DESCRIPTION
Electronically Controlled Suspension (ECS) is designed to improve vehicle ride characteristics while automatically compensating for driving conditions. System controls shock absorber damping through electronic valve control of shock absorbers.
Using ECS switch on dash, driver can manually select damping characteristics for regular driving by selecting either TOUR mode (soft damping) or SPORT mode (hard damping). Shock absorber damping is automatically firmed up under braking (anti-dive function), quick acceleration (anti-squat function) or hard cornering (anti-roll function).
ECS control unit is equipped with self-diagnostic function which monitors several circuits and alerts driver when a malfunction is detected.
| WARNING | Stealth and 3000GT are equipped with a Supplemental Restraint System (SRS) that includes an air bag, located in steering column. Use caution when working around steering column. Ensure battery is disconnected before attempting any repair. DO NOT apply electrical power to any component on steering column without disconnecting air bag module (air bag could deploy). |
OPERATION
ECS control unit uses inputs from ECS switch, "G" sensor, shock absorber actuator position detection switches, vehicle speed sensor, throttle position sensor, stoplight switch and steering wheel angular velocity sensor. The control unit uses these inputs to determine proper valving for the specific ride characteristics. Valving inside strut housing governs strut dampening characteristics.
ECS switch is used to manually select basic ride characteristics. The "G" sensor detects pitching, bouncing and rough road. Steering wheel angular velocity sensor, located in steering column, detects how fast the steering wheel is being turned.
Air Bag System Operation Check
Turn ignition switch to ON or START position. SRS warning light on instrument panel should illuminate for approximately 7 seconds then turn off. This indicates SRS is functioning properly. If any of the following conditions exist, SRS is malfunctioning and needs repair.
- SRS warning light does not illuminate as described.
- SRS warning light stays on for more than 7 seconds.
- SRS warning light illuminates while driving.
If SRS warning light does not illuminate as described, SRS system is malfunctioning.
