If the tyre-pressure warning has come on in your RAM 1500 (DS, 2011–2019) after you’ve adjusted the pressures or changed a wheel, the system relearns by driving — there’s no button to press. Here’s how it works.
When It Relearns
- After checking or adjusting the tyre pressures.
- After changing one or more wheels or tyres.
Completing the Procedure
- Park level and set all four tyres to the correct cold pressures (mind the higher loaded-payload pressures on the door placard).
- Stop the engine and wait about 20 minutes.
- Start up and drive for about 10 minutes at over 25 km/h (15 mph).
- The new pressures are stored and the warning clears.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on.
- Complete the learn drive — short trips may not be enough.
- After fitting new sensors, they may need registering with a tool.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
Frequently Asked Questions
How do I reset the tyre pressure light on a RAM 1500?
Set all four pressures correctly, wait 20 minutes with the engine off, then drive about 10 minutes above 25 km/h.
Is there a reset button?
No — the system relearns automatically as you drive.
Do I need a tool?
Not for a normal relearn; a tool is only needed when new pressure sensors are fitted.
Why does my pressure warning change with load?
The 1500 specifies higher pressures for heavy payloads — set to the figure that matches your load.
If the warning came on with other lights, decode the code on autodtcs.com.
