Some customers may experience a no start condition and a loss of low speed LAN communications at times. This concern is often accompanied by several communication codes in several modules.
This concern may be caused by the wiring harness under the passenger seat being pinched between the passenger's seat track and the rearview camera module.
If the wiring harness is found to be pinched in this specified area, the technician should repair the wiring harness as needed and route the harness to the side of the rearview camera module. Use a zip tie to properly secure the harness in place.
After any repair, cycle the front passenger seat forward and back to make sure that the harness has proper clearance.
