BF200 Overheating Issue

2007 Bf200 - steady alarm and overheat warning light comes in at 4000 rpm. Steady pee stream. Anyone have suggestions on what the problem could be? Also I know how to get the error code, but anyone know where I can find what the codes mean? Thanks
 
Send me an e-mail at [email protected] and I will send you the codes based on the MIL light blinks.

Do you have a 4-light console? If so, just to confirm, when steady alarm comes on, green oil pressure light is on, red overheat light is on, red MIL/fault light is off, and red charge/alternator light is off - correct?

Is that steady pee stream hot? Should be about 100 - to 110 degrees. Hot tub water.
 
Today I jumped the lime green/white to the black wire on the service connector. Turned ignition on, got normal 2 beeps. All four lights came on for about a second, then the MIL and the alternator lights stayed on.

In the codes you sent, there is nothing for only those two lights staying on.

Any ideas?

Thanks
 
Below is the procedure you should use.

You need to retrieve the codes from the EPROM in the on-board engine computer - the Electronic Control Module or ECM.
Takeoff the engine cover and the plastic cover over the electronics on the front of the engine. There you will see a red four-pronged female plug. Use a paper clipto shunt the lime green/white wire to the black wire – that is, the two wires that are closest to the engine when the red service connector is correctly setin its holder. If in doubt, invest in a SCS service connector, which you can order online - part number 070PZ-ZY30100.

Once connected, turn on the key switch and observe the number of blinks on the check engine (MIL) light. The blinks will repeat until you turn off the key.
If the MIL comes on and stays on without blinking, you have one of the following conditions:
• Short circuit in the service check connector wire
• Short circuit in the MIL wire
• Short circuit in the sensor system power supply
• Open circuit in the power supply line to the ECM
• Faulty ECM

If the MIL comes on, then goes off after a few seconds, there are no codes in the EPROM.
If the MIL starts blinking, then count the blinks, which will indicate the faultcode. You may get long blinks and short blinks. For example, two long blinks, followed by five short blinks, would be a fault code 25. The blink sequence will repeat itself until you turn the key off. If there is more than one fault, you will get multiple fault codes. For example, three short blinks, followed by two long blinks and five short blinks would be fault codes 3 and 25. Post the number of blinks and I will try to tell you what the error code is. Or, refer to the document I sent to you.

If you get only one blink, that repeats about every three seconds, that is a faulty O2 sensor. If a faulty O2 sensor is indicated, first check the wiring and connector. a loose or corroded connection can set off that alarm.

Latest update: The MIL comes on and stays on, so I will check for the conditions you said it could be. I hope it's not a faulty ECM. The boat is only six years old.

Thanks
 
Ok I give up. Going to take it in and get it diagnosed. The ECM and O2 sensor were replaced last year under warranty. I would hate to think the ECM failed already. Of course, none of it is under warranty any longer. I will let you know the outcome. Thanks for your help.
