Toyota Sienna Service Manual: Data list / active test
1. READ DATA LIST
HINT: 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 before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
- Connect the intelligent tester to the DLC3.
- Turn the ignition switch to the ON position.
- Read the DATA LIST according to the display on the tester.
LASER CRUISE:
HINT: "3" is OK, but "1" is NG → ECM failure "1" is OK, but "2" is NG → DTC output or ECM failure "3" is OK, but cruise indicator does not turn on → Indicator, wire harness, or ECM failure
2. ACTIVE TEST
HINT: Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
- Connect the intelligent tester to the DLC3.
- Turn the ignition switch to the ON position.
- According to the display on the tester, perform the "ACTIVE TEST".
HINT: The ignition switch must be turned to the ON position to proceed with the Active Test using an intelligent tester.

VC Output Circuit
DESCRIPTION
The ECM constantly uses 5 V from the battery voltages supplied to the +B
(BATT) terminal to operate the
microprocessor. The ECM also provides this power to the sensors through the VC
output circuit.
When the VC circuit is short-circuited, the microprocessor in the ECM and
sens ...

1. INSTALL NO. 1 COOLER THERMISTOR
(a) Install the No. 1 cooler thermistor as shown in the
illustration.
NOTICE:
Be sure to insert the thermistor only once
because reinserting it will not allow it to be
firmly secured.
When reusing the evaporator, insert the
thermistor one row ne ...
