Check that the vehicle is free of obstructions. Check the height
sensor for correct fitment and torque of fixings. If any height
sensor fixings are slackened or found to be loose, or a height
sensor has been changed, the vehicle ride height must be re-
calibrated. Calibrate the system using the approved diagnostic
system. Refer to the guided diagnostic routine for this code on
the approved diagnostic system. Check for an air spring leak.
Check the air harness for evidence of melting, crushing, kinking
or collapsing. Check the front and rear valve block pipes for
correct routing and installation. Check the reservoir valve block
pipes for correct routing and installation. Refer to the approved
diagnostic system for corner, reservoir and exhaust valve
checks. Check the corner valve for leaks.
