Condition
Customer states:

A warning or malfunction is present.
Workshop findings:
 A wiring 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 retain the photos for at least 1 month after the claim is approved in case
they are needed during warranty review.
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.
Note:
In the technician 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 the 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.

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 TAC case: Please retain photos for at least 1 month after claim approval in case they are requested during
claim review.
TAC case present: If a case is made before or after a wiring issue is identified, please update the TAC case
with all information described above.

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.
