Retrieving
and Clearing DTCs on the Lincoln Mark VIII(8)
Using
a Rotunda Super Star II Tester
(Printer
Friendly)
(Available
for loan for American Air Suspension customers)
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.
#3)
Open luggage compartment and ensure air suspension switch is OFF.
#4)
Set Super Star II Tester mode switch to FAST and set selector switch to EEC/MCU.
#5)
Turn Scan Tool power switch on.
#6)
Set HOLD/TEST push button in HOLD position (Button is up)
#7)
Turn ignition switch to OFF, then ON.
#8)
Ensure both doors on vehicle are closed. (the system most likely will not do
ANYTHING while the doors are open)
#9)
Install Super Star II Tester in diagnostic connector
#10)
Press HOLD/TEST button and latch in TEST position (button is down)
Codes for
function tests will be displayed one after the other.
When
the desired test code number appears, release and depress the HOLD/TEST button.
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.
