Hicas Problem

[lukey92]

Hi all having some trouble with my hicas, have done diagnostics and it's 4 1 second interval flashes then 3 long then 2 short then 1 extra long,can anyone help me with the code what is it? Thanks

The sequence you describe does not make sense.

Pages CH348 + 349 of the R32 GTR manual tell you that it should give error codes in numerical order. So if you do have a 2 flash and a 3 flash code, they should come 2 first then 3. Not in reverse order like you describe.

Just FYI, 2 is LH solenoid output (which is one half of the unit in the engine bay) and 2 is the failsafe valve (which is in the rear). 4 is the code for power steering solenoid output.

You should get it onto a proper Consult unit to read the codes more easily. There's definitely something wrong.

Forget trying to diagnose it, just rip it out and forget about it.

Yeah its weird I'm going to see if I can get it checked out today

No luck no one seems to know how to fix it going to nizpro performance tomorrow hope they can help

You just need a mech with a scan tool.

Went to nizzpro performance they had a second hand hicas computer, put it in all good no more hicas light when I'm driving anymore, did diagnostics after instilation and still getting a code from the hicas light, instead of being 4 1 sec interval flashes 3 long 2 quick and one extra long it's now - 4 1 sec interval flashes 1 long 4 1 sec interval flashes and one extra long???

Get the manual. Compare with the pictures on the pages I indicated. We'll never be able to work it out from your descriptions. "Super long" means what exactly? And you need to take careful note of the starting point in this sequence. None of the sequences in the manual start the way you describe.

Ok will have to get one then, super long as in light stays on for like 5 seconds and long for 3 seconds

Ended up being the fusible link on the battery leads!
