Programming Gateway Control Module

Information 

• If the gateway control module is replaced, the gateway control module must be programmed or coded with the PIWIS tester. This is to adapt the Gateway control module to the vehicle and equipment. 
• Before the gateway control module is removed, the vehicle data should be read out with the PIWIS tester if possible. 
• If reading out the data is not possible, the new gateway control module must be coded. → Removing and installing gateway control module - coding 
• The power supply for the PIWIS tester must be ensured while reading out the data. It is essential to connect a battery charger with a current rating of at least 40 A to the vehicle battery. 
• The PIWIS tester instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
