Communications Network — 2016 workshop reference 5960

Disconnect modules one at a time until the resistance to ground is greater than 1,000 ohms.

APIM (if equipped) C2383 or C2342 (touchscreen display) Body Control Module B (BCMB) C4368A DDM C501A DSM C341D FCIM C2357A GPSM C2398 Moveable Roof Control Module A (MRCMA) C4830 (if equipped) Moveable Roof Control Module B (MRCMB) C4831 (if equipped) PDM C652A RTM C4458 SCME C3265C (if equipped) SODL C4369 (if equipped) SODR C4370 (if equipped)

Did the resistance change to greater than 1,000 ohms with one of the modules disconnected?

Yes	For the APIM, GO to AG28 For the Body Control Module (BCMB), GO to AG29 For the DDM, GO to AG32 For the DSM, GO to AG34 For the FCIM, GO to AG30 For the GPSM, GO to AG33 For the Moveable Roof Control Module A (MRCMA), GO to AG35 For the Moveable Roof Control Module B (MRCMB), GO to AG36 For the PDM, GO to AG37 For the RTM, GO to AG38 For the SCME, GO to AG39 For the SODL, GO to AG40 For the SODR, GO to AG41
No	REPAIR the circuit in question.

AG12 CHECK FOR RESTORED COMMUNICATION WITH THE GWM (GATEWAY MODULE A) DISABLED

NOTE: When re-running the network test, close the Network Test application first or the screen display reverts back to the prior run Network Test results.

Disconnect BCM fuse 13 (7.5A). Using a diagnostic scan tool, perform the network test.

Do all other MS-CAN modules pass the network test?

Yes	INSTALL the removed fuse. GO to Pinpoint Test AC
No	INSTALL the removed fuse. GO to AG13

AG13 CHECK FOR RESTORED NETWORK COMMUNICATION WITH THE FCIM (FRONT CONTROLS INTERFACE MODULE) DISABLED

Disconnect: BCM fuse 12 (7.5A) to disable the FCIM. Using a diagnostic scan tool, perform the network test.

Do all other MS-CAN modules pass the network test?

Yes	INSTALL the removed fuse. GO to Pinpoint Test K
No	INSTALL the removed fuse. GO to AG14
