Disabling Air Suspension
WARNING: Before commencing work which requires access to the underside or wheel arches of the vehicle, the suspension must be allowed to relevel. Relevelling is achieved by opening and closing of any of the side doors, while all other doors and tail gate remain closed, and the ignition off.
EAS (Electronic Air Suspension)must be set in 'high-lock' using Testbook scan tool, or equivalent during any work which does not require chassis to axle displacement. This will hold the suspension in extended profile position, until reset by Testbook.
