Dynamic Stability Control MK60 and MK60E5

Dynamic Stability Control Mk60 and Mk60E5

The DSC Mk60 is fitted on vehicles with 4-cylinder engines.
The DSC Mk60E5 is fitted on vehicles with 6-cylinder engines.
A variant of the DSC Mk60E5 is fitted in the E60 M5. This variant is adapted to the M5 / M6.

Sequence for replacement of the DSC unit or DSC control unit (DSC MK60 and DSC MK605E)
After replacement of the DSC unit or of the DSC control unit, the following work is to be performed in the following order:
1. Encoding DSC On code the DSC, vehicle-specific data records are selected (e.g. size of the brakes). At the same time, the data for encoding for the steering column switch cluster is stored and transferred across the F-CAN to the SZL (not on the M5/M6). This means that if the SZL is renewed the DSC control
unit also has to be encoded. Without successful encoding, no adjustment of the steering angle sensor is possible. Even if there are faults in the DSC, encoding is normally possible.
2. Adjustment of steering angle sensor The zero point of the steering angle sensor, the vehicle identification number and the serial number of the SZL are stored.
3. Adjustment of DSC unit MK60: The internal brake pressure sensor is adjusted.MK60 E5: The internal pressure sensors and the valves (characteristic curve for the flow rate) are adjusted. The internal longitudinal acceleration sensor (not M5/M6) is adjusted.
In the event of faults that affect the valves or pressure sensors, the adjustment might not be possible.
4. Brake bleeding procedure for DSC unit
5. Mix-up test, brake lines
6. Initialise Run Flat Indicator (see operating instructions)

Replacement of DSC sensor
After replacement of the DSC sensor, the service function "Adjustment DSC sensor" must be run. The lateral acceleration sensor or lateral acceleration sensors are adjusted in the DSC sensor.

Replacement of steering angle sensor
The steering angle sensor forms a unit with the steering column switch cluster. It cannot be renewed alone. The service function "Adjustment steering angle sensor" or in the case of vehicles with active steering the service function "Commissioning/aligning active steering" must be run after the following work:
- Replacement of steering column switch cluster
- Encoding of the DSC control unit or encoding of the SZL
- Replacement of DSC control unit
- Adjusting procedure on the steering geometry
- Work on the steering and/or front axle

General notes on DSC MK60
An internal brake pressure sensor replaces the two brake pressure sensors on the main brake cylinder. This brake pressure sensor cannot be renewed separately.
The hardware and software of the control unit have been adapted to the vehicle circuit structure.

General notes on DSC MK60 and DSC MK60E5
The software of the control unit can be updated when required by authorised dealerships in compliance with strict security and procedure rules.
For Condition Based Service, the brake pad wear is determined by the DSC control unit. The brake pad wear sensor are therefore designed in two stages. One sensor per axle. On the M5 and M6, two sensors are fitted for the front axle and one sensor is fitted for the rear axle.
Faults in the steering column switch cluster (SZL) are sent across the F CAN to the DSC and stored in the DSC control unit. As of 12/04, when encoding the DSC the encoding data for the SZL is transferred across the F-CAN.
The SZL is encoded in this way.
The control unit functions for the SZL can be called up via the DSC control unit.

General notes on DSC Mk60E5
The DSC unit contains 5 internal pressure sensors and valves with variable characteristic curves for the flow rate: so-called "analogised" solenoid valves. The characteristic curves for the flow rate must be learned (calibrated). A longitudinal acceleration sensor is integrated on the printed circuit board of the control unit (not M5 and M6). M5 and M6: the longitudinal acceleration signal is transferred from the gearbox via the PT CAN to the DSC. The version of the DSC sensor for vehicles with active steering delivers redundant signals (2 for yaw rate, 2 for lateral acceleration).
The control unit has been completely revised and contains new functions:
- Drive-off assistant
- Brake standby
- Dry braking
- Increase in the brake pressure on fading
- Soft stop

Note on M5 / M6:
The E60 M5 has a steering column switch cluster with its own diagnosis address. The fault entries and control unit functions for the SZL are therefore evaluated directly in the SZL and not in the DSC (same as E60). This means that after replacement of the SZL no encoding of the DSC is required.
