    Honda has released the following TSB for the affected cars. TSB #SP-10-008-00 dated 11-06-2015

    ModelModel CodeModel Year
    Civic 4DFB82012, 2013 & 2014
    Civic 5DFK1,FK2&FK32012, 2013 & 2014
    Civic TourerFK2&FK32014

    Symptom
    1. When driving, the station being listened to will change to a different station with no input from the user and the i-MID RDS information will still display the original station and will not update.
    2. With Regional setting turned off, the customer will experience degraded FM radio reception the further they travel away from the mast their station is being broadcast from.

    Cause
    Both symptoms are caused by an error within the Audio unit software. The internal clock in the audio unit is set to work within a certain period of time, after which some programs stop to work correctly.

    Countermeasure
    The audio unit software has been modified to reset the internal audio unit clock with every ignition cycle which will resolve the two symptoms.

    Diagnosis
    Note: Before diagnosis check if the vehicle has already had an update for Intermittent Audio Backlight Failure, refer to bulletin SP-10-009-00. If the vehicle already had bulletin SP-10-009-00 software applied then the vehicle will not require this update. Do Not continue with this bulletin and conduct WSM troubleshooting instead.Diagnosis for the audio unit changing station with the i-MID displaying the previous station RDS information should be established by information supplied from the customers complaint. Diagnosis for poor radio reception should be carried out to ensure the symptoms the customer reported are related to this issue.

    Care point: You should ensure the Regional setting has not been turned ON as this could cause poor reception when travelling outside the region the audio unit was set up in. The audio unit self diagnostic check should be carried out which can be found in WSM under i-troubleshooting, Audio system self diagnostic function. The procedure for reception level indication mode should be followed. If the results from this test show there is still an issue then this bulletin should not be used and poor FM signal fault diagnosis in WSM should be followed instead.

    Repair Method
    NOTE: It is important that during the software update that the power is not disconnected from the audio unit as this may cause irreparable damage. The vehicle should be connected to an external power supply to avoid this issue.
