I have a 2005 Ranger 700xp. When I try and start it up the first time I turn the key to the on position no lights on the dash come on and I get nothing when I try to start it. The next time I turn the key to the on position the lights on the dash come on and then when I turn the key on to crank it I get a clicking noise from the solenoid. I had my neighbor come over and look at it and while doing this we noticed that the check engine light was flashing some codes. Neither one of us can decipher the code(s). Can anyone help? I took a video and uploaded it to youtube. Any help would be greatly appreciated on the code(s) or the starting issue. I am assuming that one of the codes will lead me to the starting issue. Thanks for ay help!!!!

test your battery, and make sure your cable connections are tight.

That flash from the SES light is too fast to read. almost makes me wonder if it's flashing like it's got a loose connection?

Check the simple stuff first. if it doesn't have power to crank, then the flash codes are the least of your worries.

My neighbor is a car mechanic. He checked all the simple stuff to no avail.

I would pull the plug on the ECM (silver box with fins ) under the hood and see if pins/wires are burnt/melted.......

Yep, I think it's the two wires in the upper left hand corner of that plug that can tend to melt? then as I recall, nothing will work. Maybe could be a bad ECM as well, but it's hard for me to remember if the ecm has anything to do at all with the starter circuit?

When the ECM fries the internal PCB, you can jump the starter solenoid and it will spin the engine but it won't start( No ECU/EFI/FAN etc.). Sometimes when the wires/pins short in the plug, it doesn't blow the ECM , at least not right away, and at least a temporary repair can sometimes be made. Then there are some that show no signs of shorting/burning the connectors and the ECM is dead as a post. No test is available to diagnose as far as I know,only "borrow a known working one and plug it in." I have seen a undated TSB on them for everything but a Ranger so Polaris is aware of the problem. Thanks to Downeaster..............
Bad ECM recalls
[HR][/HR] Dear Polaris ATV Owner:

Polaris Industries of Medina, Minnesota is revising and expanding prior Safety Bulletins ATV-05-01, ATV-05-01R, ATV-05-01T, ATV- 05-01L, and ATV-05-1C under a newly issued Bulletin ATV-08-01. The Bulletin/recall affects select Model Year 2004.5, 2005 and 2006 Sportsman 500s, 2005 Model Year Scrambler ATVs, Model Year 2005 Sportsman 400s, Model Year 2005 and 2006 Scrambler 500 4x4s, 2006 Sportsman 450s, 2005 Sportsman 600s, 2005 and 2006 Sportsman 6x6s, Carbureted 2005 and 2006 Sportsman 700s, and Carbureted 2005 Sportsman MVs.

Our records indicate that you are the current registered owner of an affected unit which needs to be repaired by a Polaris dealership. It is important that you contact your dealer to make arrangements to get this repair completed immediately.

Polaris determined your ATV was assembled with a possibly defective Electronic Control Module (ECM). Polaris has determined the recall defect could cause the ECM to fail and overheat. If this were to occur, excessive heat could cause a fire, possibly resulting in severe injury or death. Consumers receiving this notice may have already been notified about this recall and may have already taken their ATV to an authorized Polaris dealer for repair. However, this notice is to inform you that Polaris has revised and expanded the recall VIN range and is now requesting that previously used potted ECMs, used on the above affected models, be replaced with new unpotted Die-Cast ECMs.

YOUMAYCONTINUETOOPERATEYOURATVUNTILSAFETYBULLETINATV-08-01HASBEENCOMPLETEDBYFOLLOWINGTHEINSTRUCTIONSBELOW.

Until the current repair can be completed, consumers must disconnect the negative (black) battery cable from the battery when the unit is not in use or left unattended. Your Polaris dealer has received a Safety Bulletin, ATV-08-01, that describes the necessary repair procedure. This repair will be performed at no charge to you. It is possible your Polaris dealer has already contacted you and made arrangements regarding the replacement of your current ECM with a new Die-Cast ECM. If you have made prior arrangements to have your unit brought to a dealer for repair, no further action is required on your part, other than to disconnect the negative (black) battery cable from the battery when your vehicle is not in use or left unattended. If you have already had this repair procedure performed and your ATV is currently equipped with an unpotted Die-Cast ECM, please disregard this notice as no further repair is necessary.

This notice was mailed to you according to our most current registration information. While your Polaris ATV dealer is in the best position to answer your questions, if you have any questions your dealer cannot address, you may call our Customer Service Department at 1-888-704-5290.

If you need assistance contacting a dealer, please call 1-888-704-5290 or visit the Polaris web site at www.polarisindustries.com.

We apologize for any inconvenience this may cause you. Sincerely,
Laurie Rengel
Manager, Service Dealer Development & Warranty

Ok guys, I ran the video with the code flashing several times and I get the following codes:

54-----------Temp lamp....basically a nothing code
23-----------RAM Error.....Defective ECU
61-----------End of Diagnostic Check

Can anyone else verify? It is looking like a bad computer at this point.

I checked and didn't see anything that looked melted. Looked good to me :confused::confused:

Did you unplug it? rarely will it looked melted from the outside.

Those codes were blinking so fast it was hard for me to decipher. I'd say a new ECM might be a good start. especially if nothings working. the ECM was the heart of those old machines, everything went through it.

The first flash codes end in a 4 and 54 is the only one that does. The 23 and 61 flash group is pretty straight forward. I got a major headache from staring at it so many times though...............

Ok double checked and they both look good. I also am not sure why I thought it was an 05, it is actually an 06. Another question, when I get a new ECM is there anything that needs to be programed or do i just unhook the old one and hook the new one up? Is it best to buy a new one or look for a used one on ebay? Thanks for all the help!

ahh it is an 06? If so then yes, a bad ECM is most likely your problem. Should have been a re-call from polaris on those things since everyone I know that had an 06 has replaced at least one ecm

The new ECM is plug and play. no programming needed.

Last I heard you could buy a new one for $450 or so. I wouldn't gamble with used unless you can get them cheap.

Yeah, that's one of those things I wouldn't buy used unless you know the person and it comes with a guarantee. That ECM only works on the '05 and '06, so any that you buy are subject to be defective.

Just priced a new one for $261.29......part # 4011090.

Jerry , the second flash code right before 61 is a 23 which is
23-----------RAM Error.....Defective ECU
61-----------End of Diagnostic Check

Well, that "sort of" makes me wonder if it's the ECU that's defective and not the ECM, but.......

Although a defective ECU is "possible", it's by no means common.....and especially not on the '06. The '06's were notorious for toasting ECM's and the wires leading to them. The most prominent reason to believe it would be a defective ECM versus the ECU is that I'm fairly certain the ECU has absolutely nothing to do with the starter circuit. The ECU controls only the EFI parameters.....the ECM controls nearly all other electrical functions (fan, lights, AWD, starter, voltage regulation, etc....).

If there's any doubt, I've got a good ECU (I ran a Sportsman ECU in mine) that I'll let you borrow to test it with if you wanna pay shipping both ways. Just shoot me a PM if you're interested.

If somebody ever finds a place that can repair them, I have 2 defective ECM's lying around in my spare parts bin.

Another thing to check before buying the ECM......

Take the ECM apart and look for a burnt rectifier. I've tried replacing the rectifier that was noticeably burnt, but that didn't fix it....so there was probably some other damage that I couldn't see. Somebody that was really good with a schematic of the ECM could probably trace the issue down, but I'm unfortunately not an electronics genius.
