7.2 Diagnostic with Button and Error Code
With the diagnostic button there is the possibility of reading out the existing faults as blink codes and to
delete the fault memory 1. The Diagnostic button and the fault indicator lamp are situated in the moving
part of the vehicle.
7.2.1 Reading out a current fault memory blink codes
The fault indicator lamp shows a fault, e.g., it flashes or lights continuously. The Diagnostic button is
depressed for a time period of 1 s to 3 s. The EMR 2 recognizes the request for a read out and starts to dis-
play the faults. (see blink code overview, Chapter 7.2.3). The read-out of the blink code is only possible after
extinguishing of fault indicator lamp or after the initialization phase of the operating program. This means
that the fault indicator lamp can also show continuous lighting after switching on if a fault has been recogni-
zed already after switching. The EMR 2 only shows
active faults as blink codes.
In the following the steps for reading out the first blink code are shown:
a The fault indicator lamp indicates a fault, e.g. it flashes of lights continuously.
