Check short circuit

1. 1
   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).

   

2. 2
   Check the resistance with the body ground.
3. 3
   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.

2. 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.
