P1585

CIRCUIT DESCRIPTION
Output driver modules (ODMs) are used by the powertrain control module (PCM) in order to turn on many of the current-driven devices that are needed to control various functions. DTC P1585 set indicates that an improper voltage level has been detected on the output circuit which controls the stepper motor cruise control inhibit circuit.

CONDITIONS FOR SETTING THE DTC
^ The ignition is ON.
^ The PCM detects an improper voltage level at the cruise control inhibit signal circuit.
^ The above conditions are present for at least 30 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM does not illuminate the malfunction indicator lamp (MIL).
^ The PCM stores the conditions which were present when the DTC set as Fail Records data only. This information is not stored as Freeze Frame data.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A history DTC clears after 40 malfunction free warm-up cycles.
^ The PCM receives the clear code command from the scan tool.

TEST DESCRIPTION

Steps 1-10:

The number below refers to the step number on the Diagnostic Table.
2. Normally, ignition positive voltage should be present on the control circuit with the PCM disconnected and the ignition turned ON.
