REVISION SUMMARY
Under PARTS INFORMATION and FAKRA Splice Repair Service Cable Assembly, information was added.
BACKGROUND
A coaxial cable terminal was not manufactured to proper specifications. An improperly manufactured terminal may lead to
poor communication in the media-oriented system transport (MOST) bus network which can potentially affect the audio
sound quality.
Acura is extending the warranty coverage on the FAKRA service cables to 8 years or 100,000 miles from the original date
of purchase, whichever comes first.

CLIENT NOTIFICATION
Owners of affected vehicles must be sent a notification of this campaign; do an iN VIN status inquiry to verify eligibility.

CORRECTIVE ACTION
Install the FAKRA splice repair service cables and splice boxes.
PARTS INFORMATION
IMPORTANT: The splice boxes (P/N 39817-THR-305) used in this Safety Recall have lock tabs that may be susceptible to
breakage during installation if too cold.
•

DO NOT store splice boxes in cold temperatures, around 14°F (-10°C) or colder.

FAKRA Splice Repair Service Cable Assembly
IMPORTANT: The splice boxes (P/N 39817-THR-305) used in this Safety Recall have lock tabs that may be susceptible to
breakage during installation if too cold.
•

DO NOT store splice boxes in cold temperatures, around 14°F (-10°C) or colder.

•

DO NOT attempt to repair or use a damaged splice box. If any of the splice box lock tabs break during installation,
replace with a new splice box.

1. Install the appropriate FAKRA splice repair service cables and splice boxes as shown in the steps that follow:
NOTE:
•
•
•
•

The splice box arrow must always point in the direction of the red flag label or red sleeve on the FAKRA
splice repair service cable.
The splice box is a ONE-TIME use part. Never reuse the splice box after it has been installed.
If any of the lock tabs break during installation, the splice box halve(s) must be replaced.
If the splice box is installed incorrectly, the repair will fail; MOST ring failure conditions will still occur.

2. Use a small screwdriver to remover the secondary lock, then release the tab.

3. Pull to remove the housing from the cable and then discard the housing and secondary lock tab from the FAKRA splice
repair service cable.

When reinstalling components, make sure the harness is routed correctly. A misrouted harness can put pressure on
the wires and connectors causing connection issues.
Do not pull on the units or MOST cables while the FAKRA connectors are connected to help prevent communication
issues.
The front and rear climate control unit’s self-diagnostic function must be done with the i-HDS, or the climate control
will not function correctly.

2. Start the vehicle and verify that the gauge control module and infotainment control module are operating normally. Then,
push the power button to OFF mode. Open and close the driver’s door, then restart the vehicle. Reverify the gauge
control module and the infotainment control module are operating normally. If all systems operate normally, the repair is
complete.
3. If components do not operate as intended, reinspect FAKRA splice repair service cables, splice box connections, and
routing. Make sure the splice box arrow is pointing to the red flag label or red sleeve on the FAKRA splice box service
cable.
NOTE: If all FAKRA splice repair service cables, splice box connections, and routing are correct, follow normal
troubleshooting procedures per a System Information search on iN.
