Customer states:

* — Awarning or malfunction is present.
Workshop findings:

* — Awiring issue is identified as a root cause.

Technical Background

During service, a wiring issue is diagnosed as a root cause of failure. When reviewing warranty claims critical
information describing the symptoms, findings, circuit affected, and location of the damage is often unclear.

We are requesting your assistance in identifying and documenting wiring repairs. This helps identify common repairs
and improve product designs.

Production Solution

Not applicable.

Service

Once a wiring issue has been identified we ask for your cooperation in documenting the findings and taking photos
of the damage found. Please upload the photos as described below to DOC-IT.

For root causes relating to pins or coaxial connector ends:

* Retain approximately 10-20 mm of the original wire where space allows.

* Repair connection using VAS1978B

For root causes relating to high resistance or a short circuit in the wiring:
* Overlays may be used for diagnosis.

* Retain the affected section of wire that was removed/faulty.

* Repair faulty sections of the wire using VAS1978B.

In the technician’s notes please include the following details:

— Circuit affected.

Pin identification of the main circuit affected.

Circuit checks made including any resistance and/or voltage values of the affected circuit.
Location of where the damaged pin or circuit is found.

Any other relevant details to support and describe the findings.

Example: Flexray circuit measured .6 ohm to ground with no components connected to the circuit. Short circuit to
ground present on the green FlexRay wire between J743 Dual Clutch T23/1 and J533 Data Bus on Board
Diagnostic Interface T54/27. Located damaged wire section underneath the driver seat along the frame rail.

Photos are needed for accurate location and findings:

* 1 perspective view — Shows general area and provides a reference of the surrounding area (Figure 1).
« 1 original routing — Taken before the area of concern is disturbed (Figure 2).

* 1 close up — clearly focused and showing the damaged circuit (Figure 3).

Photos should:

* Have a date stamp and VIN reference.

* Be taken in focus and with sufficient light.

Perspective view:

Using the description in the example above, the root cause can be clearly identified in Figure 1.

Figure 1. A perspective view showing the area along the frame rail.

Routing concerns:

When a harness routing is determined to be the root cause, a photo should be taken to show how the harness was
routed in its normal state (Figure 2).

Close-up:

Using the description in the example above, the damage to the FlexRay wire is clearly visible in Figure 3.

No Technical Assistance Case (TAC) case: Upload photos to DOC-IT.

TAC case present: If a case is made before or after a wiring issue is identified, please update the TAC case with all
information and photos described above.

Warranty

When claiming wire repairs often times PID 9709 is used as a default PID. Using the correct PID helps to
differentiate which harness is affected.

The table below lists examples of PID’s to help claim repairs in specific locations. Please see the damage code
catalog in Elsa for a more comprehensive list, Elsa >> damage code catalog >> Electrical >> 97 Wiring.

PID Description Notes
9709 Central Wiring Harness | For main body harness only. Not for sub-harness’ that are replaceable
separately. Ex: door, bumper, or engine harness.
9713 Engine compartment _ | Any repair made to the harness sections in the engine bay NOT connected to
wiring harness the main body harness. Claim notes should specify a location.
9732 Door harness Use for any door. Claim notes should state which door.
9757 Seat harness Use for any location. Claim notes should specify the location.
9779 Roof wiring harness Any repairs made to harness sections in the roof. Claim notes should specify a
location.
9759 Bumper harness Use for front or rear. Claim notes should specify the location.
9781 Transmission wiring Any repair made to the harness that is separate from the main body harness
harness and connects to the transmission.
