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 either the red flag label or red sleeve on the
FAKRA splice repair service cable.
• If the splice box is installed incorrectly, the repair will fail; MOST ring failure conditions will still occur.
• Some vehicles may not use the 90° FAKRA splice repair service cables.

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

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

4. Connect the appropriate color FAKRA splice repair service cable to the vehicle harness.
NOTE:
• Make sure the FAKRA service cable is inserted straight into the vehicle harness terminal to avoid damage at
the cable connection point.
• Always disassemble the connectors one at a time to avoid swapping the green and red wires.

5. Attach the splice box halves to the cable connection.

6. When mating the two splice box halves, make sure that all 6 lock tabs are fully engaged. You may hear a click when
installing the two halves.
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.

7. Make sure the arrow on the splice box faces towards the red flag label or red sleeve.
NOTE: Do not spin the splice box or the cables as this can cause damage to the connection point.

8. Once the FAKRA splice repair service cables and splice boxes have been attached to the cable connection, tape
the splice boxes and FAKRA service cables to the appropriate component harness.
NOTE: Reference below for a correct example of the cable connection routing.

REPAIR VERIFICATION PROCEDURE
1. Install all of the removed parts in the reverse order of removal.
NOTE:
• 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.

2. Start the vehicle and verify the gauge control module and the infotainment control unit operates normally, then push
the power button OFF. Open and close the driver’s door and restart the vehicle to reverify the gauge control module
and the infotainment control unit operates normally. If all systems operate normally, 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 System Information Search on iN.
