Retrieving and Clearing DTCs on the Lincoln Mark VIII(8) Using a Rotunda Super Star II Tester ATTENTION BEFORE TRYING TO RETRIEVE ANY CODES IN THE SYSTEM, YOU MAY WANT TO HAVE THE BATTERY & CHARGING SYSTEM CHECKED. A WEAK BATTERY WILL CAUSE ALL SORTS OF PROBLEMS IN THE AIR SUSPENSION. AUTOZONE AND A FEW OTHER AUTO PARTS STORES WILL USUALLY DO THIS FOR FREE. Function Test Procedure #1) Open hood and locate diagnostic connector on front of RH front shock tower. (this connector is on the pass. side strut tower and may have a black cap reading "SUSP/EVO") #2) Install battery charger to provide power during testing. NOTE: If you have a bad battery (weak cell), you may still experience problems during this test even though you have the battery charger on the vehicle.
#5) Turn Scan Tool power switch on. #6) Set HOLD/TEST push button in HOLD position (Button is up)
#8) Ensure both doors on vehicle are closed. (the system most likely will not do ANYTHING while the doors are open)
#10)
Press HOLD/TEST button and latch in TEST position (button is down)
This is an excellent way to test independant parts of the system and/or perform wiggle tests(this is to power up a part, then "wiggle" the connector in order to find a loose connection and/or bad wire). It is also the easiest way to test a sensor, by listening for the beap. The closer the beeps are to each other, the closer to trim height you will be. if you don't hear a beep, or you heard a beep, then it quits, you know you have a bad sensor. I
