Hi all. 2006 Norge with ABS (first year model, 2v) 60,000km on the clock (plus recent "extra")
30 minutes into a 3 week and 2500 km trip the ABS light flashed on, the speedo dropped to zero and the "SERVICE!" error came up on the dash. Apart from an occasional flicker of the speed and odometer, it was pretty much no one home. And - I found out the hard way - the ABS is no longer working.
Every time I turned the ignition on, within seconds the ABS + warning light came on. Rarely there's a flicker.
A weird addition was an hour after the initial fault, the fuel gauge also went stupid, but it came good after a couple of hundred kms' and been no problem since.
Fault-finding done so far:
- all fuses checked for continuity, and the fuse holders inspected for corrosion. Nothing seems to be amiss.
Armed only with my eyes (and simple tools) and a multimeter ... (no, I don't have a spare dash to swap out ... and besides ... #codes)
- How do I check to see if the front and rear speed sensors are at least producing a voltage that the ECU can read? What's an easy way to take a reading? This will tell me if the sensors are the problem or look elsewhere.
- Where's the ECU multipin connectors to see if they're seated correctly? The fuel gauge going stupid the once is suspicious...
- In what way does the speed sensors affect the ABS? How does it work: do the speed sensors feed into the ECU and in turn the ECU controls the ABS? That ABS has been really handy and I don't want to live without it.
I've been going through the archives here, and nothing is feeling like it's the same situation as me: it's not ingress because it's been 3 weeks of hot weather with very little rain. Slow onset of corrosion may be possible, as might wiring damage. I'd hate to think a new ECU/dash is needed: there are no 20 year old Guzzi parts to be had anywhere near me.
Thanks in anticipation
