Diagnostic Aids
WARNING: This page is about a different car, the 2003 Suzuki Vitara. However, it is still accessible from the selected car via links, so may be relevant.
Make sure the integrity of the connection between EBCM and BPMV is secure, tight and free from corrosion.
Since solenoids are an integral part of EBCM, any one of the DTC(s) will usually indicate an internal fault to EBCM.
