Toyota RAV4 (XA40) 2013-2018 Service Manual: Check for open circuit

Toyota RAV4. Check for open circuit


  1. For an open circuit in the wire harness in fig. 1, Check the resistance or voltage, as described below.
  2. Check the resistance.

Toyota RAV4. Check for open circuit


  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.

  1. 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.

  1. Check the voltage.

Toyota RAV4. 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)

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 measurements m ...

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. Disconne ...
