The Electronic Brake Control Module (EBCM) is sending an abnormally low voltage signal.
- Shorted or open wire in EBCM harness
- Poor electrical connection in EBCM circuit
- Defective EBCM
- Visually inspect all wiring and connectors in EBCM for loose, open or shorted connections
- Test EBCM for resistance and compare readings with manufacturer’s specs. If they are out of range consider replacing
