Description

Hyundai is conducting a service campaign to enhance the knock sensor software to detect abnormal engine bearing noise before
potentially severe engine damage occurs. If abnormal engine bearing noise is detected, the Malfunction Indicator Lamp (MIL) will blink
continuously, and the vehicle will be placed in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for
diagnosis and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be operated for a limited time in
Engine Protection Mode, but it will accelerate slower and have a reduced maximum speed. Engine RPMs will be limited to approximately
1800-2000 RPM.

Service Action
Reservation – Always check the Vehicle Information Screen in WebDCS for open campaigns and recalls, and
advise the customer on time requirements.
Readiness - Review this announcement and the accompanying FAQs with all Service and Parts staff including
Reservationist/BDC. Also, complete all applicable training, check your reservation capacity settings (you can set separate
capacities for every recall/campaign), confirm email addresses for campaign appointments, and that you have all necessary
tools, campaign parts and shop equipment as needed.
• Recommended Level of Technician Certification and/or Completed Coursework to perform TSB work:

•

o Minimum Certified Level Certification
Be prepared to put customers in an SRC or alternative transportation, if needed.

Reception – Always check the Vehicle Information Screen in WebDCS for open campaigns and recalls, and print a
copy for technicians. Provide SRC, alternative vehicle, shuttle, or rideshare as needed. If a customer has declined
the campaign, note this on the repair order and request the customer’s signature next to the statement.
Repair – Always plug in the GDS before starting the repair. Make sure to complete an MPI on all vehicles and Quality
Control your work.
• Please refer to TSB #21-01-023H-4 for complete service procedures.
• If voltage is below 12 volts as per the GDS warning, then select Back and run the engine at least 15 minutes to reach
an adequate battery state of charge to prevent ECU Update failure. Cycle the ignition OFF/ON before retrying ECU
update again.
• You must initially perform all GDS ECU Updates in Auto Mode.
o If the ECU Update starts but then fails in Auto Mode, perform the update in Manual Mode to recover.
• PLEASE NOTE:
o If the Automatic ECU Upgrade process fails, cycle the ignition key to OFF for at least 30 seconds to reset
the control unit. Then resume programming using the Manual ECU Upgrade processes.
o After the ECU Upgrade process shows 100% complete, cycle the ignition key again to OFF for at least 30
seconds to reset the control unit. This step is important for establishing normal powertrain communication
and to prevent system errors.
• Refer to TSB 15-GI-001 for additional tablet-based Mobile GDS ECU update information.
• Clear DTC(s) present after the ECU update.
• REMINDER Upon Completion of Service Procedures: After the software has updated, check for Diagnostic
Trouble Codes in the ALL menus and erase any DTCs. Reprogram the customer’s radio preset stations, if
necessary.
Return – Review all completed campaigns/recalls and repairs to answer any customer questions. Also, schedule the
customer’s next service.
Reconnect – Follow up for customer satisfaction.
