Warning code P-21, P-22 - Konica Minolta KONICA BR BIZHUB C451 1BLACK IMAGING UNIT

same as all of those from 1989 to now.
gas engines.
in the usa, on this usa forum ,btw, they sell this car world wide
with a range of engine types.
our gas engine has 2 sensors for fuel level
main and sub level, sensors yes complex.
did you scan the PCM first.? 21,22 is it. below
if yo scan it , it tells you which one is bad... for sure.

Looks like you have a few issues there.

1. The battery warning. This is indicative of a weak battery and if your battery is 3 years old or more I would replace it.

2. If you have a weak battery this can trigger other warning lights in the vehicle, typically the ABS warning but sometimes other warning lights as well depending on the electronic features in the car. If you replace the battery this should correct the battery warning and most likely the ABS warning if both of these warnings appeared at the same time.
Normally, once the ABS warning is displayed the anti lock braking system(ABS) will be shut down. Whilst your braking will be normal, if you brake too hard and lock up your wheels on a slippery road there is no ABS assist to prevent the brake lock up which you have when the system is working.

3. If the alternator on the engine is not generating sufficient power and thus not charging the battery at all, or very little, you will likely get a battery warning light. I don't know if your 1999 vehicle has a warning light to indicate a faulty alternator or not.

4. Check Engine Light.
You suggested the CE warning has been showing up for a few days and before the battery and ABS warnings popped up.
The CE warning can be caused by dozens of different engine issues.
The vehicle needs to be scanned with the appropriate scan tool to see what fault codes the onboard computer is generating because if you have a CE warning light there will be fault codes generated 99% of the time.

Once these fault codes have been pulled the mechanic can start to diagnose the cause of the problem or problems. Each engine fault code your car's computer is generating can be caused by different types of problems so it is important that they diagnose the issues correctly. Otherwise your Check Engine light will remain on as long as the causes are not identified and fixed.

Found L306 was open. B+ to pins 21,22 of PFC2 at the FC

Cont tact me for a link to the full service manual.

Yes it may be the wires are shorting or its actually the problem with instrument cluster.
Also get the vehicle scanned for any error codes stored in computer this will confirm whether is short circuit issue or actual problem:------

-------------These will help.Thanks.

its probly in the caliper. but chek 2 make sure that the ground wire is still grounded

The easiest way to reset that light is to go to an AutoZone or Advance Auto..and they have the code readers..and they will see what code you have and they will remove the codes from you car computer and reset the light for free..or you can buy a code reader and do it yourself..i hope this helps....Keith

I have a Garmin 182C and I get interfernce on VHF channels 21,22 and 83 the moment I turn on the Garmin. I have tried changing radios, antennas, placed separate poer and aground lines and nothing helps. Garmin gives me the run around.

HOW TO SOLVE THE PROBLEMS

i founfd this, it could be the problem. Symptom: NO VIDEO Cause: Found L306 was open. B+ to pins 21,22 of PFC2 at the FC. find L306, will be hard to find with all the boards, but L306 is a coil. if you can find it use a multimeter to see if it's open. 450 sound slightly high but if you have a service call or pickup & delivery it might be right. hopefully you find the coil bad. good luck.
