-
Measure the resistance between the PCM C175b-23, circuit 1828 (PK/LG), harness side and the DLC C251-14, circuit 1828 (PK/LG), harness
side.
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to K19.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CONNECT the PCM. CLEAR the DTCs. REPEAT the network test with the
scan tool.
