DTC P0567 2.2L, 2.4L


Object Number: 1402839  Size: MF

Circuit Description

The cruise control resume/accel switch is an input to the engine control module (ECM). The ECM uses 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 detects a high signal voltage on the cruise control resume/accel switch signal circuit when the switch is applied.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0567 Cruise Control Resume Switch

Conditions for Running the DTC

    • The ignition is ON.
    • The cruise control On/Off switch is ON.

Conditions for Setting the DTC

The ECM detects a high signal voltage on the cruise control resume/accel switch signal circuit for longer than 60 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.
    • For an intermittent condition, refer to Testing for Intermittent Conditions and Poor Connections.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. This step determines if condition is present.

  2. This step determines if the switch is at fault.

DTC P0567 3.5L


Object Number: 1402847  Size: MF

Circuit Description

The cruise control resume/accel switch is an input to the powertrain control module (PCM). The PCM uses 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 PCM detects a high signal voltage on the cruise control resume/accel switch signal circuit when the switch is applied.

DTC Descriptor

This diagnostic procedure supports the following DTC:

    • The cruise control On/Off switch is ON.

Conditions for Setting the DTC

The PCM detects a high signal voltage on the cruise control resume/accel switch signal circuit for longer than 60 seconds.

Action Taken When the DTC Sets

    • The PCM stores the DTC information into memory when the diagnostic runs and fails.
    • The malfunction indicator lamp (MIL) will not illuminate.
    • The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this information in the Failure Records.
    • The cruise control system is disabled.
    • The Service Vehicle Soon (SVS) light may be illuminated.

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.
