System Precautions: Notes
- DO NOT unplug or plug in CAB connector with ignition on. Before bleeding brake system or before disconnecting any hydraulic brake component (including brake lines), depressurize system by turning ignition switch to OFF position and depressing brake pedal 40 or more times.
- Unplug CAB and sensor block connectors before using an arc welder on vehicle. When painting vehicle, CAB and sensor block should be insulated or removed before placing vehicle in oven.
- Visually inspect ABS system before performing any test. Ensure hydraulic system, normal brake system, charging system and battery are okay. Low battery voltage can cause faulty reading. If necessary, connect a battery charger and apply slow charge. DO NOT fast charge battery.
- Ensure parking brake switch, all related electrical wiring, electrical connections and electrical grounds appear okay.
