DTC P0567 2.2L, 2.4L
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. |

1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | |
Does the Cruise Resume/Accel parameter display On? | Go to Step 3 | Go to Diagnostic Aids | |
Does the Cruise Resume/Accel parameter display On? | Go to Step 4 | Go to Step 5 | |
4 | Test the cruise control resume/accel switch signal circuit for a short to voltage. Refer to Circuit Testing and to Wiring Repairs. Did you find and correct the condition? | Go to Step 9 | Go to Step 6 |
5 | Inspect for poor connections at the harness connector of the cruise control switch. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs. Did you find and correct the condition? | Go to Step 9 | Go to Step 7 |
6 | Inspect for poor connections at the harness connector of the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs. Did you find and correct the condition? | Go to Step 9 | Go to Step 8 |
7 | Replace the cruise control switch. Refer to Steering Wheel Control Switch Assembly Replacement. Did you complete the replacement? | Go to Step 9 | -- |
8 | Replace the ECM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement? | Go to Step 9 | -- |

Does the DTC reset? | Go to Step 2 | System OK |
DTC P0567 3.5L
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.
