Toyota Sienna Service Manual: Check for short circuit

If the wire harness is ground shorted, locate the section by conducting a resistance check with the body ground (below).

(a) 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

(b) Check the resistance with the body ground.

(1) 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 your results match the examples above, an open circuit exists between terminal 1 of connector A and terminal 1 of connector C.

(2) Disconnect connector B and measure the resistance.

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.

Check for open circuit
(a) For an open circuit in the wire harness in Fig. 1, the resistance or voltage, as described below. (b) Check the resistance.  Check the resistance Standard resistance (Fig. 2) ...
