Hi,

I posted in the engine section before, but i believe that someone in this
section may knows the answer...

Last sunday we wanted to run the DIACOM.
This is fine, because you can see EVERYTHING the ECM does on the laptop.
Since i have the codes 44+45; lean AND rich o2 sensor, we wanted to
know WHY...
But the cable couldnīt get any data ? It worked fine on the ī88 GTA.
I found out that the aldl ports pins differ...

My brougham:

(-) ( ) (-) (-) (-) (-)
( ) ( ) ( ) ( ) ( ) ( )


My friendīs 88 Pontiac Trans Am GTA w. 5 Speed:

( ) (-) ( ) (-) (-) (-)
(-) ( ) ( ) ( ) ( ) (-)


Iīm confused; why does my caddy not have the diagnostic pins E and/or M ??

Does my caddy use other port/s for communication with an ALDL cable??

...hmmm, unfortunately nobody here knows the answer?

Maybe it would help me to know, if the ALDL Ports Pins in your Fleetwoods / Broughams do look the
same as mine posted above.

Thank you very much.


(rich, lean, rich, lean... grrrr... I want to see what the ecm does on the laptop... grrrr...)
