Description

Time signal 'Day' within the CAN message 'Time/Date' faulty (CAN SPN 962).

Effects on the driving operation

Possible causes

An incorrect value for 'Day' within the CAN message 'Time/Date' was received via the CAN bus (CAN SPN 962).

With software version D2.3.0.0:

With this version of the transmission control unit software, the message occurs on the 1st of each month.

The reason is a wrong calculation of the day number. This has no effect on the driving operation and can be ignored. Some of the time flags in the event memory might be set incorrectly.
