System Operational Tests: Notes

NOTE: Cycle system by turning ignition switch "OFF" and "ON". On Eldorado, Riviera and Toronado, transmission selector must be in "REVERSE". This procedure will reset the height sensor timer circuit.
  1. Measure vehicle riding height and start engine momentarily. Leave ignition switch "ON".
  2. Apply approximately 250-300 lbs. load to rear of vehicle.
    • There should be 8-14 seconds delay before compressor turns on and vehicle begins to raise.
    • Vehicle should raise to within 3/4" of riding height by the time compressor shuts off.
    NOTE: Be sure applied load has not exceeded system capacity. This could cause failure of vehicle to rise to 3/4" of unloaded height.
  3. After removing load, there should be 8-14 seconds delay before vehicle begins to lower.
  4. Vehicle should be within 3/4" of the unloaded height in 3 1/2 minutes.
