    Description of DTC code C1252 Generic

    The CVRSS Module (Continuously Variable Road Sensing Suspension) estimates the road surface and then sends that data to the EBCM (Electronic Brake Control Module). The CVRSS Module provides a Pulse Width Modulation (PWM) signal to the EBCM via the left and right normal force signal circuits. Each out value is sent twice, where the possible PWM duty cycle values are 20%, 40%, 60%, and 80%, with a valid range of 10-90%. This data is used by the EBCM to ensure better road braking performance.

    When the C1252 OBDII fault code is stored, it means that a problem was detected in the left front normal force, which is not within the values established by the manufacturer.

    Symptoms of fault code C1252 Generic

    Causes of OBD2 C1252 Generic

    The reasons for setting the C1252 OBD2 diagnostic code are:

    • Electronic Brake Control Module wires could be bad.
    • EBCM electrical connections could be damaged.
    • The Electronic Brake Control Module may be defective.

    Possible solutions of the DTC code C1252 Generic

    To troubleshoot the DTC C1252 OBDII code you must do the following:

    • As a first step consult the Technical Service Bulletins.
    • Check the cables related to the EBCM and verify that they do not present common deficiencies due to burns or wear. Repair or replace it as required.
    • Measure circuit voltages associated with the Electronic Brake Control Module and check to see if they are within the manufacturer's specifications. If you discover discrepancies, proceed with the appropriate adjustments.
    • Following the manufacturer's recommendations, verify the integrity of the Electronic Brake Control Module. However, because this diagnosis is complex, we recommend that you visit an advanced service center.
