Programming

GS 20 Programming:

The control module must be programmed to update resident program data in an existing or after replacing a defective GS 20 control module. As with previous systems, the fault memory must be cleared and the system fully functional.

Connect a battery charger to the vehicle prior to programming to ensure adequate voltage supply during the programming procedure. When programming is completed, clear the system adaptation values using the DIS or MoDiC.

Always make sure the programming software is the latest version.
