HICAS Diagnostic Mode

There is a HICAS warning light in the instrument cluster. If it comes, on it is indicative of a

R32: Check the HICAS oil level (power steering reservoir in some models, or a remote
reservoir accessible from the boot)

R32 and R33: Check all HICAS electrical connections, and if the light remains on, follow the
diagnostic below.

Note that having an aftermarket steering wheel fitted without the appropriate HICAS boss
adaptor can also cause the HICAS system to show a fault. Advanced Imports in Auckland
stock the HICAS Boss adaptor kits.

- Switch ignition off, transmission in neutral or auto in Park.
- Start engine
- Very quickly (with 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.
- Drive forwards or backwards about 5 metres at a speed less than 10km/hr, this will
enter full diagnostic mode.
- The HICAS light in the instrument cluster will be flashing quickly (for normal) or will
flash a code indicating any problems.
- Long flash = first digit, short flash = second digit.
- Diagnostics will return to normal after five minutes, or any speed over 10km/hr,
or ignition is turned off.
