P0243

CIRCUIT DESCRIPTION
Output Driver Modules (ODM) are used by the Powertrain Control Module (PCM) to turn ON many of the current-driven devices that are needed to control various engine and Transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device which the PCM is commanding ON. Unlike the Quad Driver Modules (QDM) used in prior model years, ODMs have the capability of diagnosing each output circuit individually. If an improper voltage level has been detected on the supercharger boost control solenoid control circuit, DTC P0243 will set.

CONDITIONS FOR SETTING THE DTC
^ The ignition is ON.
^ An improper voltage level has been detected on the boost control solenoid control circuit.
^ The above conditions are present for at least 30 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ The control module stores the DTC information into memory when the diagnostic runs and fails.
^ The Malfunction Indicator Lamp (MIL) will not illuminate.
^ The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records.
^ The driver information center, if equipped, may display a message.

CONDITIONS FOR CLEARING THE DTC
^ A current DTC "Last Test Failed" clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
^ Use a scan tool in order to clear the DTC.

DIAGNOSTIC AIDS

TEST DESCRIPTION

Steps 1-8:

Steps 9-16:

The numbers below refer to the step numbers on the diagnostic table.
3. This test can detect a partially shorted coil which would cause excessive current flow. Leaving the circuit energized for 2 minutes allows the coil to warm up. When warm, the coil may open, and the amps drop to 0, or the coil may short, and the amps goes above 800 mA.
4. This step tests for a short to voltage on the control circuit.
