EMF Self Diagnostics

EMF Self Diagnostics

The self diagnostic functions are divided into several modes. These modes are executed in priority for diagnosis. When the vehicle is stationary and self diagnosis is being executed, the parking brake function is fully operational. Fewer diagnostic modes are allowed while the vehicle is moving. A self diagnostic mode that will restrict or completely deactivate the parking brake function is executed only when the vehicle is stationary.

Certain faults in CAN communication will cause the manual emergency mode and the Automatic Hold will not function. The "manual level" is operational and the parking brake will still be applied and released by the EMF or DSC when the push button is pressed with the vehicle stationary. Dynamic Braking also remains available. The loss of the Automatic Hold function is indicated only with the variable parking brake indicator lamp.
