Escape 2WD L4-2.5L (2009)
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to A5.
No
REPAIR the circuit in question. CONNECT the negative battery cable. 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 modules. CONNECT the negative battery cable. 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 modules. CLEAR
the DTCs. REPEAT the network test with the scan tool.

Normal Operation - Escape and Mariner
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. Voltage for the ABS module is provided by circuits CBP34
(VT/BN), SBB09 (RD) and SBB18 (YE/RD). Ground is provided by circuit GD120 (BK/GN).
