DIS v44: Diesel Injector Coding / Programming Guide

If an injector is replaced it needs coding to the ECU. Once you know what to do, injector coding is a pretty quick and easy job, all 6 can be done in about 15-20 minutes. You will need a working install of DIS and EDIABAS, so a download and setup-guide is in this post. The code is 6 or 7 digits and printed on the top of each injector, more information in this post.

** Connect a float-charger to the battery before coding with DIS ** The process takes 10-20 minutes if all goes well, but it is not worth the risk of doing adjustments to the ECU without one.
