Does anyone have the pinouts for the DLC3 connector on the SC430 (2003)?

It's the OBD-II connector, but the service manual refers to it as the DLC3 connector.

I replaced my headlight leveling sensor on the back axle this weekend.

However, instead of getting an intermittent headlight-failure lamp...I'm getting a constant one.

Found a link to a set of instructions that says after replacing the sensor, I need to short "XDA and CG terminals of the DLC3 connector and operating the light control switch."

Here's the link to the article. Granted, it's for a Prius, but it's still the Toyota headlight leveling system. And a search for SC430-specific stuff turned up ziltch.

Any help on this would be greatly appreciated.

I've searched through my printed and pdf versions of the manuals and cannot find a pinout connector chart for the DL3 connector... Looks like TIS may be your solution. But here's the more specific HL system info on our cars.
Regrets,

Great find on the reset article, Habious!

Apparently there is a "no scan-tool needed dance" for resetting the AFS controller -- you know, one of those "press the switch eight times then open/close door three times" like we have to do when programming keys.

If anyone knows a dance for resetting the headlight leveling sensor ECU, that would solve the problem in a jiffy.

I think the XDA/CG info is either in oem repair manual volume 1 (more likely) or oem wiring diagrams manual, but I don't have the printed manual set with me right now.
