The trailer tow parking lamp relay coil receives voltage when the vehicle parking lamps are illuminated. The Smart Junction Box (SJB) fuse 38 (20A)
supplies voltage to the trailer tow parking lamp relay switch side. When the trailer tow parking lamp relay is energized, voltage is routed to the trailer
tow connector.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Trailer tow connector
