122-K5X7U-052018-05-21. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE). Subject: Transfer case and transfer case control unit (all-wheel drive control unit)
122-L7P4X-032018-03-13. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); POWER TRAIN. The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the respective driving state. Power transmission between the front and rear axle is controlled electronically via the "all-wheel drive servomotor (transfer case)" and themulti-plate clutches integrated in the transfer case. ? On all-wheel drive vehicles, the drive train can become strained at low speeds and when the steering is turned sharply when "Off-roadmode" is activated, depending on design. ? Under extreme conditions, the drive train can also become strained when "Off-roadmode" is deactivated. ? Customers with little experience with all-wheel drive vehicles can interpret this behavior as a fault, which in turn can result in incorrect diagnoses in the workshop. Remedial action: Customer complaint to be checked: ? Rough-running engine or ? thevehicle vibrates or ? theengine jerks under load/during acceleration.
122-E8R2D-052017-09-14. Service bulletin. EQUIPMENT:ELECTRICAL; POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE). Concerns: All-wheel drive control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Due to an error in the current software for the all-wheel drive control unit, there is a possibility that the all-wheel drive control unit will not be initialized at times after switching on the ignition and as a result, the vehicle's CAN system cannot establish communication with the all-wheel drive control unit.
