Does anyone know the test sequence & fault codes for the R33 GT-S HICAS system?
My dash light HICAS indicator lights up occasionally so I presume that suggests that I should check the fault codes.
I know the codes for the 240Z series but not the Skyline.
Does anyone have the information on the R33 codes?
Thanks

Fault codes

Send an email to the skyline librarian Phil (location Manchester - so you get the right one). He should have the codes.

Procedure

1. Switch ingition off, put car into neutral.

2. Start engine

3. Very quickly (within a couple of seconds), turn the steering wheel left and right about 20 degrees from centre five times, and then pump the brakes five times, then press the brake pedal once more - this will enter diagnostic mode.

4. Drive forwards or backwards about 5 metres at a speed less than 5mph, this will enter full diagnostic mode.

5. The HICAS light in the instrument cluster will be flashing quickly (for normal) or will flash a code indicating any problems.
The long flashes are for the first digit
Short flashes are for the second digit.
This will give you the number you need.

Diagnostics will return to normal after five minutes, or any speed over 5mph, or ingnition is turned off.

Simple really;)
