CIRCUIT DESCRIPTION
Output Driver Modules (ODMs) are used by the 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. ODMs have the capability of diagnosing each output circuit individually. DTC P0650 set indicates an improper voltage level on the output circuit that controls the Malfunction Indicator Lamp (MIL).

CONDITIONS FOR RUNNING THE DTC
Ignition is ON.

CONDITIONS FOR SETTING THE DTC
- An improper voltage level has been detected on the output circuit which controls the Malfunction Indicator Lamp (MIL).
- Above conditions for at least 30 seconds.

DIAGNOSTIC AIDS
Inspect for the following conditions:

IMPORTANT: If the Instrument Panel (I/P) is completely inoperative, refer to A Diagnostic System Check -Instrument Cluster in Instrument Panel, Gauges and Warning Indicators for further diagnosis. Instrument Panel, Gauges and Warning Indicators

If the ignition feed circuit is suspected of being open, observe if other lamps on that circuit illuminate.

IMPORTANT: Remove any debris from the connector surfaces before servicing a component. Inspect the connector gaskets when diagnosing or replacing a component. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion.

- Poor terminal connection-Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connection. Use a corresponding mating terminal to test for proper tension. Refer to Diagrams.
- Damaged harness-Inspect the wiring harness for damage. If the harness inspection does not reveal a problem, observe the display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the scan tool display may indicate the location of the fault. Refer to Diagrams.
- PCM and engine grounds for clean and secure connections

If the DTC is determined to be intermittent, reviewing the Failure Records can be useful in determining when the DTC was last set.

TEST DESCRIPTION
Number(s) below refer to the step number(s) on the Diagnostic Table.
11. This vehicle is equipped with a PCM which utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). When the PCM is replaced, the new PCM must be programmed.
