6/ CHILD SAFETY LOCK CONFIGURATION PROCEDURE (SC016)
This procedure will enable the child safety system, if fitted to the vehicle, to be configured for optimum running
during the replacement of a UCH.
–Click on the Repair mode and in the Programming menu,
–confirm the line SC016 Child safety,
–follow the procedure and enter the following data:
–CF104 Child safety lock (WITH or WITHOUT),
–confirm and follow the procedure,
–finish by confirming and clearing the stored faults. The child safety function is configured.
