Pinpoint Test - DTC: R — 2016 workshop reference 1925

Positive Lead	Measurement / Action	Negative Lead
C2280E-49		Ground

Is the resistance greater than 10,000 ohms?

Yes	GO to A4
No	REPAIR the circuit. Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A9

A4 CONFIRM THE BCM (BODY CONTROL MODULE) OR RCM (RESTRAINTS CONTROL MODULE) FAULT

NOTE: Make sure all SRS electrical connectors and the BCM electrical connector are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.

Prior to reconnecting any previously disconnected SRS component:

Inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals. Inspect wire harness for any damage, pinched, cut or pierced wires. Repair any concerns found. Refer to Wiring Diagrams Cell 5 for schematic and connector information.

Connect BCM C2280E. Connect RCM C310A and C310B. Repower the SRS. Do not prove out the SRS at this time. REFER to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System, General Procedures). Ignition ON. Using a diagnostic scan tool, perform the RCM self-test to retrieve Diagnostic Trouble Codes (DTCs).

Was DTC B11D8:14 retrieved on-demand during self-test?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Click here to access Guided Routine (BCM). CLEAR the RCM Diagnostic Trouble Codes (DTCs) and REPEAT the RCM self-test. If DTC B11D8:14 returns, INSTALL a new RCM. REFER to: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation). GO to A9 If DTC B11D8:14 does not return, GO to A9
No	In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. SRS components should only be installed when directed to do so in the pinpoint test. GO to A8

A5 CHECK THE EVENT NOTIFICATION SIGNAL CIRCUIT DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE

NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the fault reported changes, this indicates the RCM is functioning correctly and is not the source of the fault.

Disconnect BCM C2280E. Using a diagnostic scan tool, perform the RCM self-test to retrieve Diagnostic Trouble Codes (DTCs).
