To determine if your Beck/Arnley 201-1818 Brake Light Switch is faulty, you can perform several checks and tests. Here’s a step-by-step guide to help you diagnose the issue:
1. Check the Brake Lights:- Symptoms: The most obvious sign of a faulty brake light switch is that your brake lights do not illuminate when you press the brake pedal or they stay on constantly even when the pedal is not pressed.
- Test: Have someone observe the brake lights while you press the brake pedal. If the lights do not come on, or if they stay on continuously, the brake light switch may be faulty.
- Symptoms: If the brake light switch is out of alignment or improperly adjusted, it may not activate or deactivate correctly.
- Test: Inspect the position of the brake light switch near the brake pedal. Ensure that the switch is properly mounted and that the pedal engages or disengages the switch as expected when pressed and released.
- Tools Needed: Multimeter (set to measure continuity or resistance).
- Test:
- Disconnect the Switch: Locate the brake light switch near the brake pedal and disconnect the electrical connector.
- Test for Continuity: Use the multimeter to test the switch for continuity.
- With the pedal not pressed (switch in the resting position), there should be no continuity (open circuit).
- With the pedal pressed (switch engaged), there should be continuity (closed circuit).
- Interpret the Results: If the switch does not show the expected continuity readings, it is likely faulty and needs to be replaced.
- Symptoms: Loose, corroded, or damaged wiring can cause the brake light switch to malfunction.
- Test: Check the electrical connector and wires leading to the switch. Look for any signs of corrosion, frayed wires, or loose connections. Repair any issues found and see if this resolves the problem.
- Cruise Control Issues: In some vehicles, the brake light switch is also connected to the cruise control system. If your cruise control is not disengaging when you press the brake pedal, it could be another sign of a faulty brake light switch.
- Gear Shift Problems: On some automatic vehicles, a faulty brake light switch can prevent the gear selector from shifting out of "Park."
- Test: Some brake light switches make a faint clicking sound when activated. Press the brake pedal while listening near the switch. If you don’t hear a click, the switch might be stuck or defective.
If your tests indicate that the brake light switch is not functioning properly, it is likely faulty and should be replaced. Replacing the Beck/Arnley 201-1818 Brake Light Switch is usually straightforward and can restore the proper operation of your brake lights. If you're unsure or uncomfortable with performing these tests, it's best to consult a professional mechanic.
