RPO Codes 2011 Avalanche

[David Smith]

Had a few questions about some codes inside the Avalanche that I am fixing. Maybe someone here may be able to help...

DCP - PROCESSING DIRECTIONS & CONNECTIONS SERVICE PACKAGE
Is this Navigation or something?

JL4 - CONTROL ACTIVE BRAKE
Is this trailer braking?

R7E - What is this?

R9N - What is this?

SLM - What is this?

UE1 - COMMUNICATION SYSTEM VEHICLE, G.P.S. 1
Is this part of DCP? Navigation?

6TK - COMPONENT-COMPUTER SELECTED SUSPENSION
Autoride or something?

7TK - COMPONENT-COMPUTER SELECTED SUSPENSION
Autoride or something?


Thanks for y'alls help!
