TT150 Status LEDs are Off
Problem: TT150 Status LEDs are Off
Both LEDs should be lit and solid when the trailer’s 7-way is receiving power. If both LEDs are
off, this indicates one of two possible conditions:
•
The LEDs have been disabled via the Trailer Tracks Portal or the TT150 FST. Change
the setting if needed.
•
The TT150 terminal is not currently detecting power via the trailer’s 7-way connector
and the TT150 terminal is asleep.
1.
Check that power is being supplied by the tractor to the trailer’s 7-way connector by
measuring voltage on the pig tail from the truck.
