PINPOINT TEST J: THE ACM 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.
-------------------------------------------------
J1 CHECK THE ACM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: ACM C290a.
-
Ignition ON.
-
Measure the voltage between the ACM C290a-1, circuit SBP03 (BU/RD), harness side and ground; and between the ACM C290a-2, circuit
CBP12 (GN/WH), harness side and ground.
-
Are the voltages greater than 10 volts?
Yes
GO to J2.
No
VERIFY the Smart Junction Box (SJB) fuse 3 (20A) or fuse 12 (5A) is 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. See: Diagrams/Electrical
Diagrams/Diagrams By Number
-------------------------------------------------
J2 CHECK THE ACM GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the ACM C290a-13, circuit GD114 (BK/BU), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to J3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
J3 CHECK THE MS-CAN CIRCUITS BETWEEN THE ACM AND THE DLC FOR AN OPEN
-
Disconnect: ACM C290b.
-
Measure the resistance between the ACM C290b-15, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06 (GY/OG),
