1847 (WH/OG), harness side.
-
Measure the resistance between the ACM C290a-16, circuit 1848 (PK/OG), harness side and the DLC C251-11, circuit 1848 (PK/OG), harness
side.
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to E4.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
E4 CHECK FOR CORRECT ACM OPERATION
