    Hey Folks There does not seem to be a lot of good sources out there for troubleshooting and diagnosing ECU problems with my Massimo Buck 400 (which is also a Bennche 400 & Cazador 400 only with different badging), so I thought I'd share some info that I found during my searches the past few days. I was trying to diagnose and repair a hard starting issue. Using the following info, I was able to figure it out. My ignition coil threw a 0351 code. I discovered how to read the codes without an OBDII code reader. The following procedures should help you check your fault codes and clear them if needed. Fault Code Troubleshooting for Delphi MT05 ECM on the Massimo Buck 400, Bennche Bighorn 400, Bennche Cowboy 400, and Cazador 400 *NOTE: The MT05 ECU is not really OBD 2 compliant. It is much more similar to an OBDI system. I know this because I once converted a Suzuki Samurai from carburetor to a full on EFI system a while back and it had all of the same type of sensors as a Delphi EFI system. The MT05 ECU controls either 1 or 2 cylinder engines commonly found on Massimo, Bennche, and Cazador. Delphi EFI System Design Delphi EFI employs 5 sensors to monitor engine performance. 1. Crankshaft Position Sensor 2. Coolant Temperature Sensor 3. Oxygen Sensor 4. Throttle Position Sensor 5. Manifold Air Pressure/Manifold Air Temperature (MAP/MAT) Sensor Delphi EFI employs the following system components. 1. MT05 Engine Control Unit (ECU) 2. Fuel Pump 3. Multec 3.5 Fuel Injector 4. Idle Speed Control Valve (Idle Stepper Motor) 5. Multec Ignition Coil 6. Fuel Vapor Canister Purge Valve Using the Digital Dashboard to Decipher EFI Trouble Codes In addition to the diagnostic scan tools, you can use the engine warning light of the Siemens dashboard to diagnose EFI problems. The digital dashboard receives signals from the MT05 ECU, and the engine warning light will flash a diagnostic trouble code (DTC) if the ignition key is switched on/off for three cycles. When you turn on the ignition, the engine warning light will illuminate, which indicates the EFI system is operational. After the engine is started, the engine warning light will extinguish if the EFI system is working properly. However, if the engine warning light remains illuminated, it indicates the EFI system is not working properly, and there is a system component failure. Deciphering Diagnostic Trouble Codes To read the diagnostic trouble code (DTC), open and close the ignition key three times in rapid succession, as follows: open/close—open/close—open. At this point the engine warning light will flash a DTC which indicates the fault in the EFI system. Refer to the attached fault code table to identify the corresponding problem. The engine warning light will emit a sequence of flashing lights. If the light flashes 10 times, the translated number is 0. If the light flashes one time, the translated number is 1, et cetera. For example, if the MAP/MAT sensor is disconnected, or the connector is shorted to ground, the engine warning light will flash in the following manner (This is an example only). The engine warning light will flash 10 times: The first number of the DTC is 0 After an interval of 1.2 seconds, the engine warning light will flash 1 time: The second number of the DTC is 1 After an interval of 1.2 seconds, the engine warning light will flash 10 times: The third number of the DTC is 0 After an interval of 1.2 seconds, the engine warning light will flash 7 times: The fourth number of the DTC is 7 The resulting DTC is P0107. In my case, I had an ignition coil failure that threw a code. When I checked, it was in this sequence: 10, 3, 5, 1. The 10 represents a 0. So the actual code was 0351. I fixed a loose wire and rebooted my ECU using the procedures I detailed below. If there are other fault codes, the engine warning light will flash the next code in 3.2 seconds after finishing P0107. After all existing fault codes are flashed, the engine warning light will repeat the fault codes, in sequence, until the ignition key is turned off. To clear fault codes you need an OBDII Fault Code reader and a Delphi 6 pin connector adapter cable that you have to order from China and wait 8 weeks…or you can simply reboot the ECU using the instructions detailed below. Rebooting the ECU Perform the following steps to reboot the ECU. 1. Turn off the ignition for 15 seconds. 2. Turn the ignition on/off for 5 cycles. Make sure each cycle lasts about ½ second, verifying the start of the fuel pump for each cycle. If the fuel pump doesn't start during any cycle, begin the entire reboot procedure from the beginning. 3. Turn off the ignition for 15 seconds. Final Notes: I have included pictures of the OBDII connector and the Delphi 6 pin connector in case anyone wants to go buy your own and build a connector to use for an OBDII reader. You can do the same thing with code reading and resetting using your check engine light on your dash. But some folks want to do it with code readers. Hope this helps some folks. I have been scratching my head until tonight on how to reset my fault codes. Then I discovered all of this on some motorcycle forums. I am not a technician. I do not endorse any manufacturers. I am just an OCD driven old man that likes to work on my own crap. I have lots of time to figure things out. If you run into a problem that stumps you, give me a shout. I may be able to give you some ideas. Or maybe not. This system is essentially an OBDI and very simplistic. If you are methodical and patient, most problems can be figure out thru a process of elimination. Take care - JT

