Yes
INSTALL a new PRB module. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Pinpoint Test O: The Parking Aid Module (PAM) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 131, Parking Aid for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The Parking Aid Module (PAM) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN). Circuits VDB06
(GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the PAM. Voltage for the PAM is provided by circuit
CBP18 (GY/OG). Circuit GD145 (BK/BU) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
PAM
PINPOINT TEST O: THE PAM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
O1 VERIFY PARKING AID SYSTEM TYPE
-
NOTE: The Explorer uses a radar parking aid system while the Mountaineer and Explorer Sport Trac use an ultrasonic system.
-
Verify the parking aid system.
-
Is the vehicle equipped with a RADAR parking aid system?
Yes
GO to O2.
No
GO to O5 .
-------------------------------------------------
O2 CHECK THE PAM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN (RADAR)
-
Ignition OFF.
-
Disconnect: PAM C4226.
-
Ignition ON.
-
Measure the voltage between the PAM C4226-18, circuit CBP18 (GY/OG), harness side and ground.
