Use the table below to help determine the cause of a problem. The likely causes of the problem are indicated in descending order. Check each suspected area in order. Repair or replace faulty parts or perform adjustments as necessary.
NOTE:
When replacing the brake actuator assembly, sensor, etc., turn the ignition switch to OFF.
HINT:
- Inspect the fuse and relay before investigating the suspected areas as shown in the table below.
- Inspect each suspected area in order for the corresponding symptom.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
