2001 KIA Sportage shows a P0650 MIL Ind Lamp malfunction (control circuit) is the PCM bad? light does not come on ever.or is there some test to try ? I would appreciate any and all ideas. thanks

How does the vehicle run ?
Malfunction Indicator Lamp (MIL) Always On
Circuit Description
Ignition voltage is supplied to the malfunction indicator lamp (MIL). The powertrain control module (PCM) turns the MIL ON by grounding the MIL control circuit.
MIL Operation
The MIL is located on the instrument panel (IPC).
MIL Function ?€¢
The MIL informs the driver that a malfunction has occurred and the vehicle should be taken in for service as soon as possible.

?€¢
The MIL illuminates during a bulb test and a system test.

?€¢
A DTC will be stored if a MIL is requested by the diagnostic.

You could have a bad instrument cluster ! Here is part of diagnostic flow chart for your vehicle !

1

Did you perform the Diagnostic System Check-Engine Controls?
Go to Step 2
Go to Diagnostic System Check - Engine Controls

2

1. Turn OFF the ignition.
2. Disconnect the PCM.
3. Turn ON the ignition, with the engine OFF.
4. Observe the MIL.

Is the MIL illuminated?
Go to Step 3
Go to Step 5

3

1. Remove the instrument panel cluster (IPC). Refer to Instrument Cluster Replacement in Instrument Panel, Gages, and Console.
2. Test the MIL control circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?
Go to Step 6
Go to Step 4

4

Replace the IPC. Refer to Instrument Cluster Replacement in Instrument Panel, Gages, and Console.
Did you complete the replacement?
Go to Step 6

5

Replace the PCM. Refer to Powertrain Control Module Replacement .
Did you complete the replacement?
Go to Step 6

you need to check the bulb in the dash see if its good check for power at the plug for the obd

P0650

Description
Malfunction Indicator Lamp (MIL) Control Circuit Output drive moduels (ODM's) 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 whish the PCM is commanding ON. Unlike quad diver modules (QDM's) used in prior model years, ODM's have the capability of diagnosing each output circuit individually. DTC P0650 set indicates an impropervoltage level on the output circuit that control the MIL.

P0650 - Malfunction Indicator Lamp Control Circuit Malfunction

Possible causes- Harness or connectors for the MIL circuit is open or shorted. Check connectors to instrument cluster.
- MIL bulb may be faulty, check this first.
- Faulty ECM. Very rare that this is the problem.

MIL CONTROL POWER CIRCUIT OPEN IN THE INSTRUMENT CLUSTER, THE MIL LAMP IS DAMAGED OR HAS FAILED,THE INSTRUMENT CLUSTER OR THE PCM HAS FAILED.

DTC P0650 represents an issue with the actual check engine light (malfunction indicator lamp). Ignition voltage is supplied directly to the malfunction indicator lamp (MIL). The powertrain control module (PCM) controls the lamp by grounding the control circuit via an internal switch called a driver. The primary function of the driver is to supply the ground for the component being controlled. The driver has a fault line which is monitored by the PCM. When the PCM is commanding a component ON, the voltage of the control circuit should be low, near 0 volts. When the PCM is commanding the component control circuit OFF, the voltage potential of the circuit should be high, near battery voltage. If the fault detection circuit senses a voltage other than what is expected, the fault line status will change causing the diagnostic trouble code (DTC) to set.

A DTC P0650 indicates a problem with the circuit to the actual check engine light itself. If the fault is current, check if the check engine (service engine soon) lamp comes on when you turn the ignition on, If not, we will need to pull the engine control computer and ground the wire that goes to the light. If the light comes on, it is a failed pcm which must be replaced and reprogrammed. If not, it is either the circuit to the cluster or the cluster itself.

Good luck.

error p1446 is a closed control valve on evap .. that is located behind the tire on the drivers side .. you can sometimes clean that .. that can also be caused by a bad or loose gas cap ..

code p1456 means a small evap. leak .. there is a smoke test to help find the leak if you have trouble ..

P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:

Harness or connectors (MIL circuit is open or shorted.)

MIL bulb may be faulty
