Inversion Relay Valve Part No. : 9178990020, RKN28032 Size : NR Function : See Description
Descriptive Information : ZF makes this submission based on the recall of vehicles by Spartan Fire, LLC (23V-631) and DTNA (24V-013) that incorporate certain Haldex inversion relay valves within the park brake actuation air brake system, supplied by ZF. As reported by Spartan Fire and DTNA, air brake systems built with these Haldex inversion valves may cause the park brake engagement on certain vehicles to be intermittently delayed.
The total number of potentially affected parts specified herein is the number of parts ZF supplied to the recalling vehicle manufacturers that were manufactured within the identified suspect production dates, as well as parts sold by ZF on the aftermarket. The relevant ZF part number is 9718990020, supplied to Spartan Fire and DTNA, and RKN28032, supplied to the aftermarket. The information provided herein is based on information available to ZF at the time of submission and may not include all information available to the recalling vehicle manufacturers. Production Dates : JUN 01, 2022 – SEP 11, 2023 Part 573 Safety Recall Report 24E-011 Page 2 Description of Noncompliance : Description of the Noncompliance : As described by Spartan Fire and DTNA, if this condition exists, an inversion relay valve may cause the park brake engagement to be intermittently delayed, which may prevent the park brake from engaging within 3 seconds of application. Park brakes that fail to engage within 3 seconds of application may fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 121, Air Brake Systems. FMVSS 1 : 121 – Air brake systems FMVSS 2 : NR
Description of the Safety Risk : As reported by Spartan Fire and DTNA, an intermittent delay in park brake
engagement could increase the risk of a vehicle rollaway.
Description of the Cause : Based on ZF’s investigation, an issue was identified with the piston concentricity in the Haldex inversion relay valves Identification of Any Warning
that can Occur : As described by Spartan Fire and DTNA, in the event of a delayed valve, the vehicle operator may notice the lack of a normal park brake exhaust noise. Involved Components : Component Name : Inversion Relay Valve Component Description : NR

See attached chronology The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 24E-011 Page 3 Description of Remedy :
Description of Remedy Program : ZF is providing this information report in accordance with 49 CFR 573.3
(f). ZF refers to the vehicle manufacturers’ respective filings for details about their respective remedy programs. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : FMVSS 121 is a vehicle-level standard that ZF does not certify to. Nevertheless, in light of the decisions made by Spartan Fire and DTNA to conduct non-compliance recalls, and because same or similar parts were sold by ZF in the aftermarket, ZF will conduct a voluntary recall campaign under these circumstances that will cover replacement parts that ZF supplied into the replacement market through independent distributors.
As described by Spartan Fire, the inversion relay valves that will be used to replace the recalled components have either been through the supplier’s inspection process to identify the potential defect, or an improved piston machining process was utilized in their manufacture. Remedy inversion relay valves also exhibit a specific marking on the data tag.
Haldex improved clamping on parts to avoid movement during the piston machining process. Haldex has also developed and implemented an offline inspection process. Recall Schedule :
Description of Recall Schedule : ZF refers to the vehicle manufacturers’ non-compliance reports for
details regarding their respective recall notification schedules. ZF will notify its distributor/dealer customers of ZF’s decision to conduct a voluntary recall campaign for replacement parts in accordance with the Planned Dealer Notification dates listed herein. ZF will work with those customers to identify and notify owners of replacement parts.
