Electrical Problem

[neofenrir34]

need help. i own a R34 GT25T stock (well no major mods) couple of week ago driving around not even pushing it at 2nd gear up a hill dong like 3000rpm got to the top of the hill and all of a sudden my TCS OFF, SLIP an CHECK ENGINE light all came on. but no problems with the car other wise. went back to work got the techs to put it on CONSULT an they came up with 3 things

ENGINE

IGN SIGNAL-PRIMARY (5 times)

suggested problem part 23710-AA500 engine ECU

ABS

ENGINE SYSTEM (3 times)

suggested problem part 47850-AA110 module anti skid

HICAS

CODE 54 (6 times)

suggested problem part28505-AA101 HICAS control unit

turned the car off then back on lights out still no problems

now i dont think that all of these are independant problems i am thinking electrical fault. if any one has any thoughts on the matter that would be great

your on the money, it couldnt be all the above in one hit. my bet is an earthing problem, some systems use a common earth...

It can be either or a combination, you'll have to work backwards, pull out each part, individually test it and try to eleminate each

just thought i would update the status of my car. i replaced the coil packs on the weekend an as yet have had no problems. so looks like it was coils

lucky in that case. if you can get a hold of some splitfire's i highly recamend them my car has never felt as good to drive. but on the down side it likes like the slight increase in torque has brought a weak/old clutch to my attention.

by the way, its not '6 times' or whatever - that number is how many starts ago the problem happened.

if it says 0, then its happened as the engine is currently running.

I have the same problem. HICAS, TCS OFF, SLIP and Engine Light.

Any help, does replacing the coils with splitfires work and solve the problem all together?

Thanks
