When i was driving my rx400h some warning lamps appeared in my dashboard at the same time. I went home and read the error codes immediately. Error codes P2601, c1241 and c1310 showed up. Do you have any clue what cause this problems at the same time? I hope you understand what i mean, My english is not the best.

P2601 is the oil pump/motor or ambient temp sensor.
C1241 is aux (12V) battery voltage, brake control power supply, or skid control ECU.
C1310 is hybrid brake control system.

I would start with the 12V battery under the hood - when it gets low you can see strange warnings. Especially if it's over 4 years old.

 

Ok, i hope It's so simpel. Thanks

 

Is wasn't that simple. It happend again after that i charged the battery(12v) and cleard the errors. The battery is only 3 month old. I measured the battery, and when the engine is of i have 12.5A between + and -, With the engine runnig i had 14,4A so the generator is working fine. Iknow that my front right wheel bearing is bad and need to replace. And i have a hole in my gearbox, The hole is tempory fixed just one day before this errors turned up. Can any of this faults be the problem? or have do any one have a idea what is wrong?

FYI, there is no traditional generator in these hybrids. The hybrid battery pack charges the 12V battery using a DC/DC converter.

Sounds like you have some serious damage that should be looked at by a Lexus or Toyota dealer, one who works on hybrids.

 

Did you clean the terminals on the battery...They need to be clean....
