Toyota Sienna Service Manual: 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)
HINT:
Measure the resistance while lightly shaking the wire harness vertically and horizontally. If the 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 between the terminals of the connectors.
Standard resistance (Fig. 3)
If the results match the examples above, an open circuit exists between terminal 1 of connector B2 and terminal 1 of connector C.
(c) Check the voltage.
Check the voltage
(1) In a circuit in which voltage is applied to the ECU connector terminal, an open circuit can be checked by conducting a voltage check.
With each connector still connected, measure the voltage between the body ground and these terminals (in this order): 1) terminal 1 of connector A, 2) terminal 1 of connector B, and 3) terminal 1 of connector C.
Standard voltage (Fig. 4)
If the results match the examples above, an open circuit exists in the wire harness between terminal 1 of connector B and terminal 1 of connector C.
Basic inspection
(a) WHEN MEASURING RESISTANCE OF
ELECTRONIC PARTS
(1) Unless otherwise stated, all resistance
measurements should be made at an ambient
temperature of 20°C (68°F). Resistance
measurements may b ...
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.

DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures
that the ECM is
functioning properly. If outputs from the CPUs are different and deviate from
the standards, the ECM will
illuminate the MIL and set a DTC immediately ...
