Cruise control and taillights stay on
My cruise control and taillights stay on.
Experienced mechanics share their insights in answering this question :
The only thing that can cause this is a short switch in the combination switch for the lights. The system would need to be check for shorts. This is not a common problem. I recommend you have a mechanic like one from YourMechanic inspect your vehicle’s lights to determine what repairs are needed.

If your cruise control light remains on even after you turn the system off, you may have a problem with your speed control assembly. This issue is usually due to a malfunctioning fuse or a communication disruption in your vehicle`s computer.
The most common cause your brake lights stay on is because of a faulty brake light switch or sensor. It can also be caused by a faulty brake pedal or a malfunction in the electrical system. If you recently replaced the rear light bulbs when it occurred, you may have installed the wrong light bulbs.
Bad Switch: One common reason for the Parking Brake light to stay on is a failing or failed switch. This can be checked easily by jiggling the handle after it is down. If the light turns off (or turns off and then back on), the switch is the most likely culprit and will need to be replaced.
The most common reasons a Nissan Xterra cruise control isn`t working are failed control module, sensor or switch issues, or throttle actuation problems. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Since your car`s cruise control is part of an electrical system, it needs a fuse to function properly. A short circuit in this system can cause a fuse to blow, which means that the cruise control will suddenly stop working. Fortunately, replacing a blown fuse is a cheap and easy repair for any auto mechanic.
A cruise control deactivation switch is designed to turn off the cruise control in response to the driver applying pressure to the brakes. The switch, which is designed to remain powered regardless of whether the vehicle ignition is on or off, is located in close proximity to the brake fluid reservoir.
The most likely cause for the brake lights staying on is the brake light switch sticking closed. You can disconnect the plug from the brake light switch at the brake light pedal to see if the lights turn off. If they do, you will need a replacement brake light switch.
If you have left car lights on all night, the battery can quickly run down. It does not make much difference whether it is a halogen, LED or xenon lamp. If you leave the light on for too long, the battery will drain and the car will no longer start.
The brake light switch is a small component near the brake pedal responsible for activating your car`s brake lights. How does it work? When you press down on the brake, the brake light switch turns on the brake lights at the rear of your vehicle. Essentially, it lets the driver behind know that you intend to slow down.
Bad Brake Light Switch
If all three car brake lights are out at the same time, it`s unlikely that the trio of bulbs died simultaneously. In this case, it`s more likely a bad brake light switch.
A radar sensor is installed on the car`s front grille, which can sense how close or far away the vehicle in front is. By sensing this distance, the car will “adapt” its cruise control speed to maintain a safe distance from the vehicle ahead.
A blown fuse is the simplest to explain. If the fuse of your cruise control is bad, the cruise control won`t work. If the speed sensor or speedometer isn`t working, the cruise control won`t work either, since this feature is partially responsible for making the cruise control function properly.
Common signs include speed surges and inability to maintain speed on cruise control, as well as general engine performance issues.
Vehicles equipped with ETCS will automatically disable cruise control if there`s a problem with the engine or transmission, so if a check engine light lights up after starting the engine, get the vehicle to a mechanic as soon as possible.
While placing your hand on the servo, have someone turn on the ignition and turn the cruise control switch to the On position. You should hear and feel the solenoids in the servo click. This lets you know the switch is working and that you have power to the servo.
Generally, when a car cruise control malfunctions it simply turns off. The driver then just has to turn off the cruise control button and take control of the car. If the cruise control does not turn off when you apply the brake, manually turn the feature off and drive normally.
Fuses for everything electrical, including your tail lights, are always found in the fuse box. They are usually located under the hood or in the cabin. Fortunately, you can fix this type of problem by replacing the fuse.
Blown Fuse
A car fuse safeguards the tail light and brake light circuit from overcurrent. However, a high electric load on the rear light can cause a blown fuse and the tail light to stop working.
Some newer vehicles` dashboards are constantly backlit. It`s daytime… so, tail lights aren`t needed. In reality, tail lights are an important part of being seen from behind, especially in winter when days are shorter and snow, rain, fog, and all-around dreariness are common 24 hours a day.
Your rear lights are controlled through the same switch that controls the headlights. Power is channeled through a relay to the rear lights, illuminating them when the switch is engaged.
Tail lights are wired to the same switch that turns on the head lights, making them function easily. If you have automatic lights, the tail lights will turn on when your vehicle is on. If you use a switch to turn your vehicle`s lights on, the tail lights will illuminate once your head lights are on.
Safety is critical anytime you are working with bulbs and wires. Start by disconnecting the car battery. This will reduce the risk of shock or electrocution. Once you have done this, you`ll need to access the tail lights through the trunk or rear hatch.
You only need a Brake-Lite Relay if you`re installing a supplemental towed vehicle braking system that pushes or pulls the brake pedal. With the engine off, step on your brakes. If the brake lights do not illuminate, you do not need a Brake-lite Relay.
You can see your brake light switch by looking under the dash, near the top of the brake pedal. The brake light switch is usually attached to a small bracket that holds the switch, activated when the pedal is depressed, in position.

