INSTALLATION OF CD CHANGER AND CELLULAR TELEPHONE (CTEL) SYSTEMS
The Work Instructions (W.I. nos. 399 through 408) describe the installation of the CD changer and cellular telephone (CTEL) in model 129, 170, 202, 208 and 210 vehicles as of Model Year 1999. Copies of the cellular telephone NAM programming guide and authentication programming instructions are also included in this SI.
Refer to the following pages for the diagrams of fiber optic (D2B) cable connections and some general notes.
The fiber optic cables (D2B) are easily identified as having brown, rigid insulation. The fiber optic cables for the CD changer and/or cellular telephone installations are loosely prewired along vehicle electrical harnesses. These digital data bus cables are lighter than conventional electrical wires, transmit more information and are not influenced by surrounding electrical and magnetic fields (noise reduction).
The fiber optics however, are more susceptible to physical damage.
Warning:
Handle fiber optic cables (D2B) with caution. Make sure they are not pinched, bent, nicked or stretched.
Damaged D2B cables will cause system function problems.
Note:
The transfer of units from one vehicle to another, voids the warranty.
The system components connected by D2B fiber optic cables create a closed loop or ring. If only a CD changer or telephone are installed, the fiber optic loop is closed between radio (head unit) and CD changer or telephone (Portable Support Electronics - PSE module) respectively. To install both systems together, the fiber optic (D2B) ring or loop must be opened, an additional fiber optic jumper cable (provided with the telephone installation kit for models 129, 208 and 210 only) installed and the fiber optic loop connection reconfigured. Refer to following pages for the connection diagrams.
To open the fiber optic loop locate the in-line optical junction or splice (see Figure 1). Open both sides of the splice by prying up on the end of the metal retainer clips. Remove the fiber optic cable ends with lenses by pulling gently out of the splice connector. DC) NOT BREAK THE RED OR CLEAR LENSES OFF THE CABLE.
Each component in the fiber optic (D2B) loop is connected through a 2-cable fiber optic end connector (see Figure 2) with a clear and red lens respectively. Reconfiguration car be accomplished by opening an optical junction or the optical end-connector.
Note:
1. Each device is connected through a two-lens connector with attached fiber optic cables. The optical fiber with a CLEAR lens sends the output signal and the fiber with RED lens receives the input signal at each device.
2. The red lens is always placed next to the chamfer in the optical fiber connector.
3. When connecting the CD changer and phone, the CD changer is always connected "first" in the loop.
4. When installing the phone and CD changer, follow the connection diagrams and procedures in respective Work Instructions.
5. Cable ends and optical fiber continuity can be checked by shining a light into one end of the fiber and observing for light at the other end.
The next pages show simplified schematic diagrams of the fiber optic cable (D2B) connections. The optical splices, the unused portion of the fiber optics or optical jumper cables are not shown.
A. Fiber optic cable (D2B) connection diagrams for CD changer, cellular telephone and combination of CD changer with the cellular telephone (except model 170)
B1 Fiber optic connections for combination CD changer and cellular telephone - model 170 (SLK).
Installation notes:
1 If CD changer and phone are installed: the fiber optic loop goes from the radio to the CD changer to the cellular telephone (Portable Support Electronics module) and back to the radio.
2 Most of MY '99 model 170 vehicles should be prewired at the factory in this configuration. The additional fiber optic connector (Connector A) is not used in this configuration. Additional fiber optic cables (not shown on the diagram) are also not used.
3 The fiber optic cable between the CD changer and cellular telephone (PSE module) runs from the left to the right side of the trunk near the retractable cargo cover.
4 The fiber optic cable with red lens is always on the chamfered side of the connector. The clear lens is the output and red is the input.
B2. Fiber optic connections for CD changer - model 170 (SLK).
Installation notes:
1. If only the CD changer is installed: the fiber optic loop goes from the radio to the CD changer and back to the radio. Connector A at the radio must be used.
2 The fiber optic connector (Connector B at the radio) is not used in this configuration. Additional fiber optic cables (not shown on the diagram) are also not used.
3 The fiber optic wire with red lens is always on the chamfered side of the connector. The clear lens is the output and red is the input.
B3. The fiber optic connections for cellular telephone (CTEL) model 170 (SLK).
Installation notes:
1. If the cellular telephone (CTEL) only is installed: the fiber optic loop goes from the radio to the telephone (PSE module) and back to the radio. Connector B at the radio must be used.
2 The additional fiber optic connector (Connector A at the radio) is not used in this configuration. Additional fiber optic cables (not shown on the diagram) are also not used.
3 The fiber optic cable with red lens is always on the chamfered side of the connector. The clear lens is the output and red is the input.
