PINPOINT TEST AH : DTCs B103B AND B1111

NOTE: When taking measurements at Dual Climate Controlled Seat Module(DCSM) harness connectors, do not insert the electrical probes into the female connector pins. Inserting the probes into connector pins can cause intermittent or open electrical connections after reassembly resulting in Diagnostic Trouble Codes (DTCs) and system failure. Touching the tip of these connector pins is recommended instead.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module(RCM) fuse is removed and the ignition switch is ON.
NOTE: The Supplemental Restraint System(SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
