Conditions for Running the DTC

The engine is ON.

Conditions for Setting the DTC

* The ECM receives an invalid cruise control switch status.
* This diagnostic runs continuously.

Action Taken When the DTC Sets

* The Cruise Control System is disabled.
* The ECM stores the DTC information into memory when the diagnostic runs and fails.
* The malfunction indicator lamp (MIL) will not illuminate.
* The ECM records the operating conditions at the time the diagnostic fails. The ECM stores this information in the Failure Records.
* All cruise control function switches are set to OFF.

Conditions for Clearing the DTC

* A last test failed, or the current DTC, clears when the diagnostic runs and does not fail.
* A history DTC clears after 40 consecutive warm-up cycles, if failures are not reported by this or any other emission related diagnostic.

Diagnostic Aids

* This DTC may be stored as a history DTC without affecting the operation of the ECM. If stored only as a history DTC and not retrieved as a current DTC, do not replace the ECM.
* If this DTC is retrieved as both a current and history DTC, replace the ECM.
