Unable to run basic settings within the Adaptive suspension control unit (J775)
Transaction No.: 2055693/2
Release date: 03-Jul-2020
Customer statement / workshop findings
Unable to run Basic setting (full process + rebound end stops) after a new adaptive air suspension control unit has been fitted or work has been
conducted on the suspension system which requires the Basic setting (full process + rebound end stops) procedure performing
Technical background
Referring to Figure 1, During the Basic setting (full process + rebound end stops) the routine can stop during the initial part of the procedure, in
particular at the stage shown in Figure 2, which is when the vehicle is raised to allow all four wheels to hang down to their full rebound position
Should this issue be evident and the Basic settings routine does not continue - Refer to the Measure section of this TPI

-
Measure
1) Navigate to address 74
- Select Guided functions
- Select Read measured values (Figure 3)
Figure 3
2) When prompted search for IDE 07151 –
- When IDE 07151 is located - Select - Starting update
- Monitor the measured value results for each level control sensor (Figure 4)
Figure 4
- Compare the sensor measured results in Figure 4 against the correct tolerance bands shown in Figure 5
- Within the example shown, the left hand rear level control sensor is not in tolerance as the value is 72.06%
Figure 5
3) To allow the Basic setting (full process + rebound end stops) to be successfully completed the measured value results must all be within the
tolerance bands shown in Figure 5
•
Manually adjust the out of range level sensor by moving the sensor connecting arm whilst monitoring the values until the value falls within
the specified tolerance band
Referring to Figure 6, The correct tolerance should be achieved by moving the sensor arm ( by hand within the parts natural limits of
movement) in the required direction until the tolerance band is within specification NOTE: The tolerance can be achieved by using the
recommended method
NOTE: For photographic purposes only the left hand rear sensor is shown in Figure 6
Figure 6
DO NOT ATTEMPT TO ADJUST THE TOLERANCE BAND OF THE LEVEL SENSORS BY PRYING,BENDING OR
MANIPULATING THE SENSOR RODS BY THE USE OF FORCE
•
Once the required tolerance band criteria is met carry out the Basic setting (full process + rebound end stops) until completion
