R34 GTT no tcs no abs doesnt work at all

[Thegame1594]

my r34 gtt have some problems im trying do solve these

 

There is no abs working and no tcs and the ecu tells me there are no errors.

But the car doesnt shut down throttle even if it slips what could it be?

ECU is not the place to look for error codes relating to ABS/TCS.  There's only a handful of codes in the ECU relating to ABS/TCS and most of these are just "Oh, f**k, the other computer isn't there!"  Take it to a mechanic who has a proper diagnostic machine and interrogate the TCS CU directly.

I looked for the Abs tcs Codes and it spits out the following

 

 

84 

Engine system component fuel condition

57

Battery voltage (low)

 58 

Throttlecontrol unit system or circuit for the corn-
munication line between TCSIABS control unit and 
throttle control unit 

 

 

I have done a test on the throttle control unit and there are no errors so 58 is out of the list. And 84 I don't think so engine runs fine.

 

But there is nothing I can do about 57 I think it is a voltage problem

in the end it was a faulty Tachometer (meter control unit) that caused all of the above described problems
