U0128

[OverHillAndDale]

What started as a simple project has turned kind of ugly.

I installed (successfully) a pair of USB ports on the switch panels between the middle switches. Looks great, the USB ports have power, and I successfully tested all of the switches before I reinstalled the panel. I put it all back together, all was well.

Then today I was preparing to go for a ryde, and I couldn't disengage the parking brake. I re-diassembled the byke (is that a word?), dug down to the switches and tested the circuits - all is well. I get lights on all the switches, and the parking brake circuit is working properly.

Tested for error codes and got a "U0128". A GM (or Ford?) site lists that as a failure to communicate with the parking brake module (seems likely), and LaMonster's PDF file says "Missing CAN ID 460h from WPM/EPB.Module internal error. Damaged circuit wires or damaged module pins."

I disconnected the USB port wiring, pulled all the fuses looking for a bad one (there were none), retested with the same issue. The error code is a bit meaningless to my shade-tree mechanic level of expertise.

Short of having the byke towed to the shop - anyone with any brainstorms?

You have another posting where the windshield is no longer working either, correct. The WPM, Windshield Parking Brake module is that whole assembly that the windshield motor is mounted to. If the windshield doesn't work, the parking brake doesn't work. There are a few instances on here where that fails. You might want to recheck the work you did in the switch area for anything left unconnected or damaged, but you may be looking at a module replacement. Do a forum search for windshield module and you'll come up with some history. Maybe you can contact those owners and get more scoop on it. Hard to tell if anything you did fried it or not.

Thank you - that is extremely useful.

Several have asked me to go back to where I started and disconnect my new USB ports - I have done that already. I'm going to look further into the windshield control now.

Thank you.

YOUR ERROR CODE

:banghead::banghead:..... Did I miss something .... what does a Ford or Gm code have to do with the Spyder codes ....:dontknow: ... Mike :thumbup:

 

[Highwayman2013]

I couldn't find that code on the spyder codes app. My advice is to go back and check any connections you had unplugged for bent pins inside or pinched or damaged wires.

 

[OverHillAndDale]

Already disassembled and check every connection and every (likely) place I might have crimped a wire.

I haven't pursued it to confirm one way or another but I kind of think there is a uniform set of codes for all vehicle ECMs for anything that is related to emissions control. All vehicles cars and trucks have the same I/O port to read codes. I've noticed a similarity between Spyder codes and auto codes which is one reason I think they are the same.

I had it more or less correct! http://www.totalcardiagnostics.com/...ricmanufacturer-obd2-codes-and-their-meanings

Doesn't both the windshield module and the parking brake module run off the same relay/fuse? Just a thought. Bruce

They also have a CAN_Bus, and some of the codes are the same.

It was mentioned earlier the Windscreen motor and Parking Brake share a common circuit. Have you tried to start the engine and raise and lower the windscreen.

Does it work properly or has it failed also.

Consider also, and you might need to search and research this, there have been reports where the parking brake micro switches have been dislodged. Because of this, the parking brake may get an erroneous signal. Things can happen and possibly one was bumped accidentally during your work sequence.

Any idea where these micro switches are? I've scoured every switch and fuse, every connector I can find.

I just read in the manual that some conditions are resolved by simply removing the key and waiting for 20 seconds. I have left the key in during this entire (painful) process, so I'll try that tonight.

This looong ordeal may have cured my desire to keep farkling.... maybe.

 

[Highwayman2013]

Are you sure this is the code?

 

[OverHillAndDale]

Yes, I checked multiple times. It didn't show up on any of my apps but I found a .pdf that LaMonster posted that included that code.

On the pulley assembly for the brake cables?

Try the key, but still, did the windscreen motor raise and lower the windscreen. It may seem minor but is a key troubleshooting item. Actually a very easy check and first to accomplish.

Windscreen motor never even stuttesr with the motor running.

That's cool, but I don't use Spyder Codes.

Well, good luck.

Not exactly certain what stuttesr means. In simple terms, does the windscreen motor operate correctly?

 

[OverHillAndDale]

That was phone typing for "stuttered"! No, the windscreen won't budge and the is no indication that the motor is even trying to run.
