A. Introduction

SCN Coding is required on Model 171 and 221 in order to replace the instrument cluster or to install certain accessories at the Dealer (i.e. Navigation, CTEL). This bulletin provides instructions on performing the SCN Coding for the instrument cluster. It is designed for ease of use and is similar to the SCN Coding instructions of other control units.

Because of the length of the Coding String, this bulletin also includes instructions on transferring the SCN Code to the vehicle via a new method. This new method involves burning the SCN Code onto a CD-R, and then inserting the CD-R into your STAR Diagnosis System (SDS). The SCN Code would then be transferred into the vehicle automatically. However, you will still be able to enter the SCN Code manually via the keyboard should you choose to.
