    Special Service Campaign Letter JSD

    Subject: Special Service Campaign JSD – Remedy Notice
    2014 – 2017 Model Year Toyota Corolla
    2017 Model Year Toyota Corolla iM
    2016 Model Year Scion iM
    Continuously Variable Transaxle (CVT) Software Update

    Background:
    Toyota previously announced Special Service Campaign J0D, which involved performing a software update to the CVT control software to address the condition described below. Following the completion of the software update in Special Service Campaign J0D, Toyota dealers received reports from some customers stating that the vehicle experienced harsh shifting and/or abnormal engine RPM between shifts.

    These issues occurred close to the completion date of the campaign and/or within relatively low mileage from the completion of the campaign remedy, prompting Toyota to suspend Special Service Campaign J0D.

    Toyota has now identified the cause of these issues and has developed a new remedy. Special Service Campaign JSD, which replaces Special Service Campaign J0D, applies this new remedy. Owners of all vehicles previously involved in Special Service Campaign J0D, including those who have previously completed Special Service Campaign J0D, are requested to visit an authorized Toyota dealer to have Special Service Campaign JSD performed.

    Condition:
    An Electronic Control Unit (ECU) in the subject vehicles has improper programming that could lead a component inthe Continuously Variable Transmission (CVT) to unnecessarily cycle and experience abnormal wear. If this component becomes damaged, the Malfunction Indicator Lamp (MIL) may illuminate in the instrument cluster and the vehicle could experience a reduction of speed. After reaching a pre-determined gear ratio, the vehicle can be operated up to approximately 37 mph.

    Remedy:
    Any authorized Toyota dealer will inspect the CVT control software and, if necessary, perform an update for that software at NO CHARGE. After inspecting the software and, if necessary, performing the software update, the CVT solenoid valve controlling the gear ratio in the CVT will be inspected* and, if necessary, the CVT valve body assembly will be replaced at NO CHARGE. A portion of the CVT solenoid valve inspection process requires the dealer technician to test drive the vehicle for a certain distance and at certain speeds.

    In the unlikely event that the vehicle is exhibiting the condition (i.e., DTC P2820 is present) before receiving this remedy, any authorized Toyota dealer will replace the CVT assembly at NO CHARGE.

    NOTE: Toyota expects a majority of vehicles WILL NOT require CVT valve body assembly replacement. If parts are not immediately available to replace the CVT valve body assembly on the customer’s vehicle, the customer should be offered a loaner vehicle until parts become available, if possible. Damage to the vehicle’s transmission could occur if the vehicle is driven with the updated software prior to replacing the valve body assembly.

    *: Some vehicles may be exhibiting certain powertrain malfunctions unrelated to the condition covered by this Special Service Campaign, that may interfere with the dealer’s ability to perform the solenoid valve inspection. These powertrain malfunctions MUST be diagnosed and repaired prior to performing this Special Service Campaign (DO NOT perform CVT software update or the CVT solenoid valve inspection until these malfunctions are diagnosed and, if necessary, repaired). Resolution of existing powertrain malfunctions are not covered as part of this Special Service Campaign and should be diagnosed and repaired under warranty if still covered. If the vehicle is not covered by warranty, the customer is responsible for the cost of diagnosis and repair.

    Covered Vehicles:
    There are approximately 1,300,800 vehicles involved in this Special Service Campaign. Approximately 17,800 vehicles involved in this Special Service Campaign were distributed to Puerto Rico.

    Owner Letter Mailing Date:
    Toyota will begin to notify owners in early August 2018. Owners of all vehicles, including those who have previously completed Special Service Campaign J0D will be notified.

    For Valve body assembly replacement required:
    If parts are not immediately available to replace the CVT valve body assembly on the customer’s vehicle, the
    customer should be offered a loaner vehicle until parts become available, if possible. Damage to the vehicle’s
    transmission could occur if the vehicle is driven with the updated software prior to replacing the valve body
    assembly.


    Customers with additional questions or concerns are asked to please contact the Toyota Customer Experience Center (1-888-270-9371) - Monday through Friday, 7:00 am to 7:00 pm, Saturday 7:00 am to 4:30 pm Central Time.


