System Operational Test

1. Measure distance to floor from center of rear wheel opening.
2. Reset the height sensor time limit accumulators as follows. Failure to perform the following step can result in incorrect diagnosis. Cycle ignition "Off" and "On." Leave ignition "On" during testing.
3. Apply a load of 200 pounds to rear of vehicle.
4. There should be a 7 - 15 second delay on all models before compressor turns on and vehicle starts to rise within 3-4 inch of measurement noted in step 1. Failure of the vehicle to return to within 3-4 inch of unloaded dimension can be caused by unusually heavy loading in the trunk which exceeds the capacity of the system. If this type of loading is encountered, the compressor will run for several minutes and then shut off. The excess load should be removed and the test repeated. Follow procedure under step 2 to ensure resetting the height sensor time limit accumulators.
5. Remove load applied in step 3. There should be a 7 - 15 second delay on all models. Vehicle should lower to within 3-4 inch of measurement taken in step 1 within 31-2 minutes on all models.
6. If system does not operate as described previously, refer to "System Diagnosis."
