Please note that Recall Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator. Approximately 6300 vehicles are involved. Order No. P-RC-2020070005 This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data Control, and MBUSA-SLP S424HH001, Control of Quality Records. 2 P-RC-2020070005 Check/test procedure 1. Remove lower center engine compartment lining (AR61.20-P-1105XG). 2. Check part number at top at actuator of differential lock of front axle. No actuator with the item number A 463 906 33 01 may be installed. Perform check using a mirror as shown in (Figure 1). Figure 1 3 P-RC-2020070005 3. Check part number at top at actuator of differential lock of rear axle using a mirror (Figure 2). No actuator with the part number A 463 906 34 01 may be installed. If part number of actuator at rear axle cannot be read off due to undercoat / paint coat or parts sticker is no longer legible, the actuator will be replaced. Figure 2 a. Part number illegible or corresponds to A 463 906 33 01 and/or A 463 906 34 01: Perform work procedure. b. Part number does NOT correspond to A 463 906 33 01 and does NOT correspond to A 463 906 34 01: End measure. The results of this check must be documented in writing on the work order. 4 P-RC-2020070005 Work procedure 1. Replace actuator of differential lock at front axle and/or rear axle. The parking brake on the rear axle must be opened after the vehicle has been lifted. To do this, press the start button twice without actuating the brake pedal (ignition on) – actuate the brake pedal – move selector lever to “N” position (read on display) – open parking brake – switch off ignition. Attention: Now that the vehicle is in permanent “N,” there is a risk of the vehicle rolling away. Only actuators with incorrect or illegible part number will be replaced. For basic data for actuator of front axle, see AR33.40-P-0001XGA. For basic data for actuator of rear axle, see AR35.40-P-0001XGA. New actuator must not be painted.(Figure 3) Observe installation instructions for rear axle actuator. Figure 3 5 P-RC-2020070005 Important: The new rear axle actuator from the replacement parts department is delivered in “lock engaged” condition. (Visible by the position of the bolt on the actuator)(figure 6) To install the new actuator, the lock in the rear axle must be engaged manually. With the actuator removed, the slider in the axle tube for actuating the lock must be moved in the direction of the axle centerpiece (figure 5), e.g. with a Torx wrench. One of the rear wheels must be turned at the same time. The bolt of the actuator is always installed in the large opening.(figure 4 and 5) Figure 4 (lock NOT engaged: slider to wheel) Figure 1 (lock engaged: slider to axle centerpiece) 6 P-RC-2020070005 Figure 6 (installation position of rear axle actuator with new part) The differential lock opens automatically during the first ignition sequence. 2. Check differential locks of front and rear axle for proper operation. For this purpose, start the engine – engage low range “N” position – actuate transfer case differential lock switch/rear axle differential lock switch/front axle differential lock switch – drive in gentle figure 8 lines at walking pace in an open area until the red feedback of all three locks appears on operating switch (figure 7) – deactivate locks and low range.

The electrical contact of a specific resistor might be impaired due to sulfur fumes originating from the axle oil. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If the resistor is impaired, the electrical currents calculated with this resistor would have a higher value than in fact exists. In consequence, the communication between the control unit and the locking actuator will be shut down. In this case, the differential locking status could not be reliably determined. According to the specified system strategy for locked differentials, both ESP and ABS systems would be deactivated. This could increase the risk of a crash under certain operating conditions. Description of the Cause : Due to a development deviation at a supplier, for a certain batch of electrical resistors the requirements for chemical resistance might not have been taken into account. Identification of Any Warning that can Occur : The customer will be made aware of the issue by an ABS and ESP message in the instrument cluster. Involved Components : Component Name 1 : NR Component Description : NR Component Part Number : NR Supplier Identification : Component Manufacturer Name : Tollo Linear AB Address : Estrids väg 10 Kristianstad FOREIGN STATES 29109 Country : Sweden Chronology : Part 573 Safety Recall Report 20V-090 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 In July 2018, MBAG launched an initial investigation based on isolated cases of field reports from various markets where customers reported receiving an in-vehicle message about a malfunction with the locking mechanism of the rear differential. MBAG requested that parts from affected vehicles be returned for further analysis. MBAG’s analysis continued through the end of 2018 and into 2019 and involved an analysis of the performance of a variety of different components of the differential locking systems. In April 2019, MBAG’s analysis began to focus in on the operation of a specific resistor within the differential system. The analysis eventually found that sulfur from the axle oil was impacting the performance of an electrical contact in the resistor and MBAG began to analyze the effects of an affected resistor. It was found that if a resistor were impacted, communication between the differential control unit and the differential locking actuator would be interrupted. The differential control unit would interpret the differential as being in a “locked” condition and ABS and ESP functions would be deactivated. The deactivation of these systems is consistent with the strategy for a locked differential and is a protective measure. It was also found that if the condition occurred at low speeds, as was consistent with most reports from the field at the time, the vehicle could be stopped safely and braking performance was not affected. Subsequently, in December 2019, MBAG analyzed the effects of the condition at higher rates of speed. While field data indicates less than 2% of the reports occurred at higher operating conditions, on February 7, 2020, decided to conduct a recall to address the condition. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will check the differential locking modules on the affected vehicles and replace them, if necessary. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since none of the involved vehicles would have been previously subject to the condition described and all remain covered under the new vehicle warranty. How Remedy Component Differs from Recalled Component : Differential locking modules equipped with electrical resistors resistant to sulfur fumes. A4639064602 TS Aktuator VA A4639065502 TS Aktuator HA Identify How/When Recall Condition was Corrected in Production : A change in the development process of our supplier ensures that this issue can no longer occur from October 9, 2019 onwards.

MBAG’s analysis continued through the end of 2018 and into 2019 and involved an analysis of the performance of a variety of different components of the differential locking systems. In April 2019, MBAG’s analysis began to focus in on the operation of a specific resistor within the differential system. The analysis eventually found that sulfur from the axle oil was impacting the performance of an electrical contact in the resistor and MBAG began to analyze the effects of an affected resistor. It was found that if a resistor were impacted, communication between the differential control unit and the differential locking actuator would be interrupted. The differential control unit would interpret the differential as being in a “locked” condition and ABS and ESP functions would be deactivated. The deactivation of these systems is consistent with the strategy for a locked differential and is a protective measure. It was also found that if the condition occurred at low speeds, as was consistent with most reports from the field at the time, the vehicle could be stopped safely and braking performance was not affected. Subsequently, in December 2019, MBAG analyzed the effects of the condition at higher rates of speed. While field data indicates less than 2% of the reports occurred at higher operating conditions, on February 7, 2020, decided to conduct a recall to address the condition. Description of Remedy : Description of Remedy Program : An authorized Mercedes-Benz dealer will check the differential locking modules on the affected vehicles and replace them, if necessary. Pursuant to 49 C.F.R. § 577.11(e), MBUSA does not plan to provide notice about pre-notice reimbursement to owners since none of the involved vehicles would have been previously subject to the condition described and all remain covered under the new vehicle warranty.
