Suspension Control ( Automatic - Electronic ): Description and Operation

Fig. 39 Fail-Safe Function Operation:

When a malfunction occurs, the fail-safe system activates to illuminate the active suspension warning lamp and to cut off the current to the fail-safe valve and/or regulate the pressure control valve operation. This gradually changes the oil pressure (applied to actuators for the four wheels) to a uniform pressure so the vehicle can continue to be driven safely.
Refer to Fig. 39 for major malfunctions and fail-safe operations.
