1 arness onnector Terminal ayout UBS007V Terminals and Reference Value PRPRTON 1. is located behind the instrument lower cover. or this inspection: Remove instrument lower cover. S533P UBS007V Remove harness protector. 3. Perform all voltage measurements with the connector connected. xtend tester probe as shown to perform tests easily. Open harness securing clip to make testing easier. Use extreme care not to touch 2 pins at 1 time. ata is for comparison and may not be exact B NSPTON TB Specification data are reference values and are measured between each terminal and ground. UTON: o not use ground terminals when measuring input/output voltage. oing so may result in damage to the 's transistor. Use a ground other than the terminals, such as the ground. -661
