Toyota RAV4 (XA40) 2013-2018 Service Manual: 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.
