4 Runner 2WD L4-2.7L (2TR-FE) (2010)
(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.
