Danger | Risk of death from lowering vehicle when working between wheels and body. Risk of injury from pinching or crushing when working on the air suspension. | Testing and repair work between the wheel and wheel arch or in the wheel well should only be performed if the vehicle is secured using suitable support fixtures to prevent it from lowering. | |
1 | Put the vehicle in a flat and leveled place, if possible on a proper ditch. | Apply parking brake and chock the wheels to prevent that the vehicle moves accidentally. | |
2 | Disconnect the wire harness from connection (4) of the level sensors | Tie the electric harness and protect the connections to prevent the entrance of earth or water. | |
3 | Remove the nuts (13), and loosen the adjustment rods (7) from the bottom supports (12) | We recommend that you keep the original length of the rods, because the adjustment will be carried out afterwards. | |
4 | Remove the flanged nuts and the two fastening bolts (6) of the sensors (1) from the supports | Pay attention in the fixation of the level sensors, because each sensor has 4 holes, two on upper part and two on lower part. The incorrect fixation, alters the height and causes subsequent problems. | |
5 | Remove the sensors (1) complete with the actuation arms (2) and the adjustment rods (7) | The actuation arms (2) are integral parts of the sensors. | |
6 | Remove the adjustment rods (7) from the actuation arms (2) | ||
| Clean | ||
7 | Clean all components of the level adjustment sensor | Clean accurately the components, specially the rods (1), the sliding ball joints (10) on the adapters (9) of the adjustment rods (7), and the ball studs (11). | |
8 | Lubricate the ball joints (10) and the ball studs (11) with specified grease | Remove excess of grease from the ball joints. | |
| Install | ||
9 | Install the adjustment rod (7) in the upper ball stud integrated on the actuation arm (2) of the level sensor | Take care to not damage the articulation or the actuation arm. | |
10 | Install the new sensors (1) together with (2) the supports of the structure, and fasten them at the original position with the two bolts (6) and the respective self-locking nuts | An excessive tightening of bolts and nuts can damage the sensors and cause functioning failures. | |
.ENR electropneumatic suspension level sensor fastening to the upper support of ENR - support on the structure | |||
11 | Connect the electric harness with the electric wiring in the connection (4) of the level sensor | If it is necessary, fasten duly the end of the electric harness with proper clamps. | |
12 | Block the sensor at position 'Zero' | Spin the lever (2) in the sensor until the hole coincides with the center of the two projecting parts. In this position, insert the pin (5) or an adequate punch. | |
Whenever the level sensors of the electropneumatic suspension with ENR system (ECAS) are removed, it will be necessary to carry out a new adjustment of the three heights (H1) on front part and (H2) on rear part | |||
In this position, the sensor is blocked at point “zero” with the actuation arm (2) set on horizontal position. | |||
13 | Adjust the heights of the electropneumatic suspension with ENR system | Calibrate electronic level control (ELC (ENR)) control unit | |
Calibrate electronic level control (ELC (ENR)) control unitVehicle 382.188/189 | |||
In this position are carried out the calibration operations of the diverse heights with the diagnosis equipment. | |||
14 | Fasten the adjustment rods (7) to the lower supports (12) and tighten the new self-locking nuts (13) | .Fastening of the level sensor rod articulation of the ENR electropneumatic suspension on the support | |
15 | After finishing the adjustment of the rods (7) carried out with the diagnosis equipment, check the tightening of the nuts (8) | .Fastening of the level sensor rod articulation of the ENR electropneumatic suspension on the support | |
16 | Seal the adjustment nuts (8) in the adjustment rod (7) | Use thick enamel or an adequate paint. |
