The Service 4WD Light on your Ram 2500 indicates a problem with the four-wheel drive system. The light may come on due to a problem with the transfer case, the vacuum system, or the differential. If the light is on, it’s important to diagnose and fix the underlying issue. To clear the Service 4WD Light on your Ram 2500, follow these steps:
1. Check Your Transfer Case Fluid – The transfer case is an important component of the four-wheel drive system, and if the fluid is low, it can cause the Service 4WD Light to come on. To check the fluid level, you’ll need to locate the transfer case fill plug and then remove it. Use a dipstick to check the fluid level, and if it’s low, you’ll need to add more fluid. Make sure to use the correct type of fluid for your transfer case.
2. Check the Vacuum Lines – The vacuum system is responsible for controlling the four-wheel drive system, and if there are any leaks in the lines, it can cause the Service 4WD Light to come on. To check for leaks, start by locating the vacuum lines and then inspect them for any cracks or leaks. If you find any, you’ll need to replace the damaged lines.
3. Check the Differential – The differential is an important component of the four-wheel drive system, and if there is any wear or damage, it can cause the Service 4WD Light to come on. To check the differential, you’ll need to jack up the vehicle and remove the differential cover. Once the cover is off, inspect the differential for wear or damage, and if you find any, you’ll need to replace the differential.
4. Reset the Light – After you’ve diagnosed and fixed the underlying issue, you can reset the Service 4WD Light. To do this, start the engine and then turn the key to the “Off” position. Now press and hold the “Trip” and the “Reset” buttons on the dashboard for about 10 seconds. This should reset the Service 4WD Light and you should be good to go.
