Toyota RAV4 (XA40) 2013-2018 Service Manual: Check for open circuit
- For an open circuit in the wire harness in fig. 1, Check the resistance or voltage, as described below.
- Check the resistance.
- 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.
- 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.
- Check the voltage.
- 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)
If the results match the examples
above, an
open circuit exists in the wire harness between
terminal 1 of connector b and terminal 1 of
connector c.
Basic inspection
When measuring resistance of
electronic parts
Unless otherwise stated, all resistance
measurements should be made at an ambient
temperature of 20°c (68°f). Resistance

Check for short circuit
If the wire harness is ground shorted (fig. 5), Locate
the section by conducting a resistance check with
the body ground (below).
Check the resistance with the body ground.
