Safety Circuit & Monitoring Devices

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1995 Mercedes-Benz SL600, 1995 Mercedes-Benz SL500, 1995 Mercedes-Benz SL320, 1994 Mercedes-Benz SL600, and 1994 Mercedes-Benz SL500. However, it is still accessible from the selected car via links, so may be relevant.

There are 2 separate alternatives for deactivating the PML "P" valve (Y10) during fault detection by means of the monitoring devices and safety circuit. It is possible to shut off the valve from the positive and negative side. The monitoring device also checks the voltage supply. See VOLTAGE SUPPLY  .
