Service
Review TSB 2033589. If TSB 2033589 does not apply, or if it has already been performed on this
vehicle, continue to step 2.
For Scenario A:
Replace the level sensor that has lowest DTC.
For example: if both DTC 774 (Left rear level control system sensor - G76: short circuit) and DTC 1769
(Sensor for vehicle leveling right front – G289: short circuit) are stored, replace sensor G76 because its
DTC is the lower of the two.
For Scenario B:
Replace the affected level sensor.
