The infotainment screen may flicker occasionally on some 2019 Volt models. The screen flickering (Fig. 18) may be due to the component packaging inside the instrument panel, which may not provide adequate clearance between the Wi-Fi antenna and the wiring harness, causing electromagnetic interference with the infotainment screen.<\/p>\n

 <\/p>\n

 <\/p>\n

To eliminate the interference, reposition the wiring harness away from the Wi-Fi antenna.<\/p>\n

Refer to Radio Control Assembly Replacement in the appropriate Service Information to access the back of the infotainment screen. (Fig. 19)<\/p>\n

On the rear of the screen, reroute the wires to prevent covering the Wi-Fi antenna on the instrument panel. The components include the Wi-Fi antenna (Fig. 20, #1), Branch Integrated Center Stack (ICS) power cable (Fig. 20, #2), and Branch Low Voltage Differential Signaling (LVDS) cable. (Fig. 20, #3)<\/p>\n

 <\/p>\n

 <\/p>\n

Move the ICS power cable toward the LVDS cable (Fig. 21, #1) and zip-tie the ICS power cable with the LVDS cable near the connection points. (Fig. 21, #2) Use a small zip tie to secure the LVDS cable to a clip loop created behind the key fob sensor. (Fig. 21, #3)<\/p>\n

 <\/p>\n

 <\/p>\n

Ensure the new locations of the wires do not cover the Wi-Fi antenna. Cut excess zip tie length and check that any wires are not rubbing, kinked or pulled too tight. (Fig. 22)<\/p>\n
