SERVICE INFORMATION
Severe vehicle damage, personal injury, or death from electrical shock could result.
Exercise extreme caution while executing these installation instructions. Keep the ignition and radio powered OFF through the final test.
Notes on D2B 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 D2B optical fibers by their orange, semi-rigid insulation.
- Electromagnetic interference (EMI) from bundled vehicle electrical harnesses does not affect optical fibers.
- The digital Tele Aid control module for vehicles equipped with ECALL2 has a D2B port. Do not connect the D2B port of the digital Tele Aid control module if the existing analog Tele Aid control module has no D2B port. Include the digital Tele Aid control module in the D2B ring configuration only if the existing analog Tele Aid control module has a D2B port.

A. RETROFITTING THE DIGITAL TELE AID CONTROL MODULE
- Read these installation instructions in their entirety before proceeding.
- To get access to the unit, see WIS document AR82.95-P-0008GH, "Remove/install control module for E-Call emergency call system" (do not remove the unit at this point).
B. RETROFITTING THE DIGITAL TELE AID CONTROL MODULE
- 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.
- Remove the analog Tele Aid control module from beneath the right, front seat (Fig 2) by removing the screws (Arrows, Fig 3).
- Disconnect the cables from the analog Tele Aid control module:
- Install the digital Tele Aid control module using the previously removed screws.
- Connect the cables to the digital Tele Aid control module:
- GPS Antenna connector (A, Fig 3)
- Power supply connector (B, Fig 3)
- D2B connector, if applicable (C, Fig 3)
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.
