RXT 255 IS IBR LAMP C2146

[Amgfactory]

Hello everybody,

at first sorry for my english.
Im from germany but we dont have such a good jetski network

I bought this Summer a RXT255is.
Had a few problems with the engine but i could fix them.

My Last Problem was that the speedometer needls didnt rise up. So i pulled out all the cables in the front and checked them.

From this Time when i Start the Jet i have a Long beep and IBR light up.
Its showing me the fault Code C2146

When I hold down the brake lever and turn on the ignition, the light stays off.

So i changed the brakesensor but the Problem is the Same. I checked all the Cables with my multimeter - all are okay.
Fuses and Battery also good.

I called my seadoo dealer, he said that we need to change the IBR Module
Cost in germany about ~2200€

I cant imagine that after pulling out the cables the IBR Module is broken.

I would be very thankfull for any help of you guys. Thank you!

C2146

IBR

Brake Lever Sensor (BRLS) signals A/B reading difference


Damaged sensor, damaged circuit wires, damaged connector or damaged iBR pins.

Fault detected when the engine is running or stopped.

Check for 0,5 to 3V on pin F and 0,25 to 1.5 on pin C.

Sounds like you have checked all of these, just make sure there are no corroded connection pins.

Definitely a coincidence the IBR error and cable pulling. Did you have the battery disconnected when you were pulling cables? That’s the only thing I can think of.

Hi thank you for your answer.
No i forgot disconnecting the battery before pulling out the cable.
I checked all but have no more idea

Well the dealer is probably right on this one, I did read somewhere that disconnecting the battery and clamping the red and black battery cables together to drain all the capacitors in the module has cleared IBR faults. Might be worth a try, and absolutely make sure your battery is good under load, bench test, the IBR fault system is very sensitive to detect a low amperage situation.
