ELECTRIC SUPER HICAS
INSPECTION BEFORE DRIVING
Check fluid leakage from power steering components (gear, pump, piping, etc.), and check whether the
fluid level is within the proper range.
Check whether tire size and inflation pressure are within the specified limits. Check also whether the
steering wheel is a genuine part, and whether a non-genuine control unit is attached.
Check whether wheel alignment is within the specified limits.
Check whether suspension system is modified, and whether the modification, if any, has increased the
vehicle weight.
INSPECTION DURING DRIVING
Check facts about trouble (what, when, where, who, why and how).
Check whether the engine is running in good condition.
System Description
This system contains two functions for SUPER HICAS: self-diagnosis function and fail-safe function.
For self-diagnosis function, refer to "SELF-DIAGNOSIS PROCEDURE on pages ST-7 and
ST-12.
FAIL-SAFE FUNCTION
If the system detects some error, it halts the normal control and enters the fail-safe mode.
In this event, the system notifies the driver of a malfunction by turning ON the HICAS warning lamp.
The fail-safe mode is canceled when ignition switch
is turned OFF. If, however, the fail-safe mode is caused
by a vehicle speed signal error, it is automatically canceled when the signal is restored before the ignition
switch is turned OFF.
HICAS WARNING LAMP
When the system is in normal condition, HICAS warning lamp is turned ON by switching the ignition ON, and
is turned OFF after engine has started.
