JD425 with the Kawa and at 1,000 hours, crappy plastic cam gear broke- right on schedule! Rebuilt with steel gears, and still running fine after 300 hours. Mechanic said, "typical"!

"why does a riding mower need CANBUS ?" Very good question! Guessing that the government elected to, "protect the public" and requires all the safety gadgetry. Manufacturers thought CANBUS would make that easy for them. Also, brings in cash for dealers that service these computerized marvels...

How was this resolved?

Appreciate that info! Did the harness come with those instructions, or just what you figured out? So it just checks the battery? What about all the other failure modes? Anyway, too late for me. Gutted my mower, with only deck motor and traction motor remaining. I'll figure out controllers, and...

You have obviously been in the electronics repair business by your comments- me too. Next I have to figure out the wiring of those Hall effect devices from the wires coming from the Deck motor. Then I could use a generic BLDC motor controller. ($50). Any ideas on how to identify those wires...

Looks like you're getting to hate this digital system as much as me. What is this, "breakout cable"? Is it just for your zero turn mower, or generic? So you must have a port you can connect to? That's cool! You've probably tried disconnecting/connecting the battery from the system to perhaps...

Agreed! Reading (sniffing) CANBUS codes is like asking for national secrets. No idea where the port is (if there is one), and how helpful (or not) they can be. That's why I gutted the entire existing system down to the deck motor, the traction motor, controllers, and the battery. Rebuilding from...

Best of luck. Funny, my 2018 Craftsman E150 Electric uses the same control panel. All made by MTD.

The motor controllers need the CAN to enable motors, but my motors themselves don't appear to be involved. Seem to recall this old boy was made in 2018. Will keep you posted!

Correct! Found they are Brushless DC motors (BLDC), requiring 3 inputs to drive it. Now to figure out the Hall-effect wiring which is necessary for the controller to control speed. What complicates this relatively simple concept of battery and motor to make things work is that pesky CANBUS...

Never have seen an error code on the simple little display on the mower. Just, "Depress Brake Pedal", "Close charger Door", etc. Anyway, it's done- spent this holiday gutting the wiring. Down to a cutter motor, and a drive motor. Now just need to drive the two. Interestingly, both motors are...

Thanks! There's no code from the VCM, or the mower. The mower simply does nothing with the switch to ON. The only error code is from the Delta-Q charger- E004 Tempted to gut the wiring harness, and use 48 volts to the blade motor, and the drive motor controller to drive the drive motor. Simple!

Thanks for the explanation, but what is the , "PDM"? Also, do you know what this black odd-shaped box is? Has a 4-pin connector, a 12-pin, and the large power cables.

I notice the XT1 wiring diagram is missing some components like the motor controllers, 20 Amp fuse, and the 4-pin CANBUS connector on the battery. Are there other schematics from your source? Thanks again!

Live in a swamp, so no nearby cliff to push it off of.
