SERVICE INFORMATION

Notes on MOST optical fibers

• Optical fibers damage easily-handle optical fibers with care to prevent cuts, nicks, abrasions, and crushing.
• Optical fiber "ring configurations" must form a closed loop to function (i.e. couple the input of a component with the output of the preceding component).
• Identify MOST optical fibers by their orange, semi-rigid insulation.
• Electromagnetic interference (EMI) from bundled vehicle electrical harnesses does not affect optical fibers.

A. PREPARING FOR THE INSTALLATION

1. Read these installation instructions in their entirety before proceeding.
2. Remove the rear seat cushion.
   • With CODE (223b) - Electronically adjustable rear bench seat
     • See WIS document AR91.12-P-1020M, "Remove/install rear seat cushion"
   • With CODE (224c) - Electronically adjustable rear single seats, with seat ventilation, seat heater and memory package
     • See WIS document AR91.12-P-1020MB, "Remove/install rear seat cushion"
   • Except CODE (223b) and CODE (224c)

B. RETROFITTING THE DIGITAL TELE AID CONTROL MODULE

1. Leave the analog Tele Aid control module installed to perform this step. Exchange the analog Tele Aid control module with the digital Tele Aid control module only when prompted by Star Diagnosis. 

   For automatically version coding the Tele Aid control module, select in Star Diagnosis:

   Control units > Information and communication > Audio, video, navigation and telematics > Tele Aid > Initial Startup > Initial Startup with automatic takeover of settings of previous control unit  or, for manually version coding the Tele Aid control module, select in Star Diagnosis:

   Control units > Information and communication > Audio, video, navigation and telematics > Tele Aid > Initial Startup > Initial Startup with manual settings input for new control unit 

   See Section C, to better understand how the manual and/or automatic replacements have to be completed in Star Diagnosis.

2. Disconnect the cables from the analog Tele Aid control module:

   2. Antenna connector (B, Fig 4)
   3. Power supply connector (C, Fig 4)
   4. Power supply connector (D, Fig 4)
   5. MOST connector (E, Fig 4)

4. Install the digital Tele Aid control module using the previously removed three M5 nuts.
5. Reinstall the bracket for the Tele Aid control module using the previously removed M5 flange nuts (Fig 3).
6. Connect the cables to the analog Tele Aid control module:
   1. GPS Antenna connector (A, Fig 6)
   2. Antenna connector (B, Fig 6)
   3. Power supply connector (C, Fig 6)
   4. Power supply connector (D, Fig 6)
   5. MOST connector (E, Fig 6)
      Fig 6: Digital Tele Aid Control Module Connections

      
      NOTE: Incorrect installation of connectors can result in bent pins.

      Bent pins will result in component malfunction or failure.

      Inspect connectors before and after installation.

C. VERSION CODING

1. The retrofitted digital Tele Aid control module is not activated. Activate the digital Tele Aid control module by following the Preliminary Draft of "DAS Procedure - Digital Tele Aid Control Module Retrofit" posted on Star TekInfo.

   Also see posted on Star TekInfo  , the Preliminary Draft of "MMI Overview - Digital Tele Aid Control Module Retrofit"

   NOTE:

   • Tele Aid version coding the Instrument Cluster and Central Gateway (ZGW) via Star Diagnosis is necessary.
   • Version Coding the head unit is necessary and has to be correctly set via Star Diagnosis: Tele Aid "Not Fitted" for CP TeleAid MY04, and "Fitted" for LCT TeleAid MY05/06
   • The engine must be running for the "Tele Aid defective" warning to display in the Instrument Cluster.
   • If during Service Call the operator reports he can not hear anything in the vehicle, the Voice Recognition control module (SBS) should be replaced, even if no error DTCs are detected in the SBS. The discrete micro bypass function to the TeleAid of this control module sometimes fails. The normal hands free telephone works fine though. Also the discrete micro array should be checked.
