Hi. HCH owners and sorry for my bad english. I have a HCH 06. I live in Mongolia.Here, the winter average is -15 degrees to -20.Mornings start IMA light Engine Check and 12V battery light transmission D light flashing.30 - 40 minutes to be heated, D light switched off first.Then turn off the ignition of the IMA battery and the light switched off.Diagnostics for
- Ima internal circuit malfunction
- Motor rotor position sensor & motor rotor current sensor malfunction
- Lost communication BCM to MCM, etc.
If anyone had such a problem, please help me

 

does the car drive like it has problems? or are just the sensors going crazy??

when the motors are that cold the oil does not flow like it should, in the transmission and in the engine. the sensors will detect a problem but when the car warms up they should clear.

that is crazy cold!!

 

do you use a block heater? That would help

 

i operate heavy equipment for a living and we see the engines throw all kinds of fault codes in extreme cold. the cold is very hard on the equipment but I don't have to tell you that! you live in Mongolia! usually the codes clear up after the machine returns to normal operating temperatures.

I'm with hunter, I think a block heater would be a great help. it won't cure all, because your electronics in the ima will still be subject to the extreme cold, but it should help with the codes regarding the engine.

 

thank you for all replies. One of my friends, and with such hch 06. His car starting no problem in extreme cold.
there is no official dealer of Honda

I do not know what to do

 

Is the 12V battery tested good? If the 12V battery is good, can you disconnect it for 30 minutes and re-connect. This will reset all the errors. Also, can you temporarily bring the vehicle into a warmer building so you can rule out the cold from these issues?

 

I did it . the problem was unsolved, lights coming again. When car is staying in the warm place lights out
