Scan Tool Testing and Procedures









CRUISE CONTROL SYSTEM: DATA LIST / ACTIVE TEST

CRUISE CONTROL SYSTEM: DATA LIST / ACTIVE TEST

1. READ DATA LIST
HINT: Using the Techstream Data List allows switch, sensor, actuator, and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to save time.

(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Read the Data List according to the display on the tester.

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 CRUISE main indicator light does not illuminate -> CRUISE main indicator light, wire harness, or ECM failure
