Pinpoint Tests
Pinpoint Test G: The Transmission Control Module (TCM) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Module Communications Network for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 29 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Transmission Controls for schematic and connector information.
See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The Transmission Control Module (TCM) is present on hybrid vehicles only. The TCM communicates with the scan tool through the High Speed
Controller Area Network (HS-CAN).
NOTE: Only vehicles with a 3.5L gasoline engine or 2.5L hybrid engine are equipped with a TCM. The PCM controls the transmission on 2.5L
gasoline and 3.0L gasoline engine vehicles.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
TCM
PINPOINT TEST G: THE TCM 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.

G1 CHECK THE TCM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: TCM C1458a (2.5L Hybrid) .
-
Disconnect: TCM C1533 (3.5L) .
-
Ignition ON.
-
For 3.5L, measure the voltage between the TCM C1533-1, circuit SBB16 (VT/RD), harness side and ground; and between the TCM C1533-11,
circuit CBP44 (VT), harness side and ground.
-
For 2.5L hybrid, measure the voltage between the TCM, harness side and ground as follows:
