My car listed above gave me a warning message "check break. Hybrid
System warning please stop and don't drive" after I checked the car by the computer it gave me error C1237.
Then I couldn't drive it normally, the car almost stop. What does that error mean, and is it related to the ABS?

Your advise will be highly appreciated.
Thank you

Good morning,

The fault is for the ABS system.

This system is critical for the hybrid system as it is responsible for maintaining the hybrid batteries. If the system is not working the batteries will not last long at all.

The system charges the batteries for the hybrid system it self.

I also attached the wiring diagram for the system as well.

Be very careful if you are checking anything with the hybrid system. This system is very high voltage and if you touch the wrong wiring, you will be electrocuted.
