Diagnostic Aids

WARNING: This page is about a different car, the 2004 Suzuki Swift + and 2004 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

Ensure the integrity of the connection between the EBCM and the brake pressure modulator valve (BPMV) is secure, tight and free from corrosion.

Since the solenoid coils are an integral part of the EBCM, any one of the DTCs settings will usually indicate an internal fault to the EBCM.
