Scan Tool Testing and Procedures
CRUISE CONTROL: CRUISE CONTROL SYSTEM: DATA LIST / ACTIVE TEST
1. DATA LIST
HINT
Using the Techstream 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.
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Cruise Control / Data List.
(e) Read the Data List according to the display on the Techstream.
(f) *1: for 2ZR-FE
*2: for 2AZ-FE
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 -> CRUISE main indicator light, wire harness, or ECM failure
2. ACTIVE TEST
HINT
Using the Techstream 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 trouble shooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Combination Meter / Active Test.
(e) Perform Active Test according to the display on the Techstream.
HINT
The ignition switch must be turned to ON to proceed with the Active Test using the Techstream.
