DTC P0567 Cruise Resume Circuit






Circuit Description

The cruise Resume/Accel switch is an input to the fuel control portion of the PCM. These inputs allow the PCM to control and hold a requested speed. Cruise Resume/Accel switch sends ignition voltage to the PCM when the switch is closed ("ON"). This is a type D DTC.

Conditions for Setting the DTC

^ Cruise switch "OFF".
^ Ignition voltage on Resume switch signal circuit.
or
^ Cruise switch "ON".
^ Resume switch "ON" for longer than 25.5 seconds

Action Taken When the DTC Sets

^ Will not turn on the MIL.
^ The PCM will disallow all cruise inputs.
^ TCC shift schedules may be affected.

Conditions for Clearing the MIL/DTC

^ A History DTC will clear when forty consecutive warm-up cycles that the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from start up coolant temperature and engine coolant temperature exceeds 71°C (16O°F) that same ignition cycle).
^ Use of a Scan Tool.

Diagnostic Aids

Check for a resume / accel switch stuck in the engage position or the signal circuit is shorted to voltage.

Test Description

Number(s) below refer to the number(s) on the diagnostic table.

2. This step determines if the signal circuit is shorted to voltage.

3. This step determines if the PCM or switch is at fault.
