It's the weirdest thing, but when I start my bike with the Zumo on, the ABS faults. At first I thought it was a low battery, and even replaced it after only 3 years. Same thing with new battery. Finally yesterday after repeated occurrences I was able to isolate it to the Zumo. It's definitely repeatable. Zumo on, start bike, ABS fault. Zumo off, start bike, no ABS fault. It's a headscratcher.
Bike is a 96 R1100 RS with multiple electrical farkles and two AP-1 fuse blocks, one switched, the other direct. I thought by moving the Zumo to the switched block, it would shut off when I press the starter button, but no. Odd, because my V1 recycles on starter thumb. Zumo stays on. I guess it switches to the internal battery during the short interval when it loses bike power.
Help!
Yes! Wierd!
The only thing I can think of is that the GPS receiver is emitting RF which is messing up the ABS self test. That seems really remote - but I don't know what else to think.
