Toyota Corolla (E120): Check short circuit
- If the wire harness is ground shorted as shown in fig. 5, Locate the section by conducting a resistance check with the body ground in step (b).
- Check the resistance with the body ground.
- Disconnect connectors a and c and measure the
resistance between terminals 1 and 2 of connector
a and the body ground.
Resistance: 10 kΩ or higher
Hint
: measure the resistance while lightly shaking the wire harness vertically and horizontally. In the case of fig. 6: Between terminal 1 of connector a and body ground " below 1 Ω
between terminal 2 of connector a and body ground " 10 kΩ
or higher therefore, the cause is a short circuit between terminal 1 of connector a and terminal 1 of connector c.
- Disconnect connector b and measure the resistance
between terminal 1 of connector a and the
body ground, and terminal 1 of connector b2 and
the body ground.
In the case of fig. 7: Between terminal 1 of connector a and body ground " 10 kw or higher between terminal 1 of connector b2 and body ground " below 1 w therefore, the cause is a short circuit between terminal 1 of connector b2 and terminal 1 of connector c.
