Hyundai has released Technical Service Bulletin (TSB) 22-01-006H, also known as Service Campaign T7R, to improve the drivability and shift quality of certain 2022 Santa Fe (TMA) and Tucson (NX4A) vehicles. This bulletin outlines the procedure for updating the Engine Control Unit (ECU) and Transmission Control Unit (TCU) software. The goal of this update is to enhance acceleration logic and reduce instances of rough shifts and hesitation during acceleration, directly addressing concerns about 2022 Hyundai Tucson drivability.
Important Warnings
Hyundai has mandated that dealers must perform this Service Campaign (T7R) on all affected vehicles prior to customer retail delivery. This ensures that new vehicles are delivered with the latest software improvements.
Symptoms
Owners of affected 2022 Hyundai Santa Fe and Tucson vehicles may experience the following symptoms:
- General drivability concerns
- Poor shift quality when accelerating
- Rough shifts
- Hesitation during acceleration
These issues are targeted by specific software logic improvements for the ECU and TCU. For the ECU, the update focuses on "ACCELERATION LOGIC IMPROVEMENT (ECU)", identified by GDS Event #771 for Santa Fe (TMA) and #775 for Tucson (NX4A). For the TCU, the update targets "ROUGH SHIFT AND HESITATION IMPROVED LOGIC (TCU)", identified by GDS Event #772 for Santa Fe (TMA) and #776 for Tucson (NX4A).
Repair Procedure Summary
The repair involves updating the ECU and TCU software using Hyundai's Global Diagnostic System (GDS). The update should initially be performed in Auto Mode.
If the ECU or TCU update fails to complete in Auto Mode, a specific recovery procedure must be followed:
- Disconnect both battery cables.
- Touch the disconnected battery cables together for one minute.
- Reconnect the battery cables.
- Attach a battery charger to the vehicle.
- Perform the software update again, this time using Manual Mode.
Technicians should refer to General Instructions TSB 15-GI-001 (GDS Mobile) for detailed guidance. After the TCU update is successfully completed, it is essential to check for any Diagnostic Trouble Codes (DTCs) and erase them from the vehicle's memory. This update is designed to resolve the 2022 Hyundai Tucson drivability issues.
Required Tools or Parts
The primary tool required is the Global Diagnostic System (GDS) for software flashing. A battery charger is also necessary for the manual update procedure. The update involves specific software ROM IDs. The following tables detail the old and new ECU and TCU ROM IDs for the affected models.
