Toyota RAV4 (XA40) 2013-2018 Service Manual / Introduction / How to troubleshoot ecu controlled systems / Electronic circuit inspection procedure / Check for short circuit

Toyota RAV4. 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.

Disconnect connectors a and c, and measure the resistance

Standard resistance (fig. 6)

Hint:

Measure the resistance while lightly shaking the wire harness vertically and horizontally.

If the results match the examples above, a short circuit exists between terminal 1 of connector a and terminal 1 of connector c.

Disconnect connector b and measure the resistance.

Standard resistance (fig. 7)

If the results match the examples
above, a short circuit exists between terminal 1 of connector b2 and terminal 1 of connector c.

If the results match the examples above, a short circuit exists between terminal 1 of connector b2 and terminal 1 of connector c.

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 resi ...

Check and replace ecu

Notice: The connector should not be disconnected from the ecu. Perform the inspection from the backside of the connector on the wire harness side. When no measuring condition is specified, ...
