Aside from getting into an accident and having your wiring harness severely damaged, the other likely suspect is your PCM. These codes are not related to each other and indicate a much larger problem.

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.

P1661 - MIL Control Circuit

It may be a fuse or loose wire....MIL stands for Malfunction indicator lamp

The shop who failed it should be able to fix any issue with it as well.

If this answer helped please vote for it!

and what is he bpt?? what does that refer to?

Trouble Code: P1693 (2.0L L4 VIN 3 Auto)
MIL CIRCUIT MALFUNCTION Print this code data Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details

• CCM Details
• MIL Details

Trouble Code Conditions:
KEY ON, AND THE PCM DETECTED AN UNEXPECTED VOLTAGE CONDITION ON THE TCM TO MIL CONTROL CIRCUIT DURING THE CCM TEST.
POSSIBLE CAUSES:

• MIL CONTROL CIRCUIT IS OPEN
  
• MIL CONTROL CIRCUIT IS SHORTED TO GROUND
  
• MIL CONTROL CIRCUIT IS SHORTED TO SYSTEM POWER (B+)
  
• MIL "BULB" IS OPEN OR MISSING
  
• PCM HAS FAILED
  

Possible Causes: (n/a)
2000 Kia Sportage - G 2.0 DOHC - POWERTRAIN - P1693 Malfunction Indicator Lamp (MIL) Control Circuit

Search/Research revealed cause is: a. Open or short between MIL lamp and ECM b. Bad MIL lamp c. Bad connection of connectors/bad wiring
This is unrelated to the incident you describe. It is possible this momentary REVERSE polarity might have damaged the Engine Computer (ECM - engine control module). Best solution: Tow vehicle into nearest Hyundai Service Center and pay diagnostic fee. This way you'll know EXACTLY what the problem is and what's required to fix it (Parts, labor, tax, time-frame, etc.).

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
