Fusion FWD V6-3.5L (2010)
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
ACM
PINPOINT TEST M: THE ACM 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.
-------------------------------------------------
M1 CHECK THE ACM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: ACM C240a .
-
Ignition ON.
-
Measure the voltage between the ACM C240a-1, circuit SBP39 (WH/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to M2.
No
VERIFY the Smart Junction Box (SJB) fuse 39 (20A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to
identify the possible causes of the circuit short See: Diagrams/Electrical Diagrams/Diagrams By Number. CLEAR the DTCs. REPEAT the network test
with the scan tool.
-------------------------------------------------
M2 CHECK THE ACM GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable .
-
Measure the resistance between the ACM C240a-13, circuit GD114 (BK/BU), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
