HICAS (Хайкас) Диагностика: 1. при выключенном зажигании коробку на Р или в нейтраль
2. завести мотор
3. в течении 10 секунд после включения зажигания повернуть руль на 20, или больше градусов влево-вправо от центра 5 раз или более, нажать на тормоз 5 раз, нажать на тормоз ещё раз, чтобы войти в тестовый режим
4. повернуть руль влево-вправо на 20 градусов или больше
5. Для ручки нажать сцепу, включить передачу и обратно на нейтраль, для автомата нажать тормоз, включить первую, потом обратно Р.
6. Проехать хотябы 3м с минимальной скоростью хотябы 2кмч
7. Хикас начнет моргать

HICAS Diagnostic:

Turbos come standard with High Capacity Actively Controlled Suspension, a fancy way to say 4 wheel steering. There's a visual diagnostic mode to check for problems in the HICAS functions. The 90-93 TTs have hydrolic HICAS running off the power steering pump, where '94+ utilizes electric actuators to handle the rear steering chores. Their codes are a little different, but the procedure is the same. It might required a few tries to make it work. Be persistant!
Procedure:

1. Ignition switch 'off' manual tranny in neutral or A/T in 'P'

2. Start the engine

3. Within 10 seconds after turning the key to 'ON', start the engine, turn steering wheel from left to right 20 degrees from neutral 5 times or more times & pump the brakes 5 times. Then press the brake pedal again to enter the test mode.

4. Turning the steering wheel left or right past 20 degrees from neutral will cause the rear wheels to turn slightly (~1 degree) (1.).

5. Drive the car forward 15 feet under 9mph to enter the full diagnostic mode.

6. The HICAS dash light will flash a code indicating any problems. Long flash is first digit, short flash is 2nd digit.

7. Diagnostic mode is exited when: ignition is turned off, vehicle speed exceeds 9mph, or diagnostic has operated for 5 minutes.
