P0567

DTC P0567

CAUTION: Refer to SIR Caution.

Disable the inflatable restraint steering wheel module when performing this diagnostic table. Refer to SIR Disabling and Enabling Zone 3.

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 voltage signal 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 Circuit

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

DIAGNOSTIC AIDS
Perform the following in order to avoid misdiagnosis:
- Rotate the steering wheel to both steering stops and activate each cruise control switch separately. With a scan tool, observe the associated cruise control switch parameter in the ECM Cruise Control data list. This will help eliminate the possibility of an internally open or shorted inflatable restraint steering wheel module coil.
- 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. Component Tests and General Diagnostics
