Pinpoint Test O : B103B, B1111

NOTE: When taking measurements at 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 DTCs and system failure. Touching the tip of these connector pins is recommended instead.
