silverado Service Tire Monitor System Message on 2008 Duramax

[jgr54]

Having difficulty isolating problem on my 2008 Silverado LT Crew Cab (Duramax). Months ago while traveling, the TPMS light began blinking and "Service Tire Monitor System" was displayed on the DIC.  This happened numerous times intermittently (over several days). When I would look at tire pressure on the DIC, it would indicate 1 lb for one or more of the tires...... never the same tire each time.  Initially the problem would last for a couple of minutes and then clear by itself,.  Over time, the problem persisted until finally the Service Tire Monitor System displayed constantly.  The TPMS light blinks for a few minutes after starting vehicle, then stays lit constantly while vehicle is running.   The DIC now shows "--" instead of any numbers for tire pressure for every tire.  Based on the fact that all of the sensors are less than 2 years old and the problem initially showed 1 lb for different tires, I do not believe it is a tire sensor problem. (I could be mistaken).  I replaced all 4 sensors -- two of them about 20 months ago and the other two 6 months ago.  When the original sensor on one tire became weak, the DIC indicated low pressure on just that tire, not intermittently on all tires.  The symptoms now are different than when the battery was dying on an individual tire.  

 

My understanding is that the Remote Control Door Lock Receiver (RCDLR) serves as the receiver for the door Remote and the TPMS sensors.  So far, I have removed the DSM fuse (which powers the RCDLR) for about a minute and replaced it..... just on the outside chance removing power to the RCDLR would resolve the issue. It didn't.  My gut feel would be that the RDLR is defective, but all comments related to the RCDLR being the issue also indicates the door Remotes quit working.  My Remotes still lock/unlock the door just fine.  

 

Any suggestions on what to check or do next would be greatly appreciated.  THANKS!!

batteries in the sensors in the wheels have gone out.  Need to have new sensors installed, should solve the issue.

This.

If it is intermittent that means that they are going dead. Unfortunately normally when one of them goes, the others aren’t far behind. You may get lucky and get away with replacing one. But I would replace them all at the same time. You can get them pretty cheap off eBay. I know the dealer wants a fortune for them.

Just for future reference. If the light comes on and it is solid with no blinking at all. That indicates that you have a low tire. And a message should pop up saying check tire pressure. If it is blinking and saying service tire system, that means that there is a fault 9/10 times with 1 Of the tire sensors or possibly multiple sensors.

Do the relearn procedure for the Tpms sensors and see if that clears your problem. Maybe they need to be reprogrammed

Over the last couple of winters my two rear tires would show low. I know that the inflation was correct. Between the two winters, I had the tires replaced. I think the tire guy put the same wheels back, in the same locations, with the new tires. I just thought the sensors were adverse to cold temps. The light went out in the spring.

 

The other day I had the tire shop rotate tires. We had a warm spell, and the temperature was about 45 degrees that day. Since, the weather has gotten cold again. Surprisingly, the light did not come on. I don’t know if the super cold made the sensors reprogram themselves. I didn’t have any charge for new sensors, and the rotation was complementary.
