2010 R1200RT. First fuel strip failure at 28,000 Km. Zapped successfully. 3 More failures after that, also zapped successfully. Last month (70,000Km) failed again. Zapping could not fix.
Connected GS 911. No Fault codes.
Logged real time values over 3 days. See below. Values never changed during 30+ second log sessions.
Fuel strip heater current (mA) Fuel strip heater voltage (V) Fuel sense voltage (V) Film sensor heating (%)
8,63 0,46 0 0 53,302 Calc KOhms?
Fuel strip heater current (mA) Fuel strip heater voltage (V) Fuel sense voltage (V)
0.69 0.02 0.00 28,985 Calc KOhms?
Fuel strip heater current (mA) Fuel strip heater voltage (V) Fuel sense voltage (V)
1,04 0,02 19 230,77 Calc KOhms?
Is the drastic change in values due to defective ZFE? Is my resistance calculations correct? Why drastic change in heater current, voltage and calculated resistance?
Did some Googling. Came across the ‘Spoofing’ thread and tried it.
Made up temporary spoof circuit and connected to test before finishing off. No success. Warning still on. So never completed the circuit as intended.
I’m not about to cover up the warnings on the dash. Would also prefer to get away from fuel strip.
Considered swap from film to float/lever type. The RT’s fuel tank cannot accommodate the lever sensor. Decided I would sacrifice fuel tank gauge and remaining range if I could get rid of the low/empty fuel warnings and not replace ZFE. At age 72 I no longer do very long rides without stopping and always fill up after typical 300 Km day rides at local garage at end of ride.
Googled some more. Got lever setup resistance full and empty that was posted on another thread.
Stripped, removed battery and got an auto electrician well versed in de- and repining PCM plugs. Stood by while he did the changeover (pin 34 to 21 and 35 to 37). Did a continuity test with him before he left.
Replaced panels and battery. Used the GS-911 to do the coding from film to lever type. Was completed successfully and ZFE shows… Lever. In order to test, made up temporary adapter with 2 off 5 Watt 33 Ohm resistors in series over pins 2 and 3 for hopeful half tank. (Measured 71 Ohm)
Still nothing. Then used a single 22 Ohm resistor. Still nothing.
1. Although there are no fault codes or other malfunctions, can the ZFE unit be at fault?
2. Is there something within the CANBUS that causes the latter not to work?
3. I like to believe that the repinning of the plugs are good. Will check if the answer to 2 above is negative
4. Any other advice will be highly appreciated.
