Red blinking light under dash

ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

ANSWER : Hi there. If you click this link, you should be directed to a Nissan site that explains what each warning light looks like and means; so you can match the one on your dash to the ones on this list. If you can’t find the specific light, look in your owner manual inside the glove box under the warning light section. You could also have a professional mechanic come to your location and complete a warning light inspection, to determine if there is a problem that needs to be resolved.

ANSWER : Hi there. Sure would appear a lot is going on electrically all at once. This could be, a problem in the PDC (power distribution center). The PDC is typically located under the hood and contains numerous fuses and relays. I don’t believe any one fuse will resolve all of the electrical issues. There is a possibility, it is not a power supply issue. It may be, the result of a poor electrical ground common to the inoperative components. Proper circuit testing should be performed. This would confirm the cause of multiple electrical failures. I recommend having your vehicle’s electrical problems be diagnosed and repaired by a certified technician, such as one from YourMechanic.

ANSWER : Hi there. Check the wiring on the vehicle to the tail and brake lights. There is a cross short that is causing the lights to blow the fuses and make the tail lights brighter than normal. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

ANSWER : This is likely a brake light switch problem. I would suggest testing the brake light switch which should be located down by the brake pedal. This may also be a computer problem as well as indicated by the other lights on in the dash. I would recommend having an expert from YourMechanic come to your home to possibly replace the brake light switch and diagnose with a scanning tool which will download useful data from the truck’s computer indicating what specifically the problem may be.

ANSWER : Hi there. The Downhill Brake Control (DBC) light is on for either the system is active by having pushed the on button or the controller under the dash is malfunctioning. First look for the button that turns on the downhill brake controller and see if you can turn it off. If you cannot find the button, then turn the key off and back on and the light should go out. If the light is staying on, then I recommend replacing the downhill brake controller under the dash. If you need further assistance with your downhill brake control light on, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : If a faulty component is still in place, the fault codes will return almost immediately after clearing them. ABS, ESP, and traction control systems all rely on input from wheel speed sensors to determine as the name implies, the speed of each wheel. When a wheel, or wheels are spinning faster than others due to wheel slip or the vehicle is sliding, the ABS and ESP systems can reduce throttle input as well as apply braking to an individual wheel or all of them if needed. With a wheel speed sensor fault code stored, these systems cannot determine the rate that all 4 wheels are spinning and sets a fault. That is why the abs/esp light is on. The system should be scanned by a certified technician and the wheel speed sensor replaced if found to be the cause. The warning lights will stay on and these systems will not function as designed until the fault is corrected. These lights do not come on to indicate a need for routine service. Rather they only come on when a component in the system is at fault.
