Self-Diagnostic System: Notes
When vehicle is started, ABS system runs a self check on the following:
- Voltage (9-19 volts).
- Pump (operation, voltage supply and voltage feedback).
- System (external RFI, system open or short, solenoid valve and valve driver).
- Internal circuits.
- Communication circuits.
Any faults will set a code, ABS warning light will illuminate and ABS will not operate.
