Electrics
The EAS like any other system in the vehicle expects and depends on all the electrics to be in good working order. I know that some people who are familiar with previous Lucas vehicles will now be laughing.

It is very important that wiring and fuse systems be inspected for corrosion or physical damage. Some of the most common areas that need inspection are the engine compartment fuse box, the EAS computer compartment and the OBDII port.

The engine compartment fuse box suffers from exposure to engine heat and engine coolant. These are a very common failure item and can be replaced easily for about 150 USD.

The EAS computer is located under the LH seat. Typical inspection includes examination of all wiring harnesses. Make sure that the EAS Delay relay is functioning and that the wiring loom is not damaged. Also inspect the EAS computer C117 connector and ensure that the wiring is not damaged in any way.

The OBDII connector is located in the underside of the RH foot well. It is recomended that the RH footwell pannel be dropped and the backside of the OBDII connector be examined. For example, coolant leaks from the heater core can cause damage to the OBDII connector.

Burnt out fuses are also fairly common. Inspect for any burned out fuses. Specifically, check FUSE 44, FUSE 24 and FUSE 33.

Other Electrical failures include the EAS Heights Sensors and the EAS Driver Pack. The EAS Height sensors rarely fail but when they do, will result in very specific EAS FAult messages. The EAS Fault messages associated with the EAS Height sensors, are the only fault messages that can be taken as truth. When an EAS Height Sensor fault is recorded, it is useful to inspect and clean the wiring harness for that specific height sensor. If the fault returns, then replacement of that specific sensor could be necessary.

Failures of the EAS Driver Pack can exhibit some very strange suspension behaviors and random EAS Fault messages. The EAS Driver pack is located under the EAS Compressor and is attached to the EAS Valve block. The EAS Driver pack is responsible for converting the low current EAS computer logic signals to a high current pulse modulated signal that directly drives the EAS valves. Failures of the EAS Driver pack can result in erratic EAS valve behavior and random height adjustments. The vehicle might suddenly change in height without warning. Another symptom is a reoccuring Pressure switch failure when the switch checks out ok. The EAS Driver pack is not repairable.
