CRUISE CONTROL: CRUISE CONTROL SYSTEM: DATA LIST / ACTIVE TEST

DATA LIST / ACTIVE TEST

1. READ 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.

(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to the ON position.
(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.

ECM (Cruise Control):





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 the cruise indicator does not come on -> CRUISE main indicator, wire harness or ECM failure
