I gave my 2007 RT a major service a month ago (not sure it's relevant) oil, filters, tyres, brake pads, brake fluid, final drive etc etc for an upcoming trip to Morocco in a few weeks.
Today, I took the bike out for a spin, after riding for about 45 mins on fairly bumpy roads, the brake failure light came on.
The brakes continued to work fine, but when I tested the ABS on the back wheel at slow speed, it wasn't working, the wheel locked up.
I rode the bike home and plugged in the GS-911 and I got the following codes.
24052 - Electrical system under-voltage. The fault is not present now.
24048 - Pump motor defective. The fault is not present now.
24049 - Power supply to pump motor faulty. The fault is not present now.
I cleared the fault codes and ran the Output Tests with the GS911, Pump Motor and 5 valves and also did the ABS bleed test, everything worked fine.
I also checked the wiring to the sensor at the front left brake disc, it's fine, not rubbing.
Then I took the bike for a 10 minute ride, the brake failure light stayed off and the ABS was working, I tried to lock the back wheel and it kicked in.
The battery seemed to be working fine, I boost charge it with an Optimate every fortnight when am not riding it.
This was done about a fortnight ago, and it seems to start as normal this morning.
Any idea what could have been wrong?
Am worried it might happen again on my trip.
But at least I still have brakes if it does (I can live without ABS)
I previously had a 2005 RT (whizzy servo brakes) when a similar problem occurred, the only difference was that I had only about 10% brakes which was scary when it occurred on a motorway at speed.
The reason I changed my 2005 RT for a 2007 was that I thought the brake system was much more reliable!
