Signal Description, Rear Electronic Module (REM)






Signal specification

Rear electronic module (REM) connectors A-E




Connector A, terminals #A1-#A20
The following values are measured between the relevant terminal and terminal #E1 (power ground) unless otherwise stated.
The values are measured with the control module in "Active mode".

Note! It is important to connect the breakout box and check the ground terminals before taking readings.

U = DC in volts (V).
Ubat = battery voltage in volts (V).
Ulow = Voltage close to 0 V.
NC = Not connected
NC* = grounded via capacitor (C=22nF)













The power signals below are measured between the relevant terminal and terminal #E1 (power ground)





Resistance values, fuel level sensor




Readings for the left fuel level sensor are taken between terminals #5 and #6.
Readings for the right fuel level sensor are taken between terminals #7 and #6.
The following table lists the fuel level sensor resistance and the corresponding fuel volume.
