System Service

CAUTION: Before performing any service procedure on the anti-lock brake system, the following precautions should be observed:

1. The control module must be disconnected before performing any electric welding.
2. Use caution not to subject control module to a maximum heat of 185°F for longer than 2 hours.
3. After replacement of any ABS component, the entire system should be tested.
4. Ensure inlet and outlet brake lines are properly routed.
5. Do not use a fast charger for starting engine.
6. Never disconnect battery from vehicle when engine is running.
7. Do not connect or disconnect control module electrical connector with ignition switch in On position. Ensure all harness connectors are securely connected.
8. No screws on the modulator valve should be loosened. If screws are loosened, it is no longer possible to get brake circuit leak-tight.
9. When replacing modulator valve, it should be removed through access panel in rear storage compartment. Ensure vehicle interior and exterior are protected to avoid damage from brake fluid spillage. Do not remove bottom of storage compartment to replace modulator valve.
10. Ensure rear storage compartment is wiped clean after replacing modulator valve.
11. Do not support suspension components by wheel speed sensor wires.
12. Wheel speed sensors are a tight fit into knuckle, but should be pushed in by hand. Do not hammer sensors into position.
13. Each replacement wheel speed sensor is identified with a white tag, located approximately 3/4 inch from neck of sensor, labeled L (left), or R (right).
14. Tire and wheel assemblies should be removed when replacing wheel speed sensors.
15. Ensure proper routing, position, mounting and location of all components, including wiring, connectors, clips, bracket and brake pipes, when performing ABS/ASR service.
16. Note: Do not use silicone type brake fluid.
