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. The Cruise Resume/Accel switch sends an ignition voltage to the PCM when the switch is closed (ON).


CONDITIONS FOR SETTING THE DTC

^ The cruise switch is OFF.

^ The ignition voltage on the Resume switch signal circuit.

or

^ The cruise switch is ON.

^ The resume switch is ON for longer than 25.5 seconds.

ACTION TAKEN WHEN THE DTC SETS

^ The PCM will not illuminate the Malfunction Indicator Lamp (MIL).

^ The PCM records the operating conditions at the time the diagnostic fails. This information stores in the Failure Records.


CONDITIONS FOR CLEARING THE MIL/DTC

^ A History DTC will clear after forty consecutive warm-up cycles during which the diagnostic does not fail (the coolant temperature has risen 5°C (40°F) from the start up coolant temperature and the engine coolant temperature exceeds 71°C (160°F) during that same ignition cycle.

^ Use of a Scan tool will clear the DTC codes.

DIAGNOSTIC AIDS

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

TEST DESCRIPTION

The number(s) below refer to the step number(s) on the Diagnostic Table.

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

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