Autodocta – Mercedes-Benz Vito

VEHICLE: 2015 Mercedes-Benz Vito

ISSUE: We have a 2015 Mercedes-Benz Vito in our workshop with the SRS warning lamp illuminated, seat heating not working and several electrical related trouble codes stored. Have you any ideas where to start to fix this vehicle?

DIAGNOSIS & SOLUTION: We are aware of a SRS fault on Vito, V-Class and Valente models 2014 onwards. The fault is due to the front seat wiring harness chafing on the seat frame causing a short circuit. Inspect the front seat wiring harness for damage (fig.1.1.). Repair or replace the front seat wiring harness as necessary. Re-route the wiring harness to provide adequate clearance. Erase trouble codes and check operation of the seat heating to ensure the fault has been rectified.
