Pinpoint Test AE : DTC B1113/B111B

NOTE: When taking measurements at Front Seat Climate Control Module (SCME) 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 airbag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
