was not followed
Wrong code was entered
The -E87 is coded for a vehicle with‐
out map-controlled cooling and a re‐
sistance smaller than 100 kilo-ohms
is measured at the inlet for sender -
G191 (connector B, contact 6).

Basic setting not performed
- Either a fault occurred during the "ba‐
sic setting" function, or the ignition was
switched off and -E87 was not able to
complete the function.
When -E87 was replaced, no basic set‐
ting was performed.
The basic setting was performed on an
-E87 that was incorrectly encoded or
not encoded at all
- Check the coding of operating and dis‐
play unit -E87 =>Page 24

Signal for ignition off time 1)
* Implausible signal /SP
- Open circuit or short in wiring between
dash panel insert and -E87.
Dash panel insert defective.
- Use current flow diagram to locate and
eliminate short circuit, open circuit in
wiring or fault in pin assignment.
Checksignal from dash panel insert (=>
Reading measured value block, Page
31 ).
1) If, when the ignition is switched on, no "ignition off time" signal is detected by the operating and display
unit -E87(transmitted by the dash panel insert), the -E87 assumes a standing time of more than 4 hours and it
is assumed that the engine temperature is the same as the ambient temperature. In heating mode, the fresh
air blower may thus have a delayed start despite the engine being warm. Ambient temperature indicator -G106
in the dash panel insert may also display incorrect ambient temperature values.
