Anyone know where is the Super HICAS Control unit in 1993 RHD 2+2 Z32? Only 2seater HICAS control unit could be find on service manual. I just got the HICAS light staying on with the code 13, 21, 22, 23, 31... basically all sensors are not present to HICAS control unit. I think I've got some plugs problem, because I checked the ECU code is 55 (no problem), which mean at least it got Vehicle speed signal to ECU...
I find that sometime it will stay on all the way until tune off the engine. but sometime it won't light on at start and everything work fine.... anyone know what is that problem ?
