Escape 2WD L4-2.5L (2009)
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.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
B1 CHECK THE ABS MODULE VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: ABS Module C155.
-
Ignition ON.
-
Measure voltage between the ABS module, harness side and ground as follows:
Escape And Mariner
-
Are the voltages greater than 10 volts?
Yes
GO to B2.
No
Escape and Mariner, VERIFY the Battery Junction Box (BJB) fuse 18 (20A) and fuse 9 (50A) and the Smart Junction Box (SJB) fuse 34 (5A) are 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. CLEAR the DTCs.
REPEAT the network test with the scan tool.
Hybrid, VERIFY the Battery Junction Box (BJB) fuses 27 (20A), 9 (50A) and 18 (20A) and the Smart Junction Box (SJB) fuse 34 (5A) are 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. CLEAR the DTCs. REPEAT
the network test with the scan tool.
-------------------------------------------------
B2 CHECK THE ABS MODULE GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the ABS module, harness side and ground as follows:
Escape And Mariner
