Validity adapted. Remedy adapted.
Intermittently after the COMAND Online (A40/3) or Audio 50 (A2/56) or Audio 20 (A2) control unit has booted up, the Audio/COMAND display (A40/8) may show the fault message "Anti-theft protection activated. Please visit your Mercedes-Benz workshop" (see attachment for examples). The fault code 9561 "The PIN for the anti-theft protection is incorrect or absent" is current and/or stored in the quick test of XENTRY Diagnostics in the COMAND Online (A40/3) or Audio 50 (A2/56) or Audio 20 (A2) control unit. When the complaint is active, the COMAND Online (A40/3) or Audio 50 (A2/56) or Audio 20 (A2) control unit cannot be operated .

Cause: CAN communication wi th motor electronics control unit (N3/9).
Remedy: ill. Check of glow time output stage (N14/3) by means of voltage test: Important: There are two different connector variants, 8-pin (without fuel-filter heater) and 10-pin (with fuel-filter heater); the pin assignments of the glow time output stages can be found in the attachment. 1. Remove glow time output stage (N 14/3). 2. Apply 12 V to circuit 30 and circuit 31 of glow time output stage (N14/3) (e.g. from on-board electrical system battery). 3. Measure voltage between circuit 15 (without fuel-filter heater) or 87 (with fuel-filter heater) and circuit 31 of glow time output stage (N14/3) using a multimeter. The glow time output stage is defective if the multimeter indicates a voltage greater than approx. 1 V. If this test confirms that the glow time output stage (N14/3) is defective, it must be replaced. If the issue in the glow time output stage is not confirmed, perform remedy b). 121 Please perform the following work: - Check circuit 30 pin in connector "F" (2) of motor electronics control unit (N3/9) for voltage, expansion of pin and corrosion.

- Check chassis CAN (high and low) pins in connector "F" (2) of motor electronics control unit (N3/9) for expansion of pin and corrosion. Causes identified to date include e.g.: - Pin of circuit 30 in connector "F" (2) of motor electronics control unit (N3/9) not clipped in at connector housing (cf. attachment "Circuit 30 pin.jpg"). - Pin of ci rcuit 30 in connector "F" (2) of motor electronics control unit (N3/9) or in control unit itself corroded. - Connector in front SAM control unit (connector 41), which supplies the motor electronics control unit (N3/9) with cir-cuit 30(z) and chassis CAN, was not clipped in correctly (refer to wiring diagram in WIS for pin assignment). - Wiring harness was chafed under the wiper linkage (cf. attachment "Figure 2a.jpg" and "Figure 2b.jpg"). -> 12V was measured in the vo ltage measurement at the pin of circuit 30 in connector "F" (2) of the motor electronics control unit (N3/9), but this voltage collapsed under load. If no noticeable problems are found here, perform remedy c). g Perform the test procedure described in the attachment. If this cause the theft protection to activate, replace the motor electronics control unit (N3/9). If the complaint still exists after replacement of the engine control unit, perform remedy d). Q} Create a TIPS case containing the following data : current quick test and current control unit log for COMAND Online (A40/3) or Audio 50 (A2/56) or Audio 20 (A2). J.rru:lortant: Always use the damage code of the part causing the damage! Note: Replacing the COMAND Online control unit (A40/3), the Audio50 control unit (A2/56) or the Audio20 control unit (A2) does not remedy the problem.

Testablauf (auf dem Fahrerplatz sitzend): (Die Punkte 1 und 2 sind keine Alternativen sondern nacheinander durchzuflihren)
1. Fahrzeug in Busruhe bringen: >- alle Tliren schlieBen Y Schlusse l aus dem EZS (N73) abziehen >-- ggf. Warnmeldungen auf dem Kombiinstrument quittieren >-- Fahrertur offnen und gleich wieder schlieBen >-- warten bis sich das Kombiinstrument abschaltet >- weitere 30 Sekunden warten
2. Start ohne Zundung: Y Head Unit uber den ON-Button starten );:> Schlussel in das EZS (N73) stecken );:> Schlussel auf erste Raste drehen (ACC, Klemme 15R) >-- 30 Sekunden warten
Falls das beschriebene Fehlerbild vorliegt, erscheint im Audio/ COMAND Display (A40/ 8) die Fehlermeldung "Diebstahlschutz aktiv" .
Gegenprobe: Die oben beschriebene Sequenz wiederholen, jedoch unter .,2 . Start ohne Zundung" den Schlussel sofort auf die zweite Raste drehen (IGN, Klemme 15). Die Fehlermeldung "Diebstahlschu tz aktiv" so llte in diesem Fa ll nicht erscheinen.
Test procedure (sitting on the driver's seat): (Points 1 and 2 are no alternatives but to carry out one after another)
1.
