PINPOINT TEST 15: THE FRONT CONTROLS INTERFACE MODULE (FCIM) DOES NOT RESPOND TO THE SCAN TOOL - HYBRID

Normal Operation

The front controls interface module (FCIM) communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits (GY/O) (MS-CAN +) and (V/O) (MS-CAN -) provide the network connection to the FCIM. The FCIM shares the MS-CAN network with the instrument cluster, dual automatic temperature control (DATC) module, smart junction box (SJB), audio control module (ACM), front display interface module (FDIM) and satellite digital audio receiver system (SDARS) module. Voltage to the FCIM is provided by circuit (BR/R). Ground is provided by circuit (B/L).

Possible Causes
- Fuse
- Wiring, terminals or connectors
- FCIM

Diagnostic Procedure

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
