Flex AWD V6-3.5L (2009)
-
Is the voltage greater than 10 volts?
Yes
GO to Z7.
No
VERIFY the auxiliary relay box fuse 2 (15A) is OK. If OK, REPAIR circuit CB101 (BU) for an open. TEST the system for normal operation. If not OK,
REFER to the Wiring Diagrams to identify the possible causes of the circuit short.

Z7 CHECK THE TRAILER TOW STOP/TURN RELAY COIL GROUND CIRCUIT FOR AN OPEN
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the trailer tow LH stop/turn relay pin 2, circuit GD120 (BK/GN), relay box face side and ground; or between the
trailer tow RH stop/turn relay pin 2, circuit GD120 (BK/GN), relay box face side and ground.
-
Is the resistance less than 5 ohms?
Yes
REPAIR circuit CAT06 (YE) (LH trailer stop/turn) or circuit CAT09 (GN) (RH trailer stop/turn) for an open. TEST the system for normal operation.
No
REPAIR circuit GD120 (BK/GN) for an open. TEST the system for normal operation.

Normal Operation
The trailer tow parking lamp relay coil receives voltage through circuit CLS30 (VT/WH) when the vehicle parking lamps are illuminated. The trailer tow
parking lamp relay coil is grounded through circuit GD120 (BK/GN). The auxiliary relay box fuse 12 (20A) supplies voltage to the trailer tow parking
lamp relay switch side. When the trailer tow parking lamp relay is energized, the voltage is routed from circuit CB102 (GN) through the trailer tow
parking lamp relay and circuit CAT11 (BN) to the trailer tow connector.
This pinpoint test is intended to diagnose the following:
