Use a calibrated digital multimeter for making continuity checks or for measuring voltage. For instructions about the use of the 6V-7070 Digital Multimeter, see Special Instruction, SEHS7734. The 7X-1710 Multimeter Probe is used to measure the voltage without disconnecting the connector. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a 3-pin breakout. The adapter cable is used for measurements in the sensor circuits.
Note: Except for harness tests, using continuity testers such as the 8T-0500 Continuity Tester or voltage testers such as the 5P-7277 Voltage Tester is not recommended.
