IMPORTANT: It is recommend that the defective components be replaced, and not the complete brake master cylinder assembly.
  1. Most occurrences of this DTC are caused by excessive TCS activation or braking. Review with the customer to verify the conditions under which the DTC set.
    • If vehicle operation caused this DTC to set, clear the DTC.
  2. Test drive the vehicle under normal conditions
    • If the DTC resets under normal driving conditions, replace the EBCM/brake pressure modulator valve (BPMV).
