Validez: Automatic transmission 722.9 it is not possible to repair the EHS (VGS) in AMG vehicles
Motivo de modificacion: Note added: It is not possible to repair the EHS (VCS) in AMG vehicles
Reclamacion:
Automatic transmission 722.9 switches to limp-home while driving (gearshifts no longer possible) and/or one or more of the following fault codes
are stored or current:
For vehicles with VGS1
2200 2201 2204 2205 2206 2207
For vehicles with VGS2 or VGS3
0717, 0718, 0722, 0723, 2767, 2768
Causa:
Rpm sensor fault
Remedio:
Process the speed sensor fault codes completely using the DAS/Xentry guided test (possible as of DVD 01/2011 and add-on 1740). This may or may
not entail a replacement of the EHS.2010 Mercedes Benz Truck G 550 (463.236) V8-5.5L (273.963)

In the case of hardware replacement (when SDS instructs to do so, see attachment) the adaptation data of the old transmission control unit is read out
in the DAS/Xentry guided test and transferred to the new control unit after the repair. Subsequently, the transmission control unit, which is bolted
onto the electrohydraulic controller unit (EHS), may only be replaced using the EHS repair kit (A000 270 17 00) In other cases SDS will provide
alternate instructions
See also the Akubis direct film: "Replacement of "fully integrated transmission control" (VGS) controller unit at electrohydraulic controller unit
(EHS) on automatic transmission 722.9"
The VGS Control Unit (Control Module) only is to be replaced for VGS2 and VGS3 Control Unit versions with these fault codes, when SDS
instructs to do so VGS Control Unit is available as EHS Repair Kit (A000 270 17 00) Complete valve body "Electrohydraulic Controller Unit
(EHS)" replacement is necessary for VCS1 Control Unit versions when SDS instructs to do so. Control Unit Version is identified from the
Transmission Control Unit Log.
Note in Cases where hardware replacement is specified:
This procedure differs from a complete valve body replacement as the adaptation data, coding and valve body calibration data are transferred from
the old VGS Control Unit to the new VGS control unit This data from the old VGS Control Unit is stored in the Star Diagnosis unit by processing
one of the above codes. The same Star Diagnosis SW stem unit MUST be used to process the fault code and perform initial startup of the new VGS
Control Unit. Failure to do so will result in the necessary data not being transferred and improper transmission functionality after VCS Control Unit
replacement.
1. Process the speed sensor fault code completely by following the instructions in DAS/Xentry related to the fault code Note: During the
replacement of the VGS Control Unit it is imperative that the position of the solenoid valves are noted and re-installed in their original positions
Failure to do so will cause a mismatch in the calibration data to respective solenoid valve(s) and subsequent shifting complaints.
2. Replace the VGS Control Unit per WIS instructions For the initial road test following VGS Control Unit replacement the vehicle must be driven
gently for the first several shifts in each gear since it will be necessary to bleed the air from the valve body. Until the air is bleed out irregular
shifting will be noticed momentarily and will clear up with subsequent shift processes. Because the adaptation data is transferred from the
original VGS Control Unit performing subsequent shift adaptations is not necessary.

Battery - Battery Charging Information
Date: July 3, 2012
Order No.: S-B-54. 10/255
Group: 54
SUBJECT:
MY-All, All Models Charge Battery
Correct charging of the on-board electrical system battery, starter battery, and buffer battery helps to ensure that the vehicle continues to start,
functions properly, and has optimal battery life. Therefore please remember that all batteries >/= 12 Ah must be charged in the way described in
AR54.10-P-1130CW.
The battery charging period depends on the charge level of the battery.
The battery must be charged using an approved charger (see SSEP catalogue located under "MB Equipment" menu of STAR TekInfo).
The battery is sufficiently charged when the charging current reading is < 25 A. Technical

Complaint:
Different volume levels between AUX IN and radio or CD/DVD playback. During audio playback from an external MP3 player via the AUX jack,
the volume in the vehicle is too quiet. When switching from the AUX source to radio or CD/DVD the volume is too loud and must be turned down
by the customer. Traffic announcements are also too loud when an AUX audio source is active.
Cause:
The volume level of the MP3 player is too low.
Remedy:
Update the software in the head unit with DAS / Xentry Diagnostics.
Note:
As of the software releases listed below, the customer can choose between "Standard" and "Boost Mode" in the "Volume" menu in the AUX
application. In vehicles with SA code 518 [Media interface (N125/1)], software 08.47 is required in the media interface control unit (N125/1) for
this new function. This software update is launched automatically after the head unit software update.
