Title: Do these fault codes indicate a faulty ABS unit?
Post by: hjsgs911 on October 08, 2015, 11:35:02 PM

I got the red 'brake failure' light today on my '07 R1200R together with these fault codes:

41704 KL30 (Battery positive) under voltage
The fault is not present now.
24052 Electrical System under-voltage
The fault is not present now.
24048 Power Supply to Pump motor faulty
The fault is not present now.
24049 Power Supply to Pump motor faulty
The fault is not present now.

Does this sound like the ABS pump? Are those the faults others have seen who then ended up having the pump fixed or replaced? Could it be the battery or something else? Can I do additional tests to make sure I do not unnecessarily take out the unit and send it to Module Master?

Stating the model of the bike would be of assistance but the codes are telling you in general that battery voltage was low at some point and it is not now

The 24048 Power Supply to Pump motor faulty error can occur due to the somewhat common stuck brush issue with the motor for the ABS unit.  See http://forum.hexcode.co.za/forum/index.php?topic=2.0

Thanks. Yes, likely the stuck brush problem. Will deal with this when the colder days arrive. Perfect time for that.
