In Reply to: OBC Relay Box?? posted by Brian on February 03, 2002 at 17:09:57:
It was the OBC relay box.
This thing is not a "relay" like a regular square Bosch relay. It is a black box, roughly the size of 2 decks of cards. It is located to the left (driver's side) of the steering column. It is in a bracket, below a silver box.
It has 2 plugs going into the back of it. One plug has three wires, the other has 4.
The colors, etc. are shown on page 22-36 of the Bentley manual.
To bypass it, you splice together the green wire and the green/red wire. In searching the archives, I noticed someone had a way where you could find 2 connectors and plug them together to accomplish the same thing, but I could not find them and need the car by Monday (tomorrow). So I spliced.
Worked great!
I think this thing has been causing me an intermittent problem for about a year now. I'm glad to have it solved!
I guess it should be a suspect for a no-start condition.
Anyone know where that is located?
Also, it sends its signal to Prong 86 on the main relay, via a green wire. Is this 12V or a ground signal??
When I have my key turned to the accessory position, I have 12V at prong 30, but no voltage at any of the other prongs.
Thus, the car won't start. Anyone have any ideas??
