DIGITAL TELE AID CONTROL MODULE RETROFIT

WARNING:
Do not disconnect the negative battery cable. Extensive reprogramming requirements are otherwise necessary. Wiring harnesses are therefore electrically active. 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

1. Remove the analog Tele Aid control module and install the digital Tele Aid control module.

- See WIS document AR82.95-P-0005M, "Removing and installing TELE AID emergency call system control module"

NOTICE:
Incorrect installation of connectors can result in damaged, bent pins. Damaged, bent pins will result in component malfunction or failure. Inspect connectors before and after installation.

B. 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 via Star Diagnosis is necessary on Model Year 2003 V220.