Having intermittent problems with cruise control on my car
ANSWER : Hello. This can be caused by a number of different issues. Most of the time this is caused by a bad brake switch. If the switch is shorting out, then it will cause the computer to think that the brakes are being applied, which turns off the cruise control. If the switch is fine, then it may have a bad speed sensor or the cruise control switch itself is bad.
One of the easiest tests I do is simply have someone drive behind me and see if the brake lights are coming on without touching the pedal. If it is, then you should replace the switch. If not, then further testing of the circuit has to be done. If you need to have this done, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your cruise control problem.

Adding cruise control on a factory non equipped car.
ANSWER : The unfortunate truth is the dealer is correct. What you are doing is in theory feasible but not common at all. I haven’t run across anyone who has done what you are doing and I have often wondered how such an endeavor might work. My point here is, I am not surprised the dealer isn’t sure because it’s likely they have never done this themselves. The dealer doesn’t set up the PCM (Powertrain Control Module) in the cars they sell. The manufacturer does and guessing what happened when a car is being built is not common knowledge.
Anytime you modify any car, there are always details such as this that you will possibly have to address. When you choose to modify a car, you are now the engineer. The simple answer is that I can’t tell you with certainty whether or not the PCM in your car has cruise control capability. The only way to find out is to allow the dealer to check in out. Independent shops might possibly be able to, but the equipment they have is aftermarket and not produced by Mazda. The electronic equipment the dealer has is. The dealer equipment will most likely be able to do what you need.

PO341 code – cruise control kicks off, engine light and vsa lights go on.
ANSWER : There could be an issue with the cruise control switch and the brake switch. The VSA light refers to the brake system and the light maybe coming on for the brake switch not functioning properly causing the cruise control switch to disengage. The code P0341 refers to the camshaft position sensor, which could be coming on for the sensor malfunctioning. If the camshaft position sensor is not reading properly, then the cruise control will disengage as the engine is not in time correctly. If you need further assistance with your cruise control disengaging on its own, then seek out a professional, such as one from Your Mechanic, to help you.

cruise control stopped working
ANSWER : I just reviewed your cruise control system and it shows you have two switches that deactivate the cruise control. The one on the master brake cylinder and the other on the brake lever above the brake pedal. The vehicle may or may not have the one on the master cylinder but all have the one on the brake pedal lever. You will need to check the connector to the one on the brake lever to make sure no wires are broken. To replace the switch, you will need to disconnect the connector and remove the security clip that holds it on and remove and install the new switch. If you need assistance with this, a technician from YourMechanic can come to your home or office to perform a cruise control switch replacement.

ABS and traction control light on dash. cruise control doesn’t work.
ANSWER : You will have to have the ABS system scanned and not just the engine computer scanned. You will have to monitor the wheel sensors if you get no codes, but if the light is on there is a code stored in the ABS module. One of the wheel sensors is failing and will cause all the problems you’ve mentioned.
A scanner that can access the ABS of the car is needed for this diagnosis. I’d suggest getting the vehicle looked at by a qualified technician who can properly diagnose your ABS light and repair the issue as necessary.
