I have finally decided to get the rpo codes for my car, I was wondering what these ones were though, since they don't come up in the decoder

E5Z : SPEEDOMETER ADAPTER (DELETE)
Unable to locate code E7Z in our database!
E9Z : SPEEDOMETER KEY (DELETE)
Unable to locate code D7G in our database!
MM5 : MERCHANDISED TRANS, MAN 5 SPD PROVISIONS
YT1 : BUILD UP DR & QTR

Unable to locate code 629 in our database!
Unable to locate code Z31 in our database!
Unable to locate code ZF8 in our database!
Unable to locate code W82 in our database!


THe speedometer adapter and key delete? what is it?
mERCHANDISED TRANS, IS THIS JUST 5 spd?

Also I will probably have more questions when I get the rest (didn't have a big enough piece of paper)

Thanks

 

I was actually wondering the exact same thing!!! I made a post about it too. Does anyone know?

 

it also said I had some computer controlled alarm system??? I have NOTHING

 

E7Z : SENSOR, VEHICLE SPEED (DELETE)
Z31 : ADVANCE PRICE SHEET

Lots all I found, don't know if they are totally accurate, couple sites around describe different things for same RPO.

629 or what ever it is is probably an interior color.

 

What exactly is the vehicle speed sensor delete? What does it do?

 

Nah wouldn't be interior color I found that one. Unless they got two

Thanks for the info, now I gotta wonder, What the hell is it?
This is really getting on my nerves, there is no infor ANYWHERE

 

I just thought and figured out, vehical speed sesor delete is if you have a cable driven speedo. Lol me smart, after thinking for a long time

 

there were 3 codes for the interior, 1 of them was the seatbelt color. thats the way mine came up
but i can't find these codes
R6V
1SZ
R8T

the first one is on a camaro z28 (91)
and the 2nd two on a 92 rs

oh, and i think the speed sensor delete was for vehicles capable of more than the 110 governed speed that's my guess

and the mm5 is part of the 5speed code my t-5 rs has an m39 specifying which man. trans. is that what yours is

 

could be for the VATS (vehicle anti-theft sys.) is yours a 89-92, this might be it, or yours had keyless entry when new but the key fobs got lost somewhere between owners

 

Mines an 85 camaro anti theft system no, keyless entry, did they have that? What would I need to look for in order to be sure?
