ADJUSTMENT PROCEDURES (BLACKWOOD) 

Inflation & Deflation Of Air Suspension System 

Turn the air suspension switch on. The air suspension switch and bracket is mounted in the right side kick 
panel. Connect the scan tool to the Data Link Connector (DLC) and follow the directions. Select Air Suspension 
Module under Active Command Mode. VENT REAR to deflate the rear down. LIFT REAR to inflate the rear 
up. 

Initialize System - Clear B2140 DTC 

1. Turn the ignition key OFF and turn it back to RUN. Exit the vehicle, close all doors and allow the system 

to vent the vehicle down to kneel height (approximately 30 seconds). Connect the scan tool to the Data 
Link Connector (DLC) and follow the directions. Select Air Suspension Module. 

2. Select the "Save Calibration Values (Store Ride Height)" scan tool command to calibrate the air 

suspension module. Trigger through the warning message(s) and save "initialization" (trigger from OFF 
to ON).  

Rear Ride Height Mechanical Resetting 

1. Turn the ignition key ON. Connect the scan tool to the Data Link Connector (DLC) and follow the 

directions. Select Air Suspension Module.  

2. Measure vehicle rear height (driver side) from the bottom of the jounce bumper metal housing to the 

jounce pad on the rear axle. See Fig. 8 .  

3. Using scan tool, adjust rear height to 3.6" (92 mm) by moving the rear of the vehicle down using the rear 

vent active command or by moving the rear of the vehicle up rear lift in rear height sensor PID.  

4. Loosen the ball stud nut on the rear air suspension height sensor-to-axle bracket and adjust it by moving it 

with the air suspension height sensor up or down until the voltage is 2.74-2.78 volt. See Fig. 13 . Tighten 
the ball stud nut to specification. See TORQUE SPECIFICATIONS .  

Rear Ride Height Electronic Resetting 

WARNING:

Do not remove an air spring under any circumstances when there is 
pressure in the air spring. Do not remove any components supporting an 
air spring without either exhausting the air or providing support for the air 
spring to prevent vehicle damage or personal injury. Disconnecting an air 
line that is connected to the air compressor can cause personal injury or 
damage to components as high pressure air is vented uncontrolled.

NOTE:

Do not save rear ride heights. The air suspension module has 
precalibrated values already stored. Refer to Rear Ride Height Mechanical 
Resetting.

1. Connect the scan tool to the Data Link Connector (DLC) and follow the directions. Select Air Suspension 

Module. Select the active commands menu "Save Calibration (Store Ride Height)." Trigger through the 
warning message. Monitor the rear height sensor PID. 

2. Select REAR. Disconnect the rear height sensor link from the lower bracket ball stud. See Fig. 13 . 

Slowly raise and lower the height sensor arm until the sensor voltage is 2.74-2.78 volts.  

3. Press the trigger to save ride height settings (turn from OFF to ON); this will calibrate the air suspension 

control module. Carry out the Rear Ride Height Mechanical Resetting. If the rear height mechanical 
resetting has been performed, clear DTCs and run On-Demand Self-Test.

CAMBER & CASTER ADJUSTMENT 

Blackwood & F150 Pickup (2WD) 

1. If alignment plates have not been removed from upper control arms, remove upper control arm nuts and 

plates. See Fig. 14 . Install washers and nuts. See Fig. 15 . If alignment plates have already been 
removed, go to next step. 

2. Loosen the nuts to a point where the upper suspension arm joints are snug. To increase caster, move the 

front of the upper control arm outboard and move the rear of the upper control arm inboard. To increase 
camber, move the upper control arm outboard equally. See Fig. 16 .  

3. To decrease caster, move the front of the upper control arm inboard and move the rear of the upper 

control arm outboard. To decrease camber, move the upper control arm inboard equally. 

4. Set the caster and camber to specifications. See WHEEL ALIGNMENT SPECIFICATIONS .  

5. If a caster increase of 1.2 degrees is required, move the front of the upper control arm outboard by 3 

notches and move the rear of the upper control arm inboard by 3 notches. Tighten the nuts to 
specification. See TORQUE SPECIFICATIONS . 

NOTE:

A pry bar can be used between the upper control arm and the frame 
pocket to aid in moving the arm.

NOTE:

Each increment of the notches on the frame pocket represents 0.4 degree.
