On-Vehicle Inspection
- INSPECT STOP LIGHT CONTROL RELAY (BRK-LP)
- Remove the stop light control BRK-LP relay.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance

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.
