DTC Descriptor

DTC P0575

- Cruise Control Switch Signal Circuit

Circuit/System Description

When a cruise control function switch is activated, the body control module (BCM) detects a predetermined voltage signal. The BCM sends a serial

data message to the engine control module (ECM) indicating the function that has been requested.

Conditions for Running the DTC

* The ignition is ON.

* The cruise switch is ON.

Conditions for Setting the DTC

* The ECM receives an invalid cruise control switch status serial data message from the BCM.

* This diagnostic runs continuously.

Actions Taken When the DTC Sets

* The cruise control system becomes disabled.

* The malfunction indicator lamp (MIL) will not illuminate.
