DTC P0567

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 voltage signal on the cruise control resume/accel switch signal circuit when the switch is applied. This DTC sets if the PCM senses voltage on the cruise control resume accel switch signal circuit for longer than 90 seconds.

CONDITIONS FOR RUNNING THE DTC
The cruise control On/Off switch is ON.

CONDITIONS FOR SETTING THE DTC
The PCM detects the resume/accel switch is ON for longer than 90 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.

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 and Poor Connections in Diagnostic Aids.

TEST DESCRIPTION

Steps 1-9:

The numbers below refer to the step numbers on the diagnostic table.
2. This step determines if condition is present.
3. This step determines if the switch is at fault.
