Operation number of operation texts and work units or standard texts and flat rates:27-0641Start test sequence.1. Erase fault memory.2. Perform a road test and switch the ignition off and on several times with the vehicle stationary.Continue check procedure.1. Once again read fault memory.Continue with button "F2"

REQUIREMENT

- The test drive recommended for this vehicle was performed.
Question:Is fault code P1875 present?

YES
Fault code 'P1875' presentPress button F2 for further tests

A customer complaint exists.If several fault codes regarding CAN communication have occurred, the following causes of the fault are likely

- Open circuit in voltage supply to the control modules involved
- Short circuit or open circuit of CAN wires
- Connector sleeves of the CAN bus
If CAN communication between control module N15/5 (Electronic selector lever module (ESM [EWM])) and at least one other control module is fault-free, there is no fault at the CAN element of the control module N15/5 (Electronic selector lever module (ESM [EWM])).In this case proceed as follows:

- Read fault memory of control module to which there is a fault in the communication.If a CAN fault regarding communication with control module ESM is present in this control module, then first of all test CAN lines between the two control modules.
End of test

NO
Fault code 'P1875' not presentNo additional tests are necessary.End of test
