LS 460 V8-4.6L (1UR-FSE) (2007)
2. Disconnect connector B and measure the resistance between the connectors.
If the results match the examples, an open circuit exists between terminal 1 of connector B2 and terminal 1 of connector C.
c. Check the voltage.
1. In a circuit in which voltage is applied to the ECU connector terminal, an open circuit can be checked by conducting a voltage check. With
each connector still connected, measure the voltage between the body ground and these terminals (in this order): 1) terminal 1 of connector A;
2) terminal 1 of connector B; and 3) terminal 1 of connector C.
If the results match the examples, an open circuit exists in the wire harness between terminal 1 of connector B and terminal 1 of connector C.
