P0567
DTC P0567
Circuit Description
The cruise control resume/accel switch is an input to the engine control module (ECM). The ECM monitors the cruise control resume/accel switch signal circuit in order to detect when the driver has requested to accelerate the set vehicle speed or to resume the cruise control system. The ECM module detects a voltage signal on the cruise control resume/accel switch signal circuit when the switch is applied. This DTC sets if the ECM detects that voltage is present on the cruise control resume/accel switch signal circuit for longer than 90 seconds.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC P0567 Cruise Control Resume Switch Circuit
Conditions for Running the DTC
* The ignition is ON.
* The cruise control switch is ON.
Conditions for Setting the DTC
The ECM detects that the resume/accel switch is applied for longer than 90 seconds.
Action Taken When the DTC Sets
* 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.
* The cruise control system is disabled.
Conditions for Clearing the MIL/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.
* Use a scan tool in order to clear the MIL/DTC.
Diagnostic Aids
Ensure that the resume/accel switch is not stuck or sticking in the engaged position.
