Pinpoint Test - DTC: AJ — 2016 workshop reference 2043

Positive Lead	Measurement / Action	Negative Lead
C3043-6		Ground

Is the resistance less than 1 ohm?

Yes	GO to A6
No	For the RCM, VERIFY there is no corrosion between the RCM and the mounting surface. VERIFY the fasteners are clean and tightened to specification with no corrosion. REPAIR as necessary. Refer to Wiring Diagrams Cell 5 for schematic and connector information. For the OCSM, REPAIR the circuit. Refer to Wiring Diagrams Cell 5 for schematic and connector information. CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Yes

A6 CHECK FOR MODULE OPERATION

Ignition OFF. If not previously directed to do so, depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect the module with the concern:

For the RCM, disconnect C310A and C310B (if not previously disconnected). For the OCSM, disconnect OCSM C3043 (if not previously disconnected).

Check for the following:

corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary

Connect the module with the concern:

For the RCM, connect C310A and C310B. Make sure the connector seats correctly and engages the Connector Position Assurance (CPA) lever/lock. For the OCSM, connect C3043. Make sure the connector seats correctly.

Repower the SRS. REFER to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System, General Procedures).

Is the concern still present?

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 and DTC U3003:16 or U3003:17 was present in the RCM, INSTALL a new RCM. REFER to REFER to: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation). If no Technical Service Bulletins (TSBs) address this concern and DTC U3003:16 or U3003:17 was present in the OCSM, INSTALL a new OCSM. REFER to: Occupant Classification System (OCS) Sensor (501-20B Supplemental Restraint System, Removal and Installation).
No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
