The BMW maintenance system Condition Based Service (CBS) monitors all systems necessary for operational safety. Sensors and special software programs determine the current and future maintenance requirements based on the vehicle operating conditions. This monitoring also includes wear of the brake pads at the front and rear axles. In order to ensure the fault-free function of the CBS system when calculating the brake pad thickness, the warning contacts of the brake pad wear indicator must also be replaced when replacing the disc brake pads.
The new brake pads and warning contacts must be communicated to the ECU. This takes place as the CBS maintenance scopes are reset.
Resetting can be carried out using a suitable diagnostic unit or manually on the instrument cluster.
Service reset using the example of a mega macs 66 diagnostic unit.
Follow the corresponding instructions for using the diagnostic unit.
The manual reset is carried out at the instrument cluster.
A reset is only possible if there are no Check Control messages and the on-board data is correctly set.
Wait until the time and temperature are displayed
If a reset is possible, this is displayed as 'Reset can be performed' (2)
In order to carry out a successful reset, the following must be noted.
In some cases, the reset with the respective diagnostic unit may not be detected by the ECU due to varying software statuses. In this case, a manual reset must be performed.
Please observe the maintenance and repair notes provided by the vehicle manufacturer.
