Ranger 2WD V6-4.0L (2010)
REPAIR the DLC as necessary. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
A2 VERIFY WHETHER OTHER HS-CAN MODULES PASS THE NETWORK TEST
-
Ignition ON.
-
Enter the following diagnostic mode on the scan tool: Network Test.
-
In the LH pane of the Integrated Diagnostic System (IDS) network test display screen, verify whether any HS-CAN modules passed the network
test.
-
Is the text "pass" or a DTC listed next to any of the following modules (if equipped): 4X4 control module, ABS module, Instrument
Cluster (IC), Occupant Classification System Module (OCSM), Restraints Control Module (RCM), Smart Junction Box (SJB) or PCM?
Yes
If "pass" or a DTC was listed next to the PCM, a network fault is not currently present. GO to Pinpoint Test H to diagnose an intermittent HS-CAN fault
condition. See: Pinpoint Test H: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not
Respond
If "pass" or a DTC was listed next to one or more modules other than the PCM, GO to A3.
No
No modules are currently communicating on the HS-CAN. GO to Pinpoint Test I to diagnose no HS-CAN communication. See: Pinpoint Test I: No
High Speed Controller Area Network (HS-CAN) Communication, All Modules Are Not Responding
-------------------------------------------------
A3 CHECK THE PCM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: PCM C175b.
-
Ignition ON.
-
Measure the voltage between the PCM, harness side and ground as follows:
-
Are the voltages greater than 10 volts?
Yes
GO to A4.
No
VERIFY the Battery Junction Box (BJB) fuses 21 (10A) and 39 (15A) are OK.
If OK, REPAIR the circuit in question.
