Where Are Diagnostic Connectors?

looking for the diagnostic connectors so I can read a CEL from my 2005 LGT.

Near the driver's left leg, under the dash

Pop the fuse cover, and dig in deep. It's very well hidden and very well taped to the other harness.

There is no need to pop the fuse cover, it is just behind the fuses cover and easily reached.

 

BTW, very odd that the OBD interface location is nowhere mentioned in the owners manual. Took me awhile to find it.

Just look under the dash in the drivers footwell, can't miss it.

ok after I connect them how do I check for codes?

There is a green and white male plug and white female plug up there. Connect the two white female plugs and as the guages sweep, press the trip reset button. The code is in fact displayed on the odometer.

connect them? if your referring to the the two green plugs in the front passenger foot well those are for putting the car in test mode for reading and writing to the cars ECU for ROM updates and tuning.

 

OBDII plug is on the left side the driver foot well and an OBDII scanner would be needed.

If you want to check a code, there is a series of buttons to push in the car to check the code w/o a scanner I think this is it...

 

Turn key to accessory

Before the needles do a full sweep, turn parking lights on (1 click on lights)

click trip button 3 times

parking lights off

trip button 3 times

parking lights on

trip 3 times

 

I think you just do it three...then the code shows up on the odometer. Search it in this site and you'll find the post of all CEL codes

^ that sounds more like a cheat code for a Nintendo than a diagnostic procedure. I bought a cheap code reader, but your method sounds more entertaining!

ha ha yeah I didn't believe it worked and then...voila!

 

I still play my N64...often. My wii has old nintendo and sega games on it too ohh the 90's
