-
For Expedition, measure the resistance between the PAM C4226-4, circuit VDB06 (GY/OG), harness side and the Data Link Connector (DLC)
C251-3, circuit VDB06 (GY/OG), harness side.
-
For Expedition, measure the resistance between the PAM C4226-5, circuit VDB07 (VT/OG), harness side and the DLC C251-11, circuit VDB07
(VT/OG), harness side.
-
For Navigator, measure the resistance between the PAM C4014a-3, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06
(GY/OG), harness side.
-
For Navigator, measure the resistance between the PAM C4014a-11, circuit VDB07 (VT/OG), harness side and the DLC C251-11, circuit VDB07
(VT/OG), harness side.
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to S4.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
S4 CHECK FOR CORRECT PAM OPERATION
