PINPOINT TEST D : An Individual Or Group Of Flashing LEDs Do Not Synchronize Correctly Or Display An Incorrect Pattern: Notes

Diagnostic Overview 

An Individual Or Group Of Flashing LEDs Do Not Synchronize Correctly Or Display An Incorrect Pattern 

Normal Operation and Fault Conditions 

The front park or turn or warn, tail lamp and front corner flashing LEDs typically have 2 versions of each pattern. If the flashing LEDs are set to the same version of the pattern, they will flash on and off at exactly the same time. If the flashing LEDs are set to different versions of the same pattern, they will flash on and off at exactly opposite times. If the flashing LEDs are out of synchronization, the on and off flash of the flashing LEDs may overlap and not flash the same or opposite.

The grille, high mount and liftgate flashing LEDs typically have 4 versions of each pattern. These flashing LEDs are made up of 6 individual LEDs. The addition of 2 more versions of patterns control each side (3 LEDs) of an individual flashing LED. This allows the synchronization of each side of a singe flashing LED as well as each side of the vehicle.
