Pinpoint Tests
Pinpoint Test M: The Front Controls Interface Module (FCIM) Does Not Respond To The Scan Tool

Number
Normal Operation
The Front Controls Interface Module (FCIM) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN).
Voltage to the FCIM is provided by circuit SBP16 (VT/RD). Ground is provided by circuit GD114 (BK/BU).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
FCIM
PINPOINT TEST M: THE FCIM 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.

M1 CHECK THE FCIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: FCIM C2402 (Without Navigation ACM) or C2403 (With Navigation ACM).
-
Ignition ON.
-
For vehicles without a navigation ACM, measure the voltage between the FCIM C2402-1, circuit SBP16 (VT/RD), harness side and ground.
-
For vehicles with a navigation ACM, measure the voltage between the FCIM C2403-5, circuit SBP16 (VT/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to M2.
No
VERIFY the Smart Junction Box (SJB) fuse 16 (15A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to
identify the possible causes of the short circuit. CLEAR the DTCs. REPEAT the network test with the scan tool.