    Frequently Asked Questions

    What is the condition?
    An Electronic Control Unit (ECU) in the subject vehicles has improper programming that could lead a
    component in the Continuously Variable Transmission (CVT) to unnecessarily cycle and experience abnormal wear. If this component becomes damaged, the Malfunction Indicator Lamp (MIL) may illuminate in the instrument cluster and the vehicle could experience a reduction of speed. After reaching a pre-determined gear ratio, the vehicle can be operated up to approximately 37 mph.

    Are there any symptoms that this condition exists?
    If the condition exists, the malfunction indicator lamp, shown below, may illuminate in the instrument cluster and the vehicle could experience a reduction of speed. After reaching a pre-determined gear ratio, the vehicle can be operated up to approximately 37 mph.

    What is Toyota going to do?
    Any authorized Toyota dealer will inspect the CVT control software and, if necessary, perform an update for that software at NO CHARGE.

    After inspecting the software and, if necessary, performing the software update, the CVT solenoid valve controlling the gear ratio in the CVT will be inspected* and, if necessary, the CVT valve body assembly will be replaced at NO CHARGE. A portion of the CVT solenoid valve inspection process requires the dealer technician to test drive the vehicle for a certain distance and at certain speeds.

    In the unlikely event that the vehicle is exhibiting the condition (i.e., DTC P2820 is present) before receiving
    this remedy, any authorized Toyota dealer will replace the CVT assembly at NO CHARGE.

    Is Special Service Campaign JSD related to Toyota’s previous Special Service Campaign J0D?
    Toyota previously announced Special Service Campaign J0D which involved performing a software update to
    the CVT control software to address the condition in Q1, above.

    Following the completion of the software update in Special Service Campaign J0D, Toyota dealers received reports from some customers stating that the vehicle experienced harsh shifting and/or abnormal engine RPM between shifts. These issues occurred close to the completion date of the campaign and/or within relatively low mileage from the completion of the campaign remedy, prompting Toyota to suspend Special Service Campaign J0D.

    Toyota has now identified the cause of these issues and has developed a new remedy. Special Service Campaign JSD, which replaces Special Service Campaign J0D, applies this new remedy. Owners of all vehicles previously involved in Special Service Campaign J0D, including those who have previously completed Special Service Campaign J0D, are requested to visit an authorized Toyota dealer to have Special Service Campaign JSD performed.

    If I already had J0D performed on my vehicle, why is it necessary for my vehicle to have this Special Service Campaign performed?
    The remedy in this Special Service Campaign (JSD) is an updated version of previous Special
    Service Campaign J0D and involves an additional inspection step and, if necessary, an additional
    repair. Even if you already had Special Service Campaign J0D completed on your vehicle, it is
    necessary to have this Special Service Campaign (JSD) completed as well.

    How long will the repair take?
    Inspecting the software, performing the software update if necessary, and performing the CVT solenoid valve
    inspection will take approximately one hour.

    In limited cases, should the results of the CVT solenoid valve inspection determine that the CVT valve body assembly needs to be replaced, the repair will take an additional three and one half hours.

    In the unlikely event that your vehicle has experienced the condition before receiving this repair and requires
    replacement of the CVT assembly, the total repair time will be seven hours for Toyota Corolla vehicles and approximately nine hours for Toyota Corolla iM and Scion iM vehicles.

    Note: Your dealer may provide you with a loaner vehicle depending on which repair mentioned above is
    necessary for your vehicle.


    What if I have additional questions or concerns?
    If you have additional questions or concerns, please contact the Toyota Customer Experience Center at 1888-270-9371 Monday through Friday, 7:00 am to 7:00 pm, Saturday 7:00 am to 4:30 pm Central Time.

    In case anyone is interested, this is what a bad waveform from the JSD Test Drive looks like. In this case a new valve body is needed...

    Can someone explain what's happening here? Will this solve the very high RPM issues when cresting a hill with adaptive cruise on?

    Yes, I knew that but was more interested in just adding to the discussion. I went back and looked at it with the correct scale. Thanks for adding a correct/good looking one.

    Will I notice anything different in my mpg after the update. I'm not a tree hugger but I easily get 39.6 mpg all week long.

    I'm thinking about purchasing a 2015 Toyota Corolla, until we saw this recall. Should I take a chance to buy it?

    I think the Corolla has three option for transmissions, the CVT, a 4 Speed Automatic and a Manual. Just avoid the CVT IMHO and you should be fine.
