DIGITAL TELE AID CONTROL MODULE
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.

- Estimated Physical Installation Time: 0.7 h
- Opcode: 82-9621
A. PREPARING FOR THE INSTALLATION
- Read these installation instructions in their entirely before proceeding.
- Remove the rear passenger side seat cushion.
- See WIS document AR91.12-P-1020N, "Removing and Installing rear seat cushion"
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 under the rear passenger side seat cushion (Arrow, Fig 2). Lift up the protective covering under the seat cushion to access the control module.
- 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:
C. VERSION CODING
- 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 (on Model Year 03 cars) control module via Star Diagnosis is necessary.
- The "Tele Aid Defective" warning is displayed in the Instrument Cluster only when the engine is running.
D. POWER TRUNK CLOSING ASSIST (VEHICLES EQUIPPED WITH OPTION CODE 881)
- Perform a function check of the Power Trunk Closing Assist by depressing the button located in the trunk lid lip. If this function is inoperative, continue with steps 2 through 5 to resolve.
- Looking at the connector for the digital Tele Aid control unit (Fig 4), find pin 25 located in the bottom row on the far left. Once located count 8 pins to the right (using pin 25 as 1) and locate pin 32.
- Using a pair of needle nose pliers or similar tool remove pin 32 (Fig 4) from the digital Tele Aid control unit by simultaneously pulling and turning the pin.
- Once pin 32 is removed, verify that the power trunk functions normally.
- After the installation has been completed perform a RDU (remote door unlock) by calling ATX 1-800- 756-9018 and follow the operator's instructions.
