Charge indicator lamp, exterior lamp failure

Terminal 61 is used for the generator 
indicator lamp. When the ignition is
On the excitation voltage is applied to it and 
the generator voltage when the engine is 
running. 
However, a terminal is required for some 
systems (e.g. exterior lamp indicator) which

D

is exactly at ground potential (low level), 
when the engine is not running with the 
ignition On

D

is exactly at least 10.5 V (high level), 
when the voltage at terminal 61 
exceeds a particular voltage or the 
engine speed exceeds a particular 
threshold (480 rpm). 

Terminal 61e is used for this (engine running 
recognition/speed threshold value).
Terminal 61e is produced in instrument 
cluster (A1) in accordance with the sketched 
circuit diagram:
An electronic system is ...via terminal 15

Terminal 61 and the speed signal are used as input signals which 
reach the instrument cluster via the CAN data bus.
If a particular speed or a particular voltage threshold at terminal 61 is 
exceeded, the transistor switches off and terminal 61e goes to high 
level (terminal 61 and the speed signal are interlinked to terminal 61e 
via an OR function. Also refer to table.)

The maximum current at terminal 61e is approx. 2 mA at high level 
and approx. 350 mA at low level. The switching delay is 
0.5 seconds in each case.

Exterior lamp indicator lamp and charge indicator lamp
The input signal of terminal 61 and the speed signal are used for 
engine running recognition. Depending on these input signals the 
exterior lamp failure indicator lamp (A1e14) or the generator charge 
indicator lamp (A1e5) is actuated (refer to table).

The instrument cluster also passes on the status of terminal 61e as a 
CAN message. The information is consequently available to all bus 
participants. 
On models 163 and 168 terminal 61e is only made available as a 
CAN message. There is no discrete terminal 61e line.
