ABS Sensor Issue - Can't Clear

[GreatWhiteHunter]

I let my rear pads go a little too long before I replaced them. My reward was an ABS error that I cannot get rid of. I've bled the rear brakes and I've cycled the ABS pump, which worked for a short time. After a ride in the driving rain the other night, the issues are back and I cannot clear them.

The issue: Error code 69 - which translates to an ABS sensor malfunction (there's more to it and searching this site will reveal it all, thankfully)

What I've done:
- cleared the codes (using just the method available on the bike as I don't have access to a diagnostic computer)
- bled all three calipers (even though I'm reasonably certain this pertains to just the rear)
- cycled the ABS pump
- pulled the sensors and looked for anything caught in the sensor holes and cleaned the sensors (just a dry cloth, no cleaners of any kind)
- repeated the bleed and ABS pump cycle

This works for a short time but it all comes back. TCS fails, the ABS light comes on and the engine light comes on. The engine light is related to that code 69 every time.

I'm going to remove the rear wheel and see if there are any obstructions/damage to the ring that the abs sensor reads but I'm posting here in case there's something else I should look for. This bike was rock solid before I changed my rear pads.

Have you cleaned the magnetic wheel located in the hub? Ive seen this (what you describe) before, and in my case there was iron "dust" stuck all over the magnet. After I cleaned it all up it worked fine...

Just a thought

Def headed there. I'm really hoping that's all it is.

So I pulled the rear wheel off. Cleaned the magnetic ring. Cleaned the hub cap. Cleaned the sensor end (just dry paper towel there). Put it all back together and it's worse. I cleaned the ring with WD40 and made sure to wipe away any residue but could that be an issue?

I'm going to take it apart again and clean everything with brake cleaner. If that doesn't work I guess I'll replace the rear sensor. Before I do that I'd really like to know how to test it properly. I just hate throwing parts at a problem.

According to the manual, 69 error points to a faulty rear brake caliper sensor

Right. And I was going by other threads here on how to fix that. Now I'm trying to figure out how to fix this the right way.

This is the thread that I was using as the primary source for a fix:

Error code 69

2016 Tenere ES error code 69. I had/have an engine knock so I brought it to my mechanic to check the top end....nothing found but now I have an error code 69. Engine light, TCS and abs all on. Maybe coincidence maybe something he inadvertently did no clue. I cleared the alarm but it comes right...

Have you traced the wiring for the rear sensor all the way back to it's connector? Perhaps the lead is damaged or there's dirt/corrosion in the connector? I've also heard a few cases, not necessarily with ABS sensors, where connectors had not been fully seated and locked (clicked) together.

Whilst I note what the manual says, hopefully this is an ABS/TCS issue, rather than a problem with the ABS module itself.

IIRC the Super10 will throw a code 69, if say you run the bike on the main stand & drag allows the rear wheel to rotate; this should then clear itself once you ride away.

Assuming the OP isn't running odd size tyres & upsetting the system, this just has to be an ABS sensor issue. Could be the rear, given the circumstances, but don't forget the ECU compares readings from the front too. There is a test regime on a 2014 bike, mentioned within Checks post on this thread, that may save wasting a few bucks ............ https://www.yamahasupertenere.com/index.php?threads/error-code-69.26871/

Yes, thank you. As noted above, this was my previous reference.

Since the condition worsened after the driving rain that I was in the other night, this is a good possibility. It's on the list of "to do's" for sure.

I finally threw in the towel on this and called the mechanic I know at the local Yamaha shop. I ended up taking it to them and he figured out that it was the front ABS sensor. I was so ready to start throwing parts at this thing, but I didn't and let them use their computer and paid the diag costs. It was worth it in the end as now I know that all is well.
