Taurus AWD V6-3.5L (2009)
GO to A5.
No
REPAIR the circuit in question. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
A5 CHECK FOR CORRECT PCM OPERATION
-
Disconnect all the PCM connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the PCM connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new PCM. CONNECT all the modules. 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. CONNECT all the modules.
CLEAR the DTCs. REPEAT the network test with the scan tool.

Normal Operation
The ABS module communicates with the scan tool through the High Speed Controller Area Network (HS-CAN). Circuits VDB04 (WH/BU) (HS-CAN
+) and VDB05 (WH) (HS-CAN -) provide the network connection to the ABS module. The ABS module shares the HS-CAN with the PCM, the
Steering Effort Control Module (SECM), the Restraints Control Module (RCM), the Occupant Classification System Module (OCSM), the 4X4 control
module, the Accessory Protocol Interface Module (APIM) and the Instrument Cluster (IC). Voltage for the ABS module is provided by circuit CBB38
(GY/BU), and ground is provided by circuit GD120 (BK/GN).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
ABS module
PINPOINT TEST B: THE ABS MODULE 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.
