(a) For an open circuit in the wire harness in Fig. 1, check the resistance or voltage, as described below.
(b) Check the resistance.
(1) Disconnect connectors A and C and measure the resistance between them.
Standard resistance (Fig. 2):
HINT: Measure the resistance while lightly shaking the wire harness vertically and horizontally. If the results match the examples above, an
open circuit exists between terminal 1 of connector A and terminal 1 of connector C.
(2) Disconnect connector B and measure the resistance between the connectors.
Standard resistance (Fig. 3):
If the results match the examples above, 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.
Standard voltage (Fig. 4):
