Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Visual Inspection
A careful and thorough visual inspection of components may quickly identify cause of malfunction and eliminate need for diagnostic testing. Perform visual inspection as follows:
1) Completely depress brake pedal 40 times and check brake fluid level. Inspect modulator assembly for leaks and for damaged or unplugged connectors. Inspect all brake fluid lines for leaks or damage. Ensure all ABS relays are properly installed. See Figure .
2) Inspect all 4 wheel speed sensors and their 2-pin connectors for damage or disconnection. Inspect Controller Anti-Lock Brake (CAB) for secure mounting. Check CAB connector for damage or loose connection. CAB is located on top of right front frame rail.
