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
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.

Control module communication bus off
Description
The power steering ecu receives signals from the ecm and the skid control ecu
via the can
communication system.
Hint:
When 2 or more dtcs starting with [u] are output simultaneously, inspect
the connectors and wire
harness of each ecu.
If dtc u0105/41 is output, fi ...
