Thanks so much, Cantab!
Ah it was easy as Mike is a fellow Cantabrian who ive met and is a good bugger i remember well this issue he hadThanks so much, Cantab!
Yes, I am aware that the control board cannot be serviced. My unit works intermittently and after it sits overnight cycles flawlessly. When I crank up and ride a few miles the light pops on. My brake fluid was very dark when we flushed the system leading me to believe there could be debris or corrosion in the valves or valve body. Possibly dirt or corrosion on the connector. My plan is to pull the pump an separate the pump from the module and clean and flush the valve body and valves with CRC electronic cleaner.If the Tenere ABS block looks like that on the inside, you may get lucky and find a shorted FET that can be replaced, but that control board is potted and isn't serviceable.
If you think there is corrosion in the abs module…..what makes you think that the master cylinder is not corroded too? If moisture is going to enter the brake circuit, it will enter where it enters 95% of the time... through the reservoir cap. And the rust cannot be cleaned... you can remove it... but the metal will be damaged... The pics/link you posted are only of the electrical circuit (integrated circuit, motor, and solenoids)... the valves are "inside the abs body"How to Disassemble ABS Unit

FYI.....
One step ahead...or several steps ahead of you here. Both wheels removed sensors and sensor rings cleaned. It is very odd that I can cycle the pump, 20 or 30 times with the bike on the centerstand., I take off down a dirt road near my home and cycle the ABS every 30 yards or so cycling back front and front back as you have suggested and all goes well for about 15 minutes and I get an ABS light. When I changed the brake fluid it was very dark possibly indicating contamination in the system. If the brake fluid had "varnished" 'there is possibly residue in the valve body this could possibly cause the intermittent operation. possible residue from corrosion moving within the solenoid field.22K is so little...I doubt you'll find all that dirt and rust you're looking for...if the fault comes from the "brake pressure" side (fault 62)...you should look for that fault first. The abs is simple, if you don't use the brakes, nothing will happen…..if you start to brake (pressure and deceleration sensor) the system will go into alert….if due to that braking/deceleration pressure, one wheel turns less than the another, the abs will actuate the solenoids…..And for the UBS system, the same…if the front brake pressure sensor is activated…the abs module will press the rear brake (at a pressure according to the front pressure)….. So you have 2 pressure sensors. You should rule out which one is failing…..
Do a test, braking “only” with the rear brake….and see if the fault appears….and then the same but only with the front one (disabling the UBS, with a small touch on the rear lever)…..
What you are trying to do, is like when a surgeon decides to open you from the throat to the groin, to see what is wrong…..
Light comes on after bike warms up without applying brakes.Well, I would still ask you if the abs light comes on when you are pressing any of the brakes... or it simply comes on without pressing the brakes... and another question... where you read that fault code 62 refers to the pressure of the circuit braking?

I think you have started from an erroneous premise, regarding what you were .

Is there any way to delete the fault codes short of a dealer?Under what fault code does the light come on?…..it could be a momentary power failure, a momentary loss of signal, the pressure sensors are no longer there, because you said that the light came on without applying the brakes….if you don't delete the fault codes, the light will remain on, just to remind you that you have a fault detected and stored in memory
If you put a new module, and the fault is elsewhere, but related to the module... you won't solve the problem...
