Some 2016-2018 Edge vehicles may exhibit an intermittently inoperative turn signal tick-tock sound from the instrument panel cluster (IPC) when the turn signal is active. This may be due to the software in the IPC. To correct the condition, reprogram the IPC using the latest software level of the appropriate Ford diagnostic scan tool. For claiming use causal part 10849 Section 10 of the Service Labor Time Standards (SLTS) Manual.
