Hello everyone
I have a...rather curious issue with my 2004 BMW r1150rt. As the title says, I replaced an old AGM battery with a new "Battery Tender" (Deltran) LiFEPO4 motorcycle battery (Part # BTL14A300CW).
Previously, the bike would start up, albeit slowly due to the dying battery. Now, the bike activates ABS, flashes the brake light, and the red hazard light is lit right underneath.
I pulled codes via GS911, stating the following:
3 fault codes found:
821 Hall sensor 1, no signal - this fault will always occur if engine not running or engine not cranked before reading Fault codes.
The fault is currently present.
288 Throttle Position Sensor, Internal Fault on Upper or lower Potentiometer Slider.
The fault is currently present.
901. Hall sensor 2, no signal - this fault will always occur if engine not running or engine not cranked before
reading Fault codes.
The fault is currently present.
I also attempted to calibrate the throttle, but kept getting the error that the idle switch was off. I am unfamiliar with exactly WHAT an idle switch on this bike is. Google searches discussed the choke cable on the left handlebar, so I loosened the cable until there was slack, to ensure the choke wasn't on. No change in error message.
But, here's the most interesting part. With the key in the "ON" position, NONE of the handlebar inputs work. Blinkers, hazards, horn, windshield adjustment, headlight beams...nothing! Previously, I could turn the key to the "ON" position and perform most of these inputs with the engine off.
I had removed ALL of the fuses (wasn't sure where #5 fuse was, from left-right, or right-left looking at the fuse cluster), and let the bike sit for an hour. I then replaced the fuses from the outside in, ensuring that either #5 fuse would be the last insertion.
Still no joy. Handlebar controls are still non-functional. Starter doesn't engage. The kill toggle switch works, turning off the transmission shift notification on the LCD and causing the ABS to go silent. I tested turning the bike on in neutral with and without the side stand extended. Pressing on the brake lever when the key is in the "ON" position does activate ABS; ABS doesn't appear to be negatively impacted by this issue.
Further, GS911 was able to give me the ECU software number and other information on the ECU. In my experience with BMW cars, if a DME (e.g. ECU) is bad, INPA/ISTA cannot read it period. I think that the motorcycle ECU should behave in a similar manner?
Anyways, I'm at a loss at this moment. I took off the left-side tupperware again, just to verify TPS cable is attached. Again, NO connections, except for air box, were disturbed during the replacement of batteries. And yes, I charged the new battery before installing.
I am eager to hear any thoughts on potential issues I should check.
Thank you everyone!
Mike
