I was just wondering, Is there anything else usefull to do with these ports? There is a bunch of em, Or did they just do that to prevent us from doing our own diagnostic when the car was new? haha. I also got code 11, And i had my ground battery terminal come off, But i fixed that. Could it just be stored from that?

suprra_girl 07-20-2006 12:57 AM

yep from the ground cable

FP and B+ runs the fuel pump at 12v when ign is on
some cars have ect in theirs so you do ect & e1 = trans diagnostic
can't think of the rest for now lol

ok, i finally figured it out, took me like..10 mins haha so lame its been 3 months.
ok so its a 42...WHICH makes sense, cause my speedometer doesnt work, when i bought the car, the previous owner thought it was a speedo cable..but i guess not.

does anyone know if the sensor is in the transmission or is it behind the dash? what is a good way to test the sensor to make sure?

Did you get the trans. sensor issue straightened out yet? If not, I can help you.

I want to do a diagnostic but I dont know which ports I have to bridge. A pic would be helpful. And also how do you know what code number you getting. For example code 24 will blink 24 times?

Isphius 12-12-2006 07:03 PM

the pins you jump (t1 and e1) are pretty clearly marked on the cover to the diagnostic thing. Ones in the middle and ones on the top right. Code 24 will blink 2 and then 4 times. Like ...o.o...o.o.o.o...

redmaro 12-12-2006 07:11 PM

I know its e1 and t1 but, where is it on the diagnostic thing. My diagnostic thing dosent have a cover.

That white gunk is waterproofing/dielectric grease that helps keep water out of electrical connections, and it also helps to promote electrical conductivity.
