Installing Optical Waveguide (PCM to Loudspeaker Amplifier)

Installing Optical Waveguide (PCM To Loudspeaker Amplifier)

Information

MOST control units A - B:







Preliminary work

INFORMATION: Release the main wire harness only until the damaged optical waveguide has been released and the new optical waveguide can be attached to the main wire harness.

1. Remove dashboard.
2. Remove loudspeaker amplifier.

Installing optical waveguide (PCM to loudspeaker amplifier)

Disconnecting optical waveguide

NOTE:
Voltage peaks
- Risk of damage to load or to the control unit

- Remove the ignition key and switch off load before disconnecting or removing load.

INFORMATION: Observe the general information on optical waveguides.

INFORMATION:
Before routing a new optical waveguide:
- Visually check the locks, connector housing and contacts for damage.
- Replace damaged parts if necessary.

1. Release and unplug the optical waveguide connector at the loudspeaker amplifier.







2. Release and unplug the optical waveguide connector at the PCM system.







Installing optical contacts on connector side

Remove the dust boot right before plugging.

Check the proper condition of the contacts.

1. Insert the optical contact -A and B- in the connector until it engages audibly.







2. Lock the secondary locking and check the optical contacts for tightness.

NOTE:
Voltage peaks
- Risk of damage to load or to the control unit

- Remove the ignition key and switch off load before disconnecting or removing load.

INFORMATION:
- The new lines will be secured to the fastening points for the old lines.
- The new lines will be secured to the fastening points for the old lines.
- The old wire harness will only be disconnected/unplugged directly at the connected components.
- When installing the wire harness, make sure the insulation of the line is not damaged.

The range of spare parts available for optical waveguides depends on the vehicle equipment. Depending on the vehicle equipment, there is a specific set containing the individual optical waveguides.

Select the required optical waveguide and remove it from the set.

INFORMATION:
Before routing a new optical waveguide:
- Visually check the locks, connector housing and contacts for damage.
- Replace damaged parts if necessary.

1. Cut off the optical contacts of the damaged optical waveguide, isolate it and tie it to the main wire harness.
2. Route the new optical waveguide along the main wire harness, guide it through the existing cable ducts and tie it to the main wire harness using tie-wraps (shown as an example).







3. Plug in the optical waveguide connector at the loudspeaker amplifier and make sure that the locking mechanism engages securely.







4. Plug in the optical waveguide connector at the PCM system and make sure that the locking mechanism engages securely.







Subsequent work
1. Install loudspeaker amplifier.
2. Install dashboard.
