P0567

CIRCUIT DESCRIPTION
The cruise control resume/accel switch is an input to the powertrain control module (PCM). This allows the PCM to control and hold a requested speed. The cruise control resume/accel switch sends an ignition positive voltage signal to the PCM when the switch is applied. This DTC sets if the PCM senses a voltage on the resume/ accelerate switch signal circuit when voltage is not expected

CONDITIONS FOR RUNNING THE DTC
The cruise control 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 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

IMPORTANT: For any test that requires probing the PCM or a component harness connector, use the J 35616-A Connector Test Adapter Kit. Using this kit prevents damage to the harness/component terminals. Refer to Using Connector Test Adapters in Diagnostic Aids.

^ Inspect for a resume/accel switch stuck in the engage position or the signal circuit is shorted to voltage.
^ For an intermittent, refer to Testing for Intermittent and Poor Connections in Diagnostic Aids.

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.
