Alot of TRAC trouble codes in my ls400 :-(
 

Hey guys

The TRC light in my dash are constant ON.

I checked the codes at http://www.lexls.com/tutorials/intro/codereading.html

I have both Engine codes and TRAC codes.

Engine: 21, 25, 26.
Trac: 13, 46, 51, 52

I took aout the 20 amp fuse to and took the car for a spin hoping that the fault codes was just old ones never deleted.

The Engine codes are now gone, but the TRAC codes are still here, so theres something wrong. But the code: 46 was now 47. Dont know if i read the first reading wrong maybe but well here the codes are:

13 - Open in TRAC throttle relay circuit

47 - When idle switch is ON, sub-throttle position sensor signal is 1.45V or higher

51 - Problem in engine control system

52 - Brake fluid level warning switch ON


So what do i do know? The only code i understand is the last one i think. I checked and the brake fluid is at its high level so no problem there. Is it the contact that are broken or?

I hope you guys can help me. I'm from Denmark so sorry my bad spelling sometimes. I can read most English, and some technical also. But i need some help here hehe. :sad:
