Flex AWD V6-3.5L (2009)
No
VERIFY the auxiliary relay box fuse 1 (10A) is OK. If OK, GO to AB3. If not OK, REFER to the Wiring Diagrams to identify the possible causes of the
circuit short.
-------------------------------------------------
AB3 CHECK FOR VOLTAGE TO THE AUXILIARY RELAY BOX FUSE 1 (10A)
-
Measure the voltage between the auxiliary relay box fuse 1 (10A), input side, circuit CLS10 (GY/BN) and ground.
-
Is the voltage greater than 10 volts?
Yes
REPAIR circuit CAT03 (GY/BN) for an open. TEST the system for normal operation.
No
REPAIR circuit CLS10 (GY/BN) for an open. TEST the system for normal operation.

Refer to Wiring Diagram Set 95, Trailer/Camper Adapter for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By
Number
Normal Operation - Trailer Tow Turn/Stoplamp
The trailer tow LH stop/turn relay coil receives voltage through circuit CLS18 (GY/BN) when the vehicle LH rear stoplamp is illuminated. When the
trailer tow LH stop/turn relay is energized, the voltage is routed to the trailer tow connector through circuit CAT06 (YE).
The trailer tow RH stop/turn relay coil receives voltage through circuit CLS19 (VT/OG) when the vehicle RH rear stoplamp is illuminated. When the
trailer tow RH stop/turn relay is energized, the voltage is routed to the trailer tow connector through circuit CAT09 (GN).
Trailer Tow Parking
The trailer tow parking lamp relay coil receives voltage through circuit CLS30 (VT/WH) when the vehicle parking lamps are illuminated. When the
trailer tow parking lamp relay is energized, the voltage is routed to the trailer tow connector through circuit CAT11 (BN).
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
Trailer tow relay

PINPOINT TEST AC: THE TRAILER LAMPS ARE ON CONTINUOUSLY
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