    Sorry buddy, I thought that I was clear about the wiring, and the draw. Looking back at my post, I see that isn't the case. Mine is a direct hookup, using battery cable sized wire. The engine absolutely must be running during the entire pull. It doesn't matter what kind ,or how strong, or how big of a battery. A winch at full load will empty a battery in a couple of minutes. Unless that engine is running. I've owned several vehicles that were equipped with a winch. So trust me on this. Tips to consider. A snatch block is a necessity for several reasons. Sometimes two would be better. Winching is extremely hazardous when you use wire rope. That cable breaks, people can, and have died. Get that kevlar type stuff, you'll be much happier with it. Also for several reasons. If it breaks, you only have to buy a new one. A wireless remote is the most wonderful, perfect, winch accessory. But the batteries are always dead when you need it. So...what did you decide to do about installing that thing? I've always found that they're not as handy as you'd think they would be. But there's no getting around the fact, that sometimes they're the only way out. So I put one on everything that goes off-road.

    This is solid information, on a topic that's really important to plenty of members right now. It should be a sticky, or whatever this forum calls it. So that we don't have to search for it. And it doesn't get buried beneath the chaff.

    Welcome to the forum! There was some talk awhile back, about one of those Hisun models being a Yamaha rhino clone. It might be worth checking part numbers for the part itself. As well as engine specs. You might get lucky.

    I would be tempted to weld steel plate under there if possible, they're stuck there in a vulnerable spot for a tree stump. as long as it wouldn't inhibit proper suspension travel.

    it appears motorcycle doctor has them in stock in Missouri USA, would it take that long to get to vancouver? https://www.ebay.com/itm/Crankcase-Position-Sensor-Crank-Trigger-UTV-800-HiSun-Massimo-BENNCHE-UTV800-MSU-/351251653615

    Travis, No they didn’t replace harness, I was there the day he spliced it and watched him do it. They thought they’d do some troubleshooting on it while I was present to try bypassing the seat belt safety device. After 8 weeks in that shop, they told me they replaces entire harness, in which they didn’t! I won’t take it back to that location again as I believe in honesty and they weren’t. I appreciate your opinion but it doesn’t apply on that info. Thanks again!

    I was able to get in touch with someone in the warranty dept. They sent me a new ECU, i installed it yesterday. Now it runs great,over 40mph no problem.

    Battery voltage may not be the issue. The issue may be what the amps/wattage of each battery is under load. Have your dealer run a load test on each battery to see if they are up to spec. A battery can show its rated voltage but fail under load. Today I was splitting logs in my pasture and pulled my log splitter and a full load of split oak logs in the bed up a steep bank in 4wd and in low without any problems.

    I am sorry you have had the issues list. I have a friend that has had an E1 for about a year and he had a battery issue since he brought it home. They finally fixed it by replacing one faulty battery. I have had mine just six + weeks and it has more power than I need. I have small mountain at the back of my place and it goes up it like a jack rabbit. Haven't gone through any heavy mud yet so no experience.

    sometimes it can take time for the rings to properly seat... I remember when i rebuilt my mule, it would blow a small amount of smoke on start up, but went away within a few hours and doesn't use a drop now. Did you have to Hone the cylinder, or have a machine shop bore it out? Could also be valve seals leaking.

    Did a quick search for good coolants to use On Aluminum head engines, a lot people seemed to like Prestone green coolant. Or the Prestone 50/50 We run prestone in our 70HP tractor, Dodge farm truck, and any other liquid cooled engine.
