Toyota Sienna Service Manual: Check for short circuit
(a) If the wire harness is ground shorted (Fig. 5), locate the section by conducting a resistance check with the body ground (below).
(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.
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.

Data list / active test
1. DATA LIST
Using the intelligent tester to read the Data List allows
the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be discovered
befor ...
