DESCRIPTION:
* This TJ supersedes the previous TJ 31295 dated 7/10/2017
* New software released
CCD = Center Console Display
DIM = Driver Information Module
IHU = Infotainment Head Unit
________________________________
The customer may report that the infotainment system in the vehicle re-starts or reboots intermittently
while driving.
When this happens the CCD and the center area of the DIM will go blank for a few moments and then
start back up as if the vehicle has just been started up.
The customer may also notice that the infotainment system is not responding as normal (ex.- long
response time) just before this occurs.
When the system reboots, some customer settings may change back to a previous setting (ex.- navi
destination, climate settings, radio station, etc.)
Follow the instructions under Service to repair this condition.
*New IHU software is available to improve the IHU stability.
SERVICE:
*System reboots have many underlying root causes. Volvo Cars is working to improve and eliminate
these root causes. In most cases, replacing IHU hardware will not solve or prevent system reboots. The
IHU should only be replaced for this symptom if it is recommended by the Technical HelpDesk and/or a
Field Technical Specialist.
* Further improved IHU software is available for download as of October 2nd, 2017 and can be
installed by performing a Total Upgrade.
If a customer complains of system reboots, ensure the following:
- The IHU software should be upgraded with the latest software by performing Total Upgrade as per
TJ 31543. Also check if TJ 32714 applies.
- Make sure any on-board apps are of the latest version by checking for updates in the Download
Center in Sensus.

- If possible, ask the customer if the reset(s) occurs while using a particular app or Media source.
Follow instructions under Vehicle Report and note which app or Media source the customer was
using when the symptom occurred.
- The HelpDesk may request to have log files extracted from the IHU and will provide instructions (see
guidelines under Vehicle Report).
VEHICLE REPORT:
Yes, please submit a Vehicle Report if the service solution(s) described in this TJ has no effect. Use
concern area “Vehicle Report” and sub concern area “Support needed”, use function group 3900.
