People With Consult Cables

[nicr4wks]

About a year a go Dohmar, jrm and myself had a bit of a discussion about consult in another thread, specifically HICAS.

Tonight I was bored enough to whip everything out and have another play around, I can initialize the hicas ecu fine and went on to scan registers 00 through FF, but this only returned 1 valid register, 0x01 which seems to be a speed sensor. So perhaps on Skylines we don't get the extra diagnostic information available on the 300zx ecu (steering angle), or maybe my hicas ecu isn't happy, or maybe i'm just wrong.

If anyone is still interested in investigating this, would you like to scan for registers, and post up your results?

I Used OBD Scan Tech as it already has the function to scan for registers, and lookrs232 to manually send commands to the ECU.

Scan Tech already has init strings in it, but if you want to manually address the hicas 'FF FF E4' will get it talking, '5A 01 F0' will start it streaming sensor data for register 0x01 and 0x30 will make it stop.

massively interested! i tried to talk to hicas a while back and it wouldn't find it? my old gtst had a second consult port in the boot hanging down under the parcel shelf? couldn't connect here either? seemed to be a useless port? but the gt-r doesn't have a port here and the port near the fuses won't talk to hicas? i have no hicas problems it just interests me. not sure what you mean by manually doing something with ff ff e4? can you explain this?

Second port in the boot is most likely an addition, you can talk to hicas from the port near the fuse box but the amount of information that can be pulled from it i don't know. Should atleast be some active tests that can be run and diagnostics.

It seems software currently available was made on 300zx which has a few small differences to the way skylines present the data, therefore you need to manually speak with the computer in question, ff ff e4 is the init string for hicas, this will cause the hicas computer to listen and respond to the following requests. You can use look rs232 for this.

These 2 documents have what you need to know to get started.
