Diags On Hicas - Classic

[vape]

Hey guys,

Ripper search function. Hicas results in nothing too helpful once you have the fault code.

Did the diag and got code 21. Vehicle Speed Sensor Not Present. Np, check the computer at the back, reseat all the cabling to the unit - did seem loose.

Did the diag again and got 12 AND 21.

12 being Hica Power Supply not present.

My goodness. Can anyone tell me what to actually look at in regards to both these errors?

All stock standard steering wheel, no aftermarket stuff. Series 2 R33

AFAIK still got the 180km/h speed limit. Have checked the ECU and the cabling seem fine.

Hicas light always comes on after going above 20 and turning any direction. If I manage to make it to a long straight, the light does not come on even above 80km/h unless I change lane...

/sigh. not sure what to do about this, maybe I will pull apart the cluster and check the tracks on the back of the speedo. I have installed the aftermarket white dials. But was fine after that... but ya never know, it may have come loose or something over time.

Any help appreciated guys!!
