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.

Technical Service Bulletin
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.

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).
