Sounds like the RCDLR is bad. IE the Passenger Door Switch.

 

You can find them pretty cheap on ebay just make sure if you have TPMS you get the correct PDM RCDLR

 

PDM US RFA = Non TPMS

PDM US RFA TPM = TPMS

 

Will this post is an education in itself, thank you for posting. I will have to research some of the terms you quoted but thats ok.

 

My one fob has been inop for many years. Elderly family member tried to replace battery and the case is in pretty poor shape, so $25.00 and two replacements has that fixed.

 

I will look into switch today or tomorrow, thanks again

Didn't even know the 03 Silverado had TPMS. Thought it only started in 05 and became law in 08. Also thought the RCDLR was part of the BCM in 03, I'm confused.

You can add TPMS to the older trucks with the addition of the Correct PDM and programming. I have even removed TPMS from both the new and old body style trucks but for legal reasons I would never tell anyone how since its a safety and federally mandated after 07. To many people that want to sue for anything now days.

 

I only glanced at the thread and did not really look at what year he had. After posting I saw something in the tail end of one of the post that might be his fob being bad. I hope the new ones he ordered work.

 

As for keyless entry

 

03 up is not in the BCM its all in the PDM.

I guess I should add that when you have power door locks with key less that it does have its own calibration in the bcm. I flash BCMs off the car for plug and play and thats one of the required answered questions in sps before you can program.

If I enter the acronym PDM in the GM server search line for 2003 Silverado the only response I get is Pump driver module for a diesel truck. I'm trying to educate myself here so hang in there. Where physically is this PDM you're talking about located?

Its in the Passenger door lock module.

Here is all data from a 2003 silv.

New fobs should be here Monday at the latest, amazon says Sunday via USPS......doubt that.

 

So the pic is the PDM or RCDLR or whatever it is called in the passenger door? And, needs to be programmed not plug and play if I understand correct?

 

I sure am hoping new fobs cure the issue, lowest cost fix so far plus mine nearly 15 years old anyway and one has nor worked for years.

 

thanks for posting

The PDM Is the RCDLR.

 

As for programming GM SPS does have programming for the PDM what functionality it actually gIves I have no idea. A new one may need to be programmed but I've never had a new one in my hand. I have programed used PDM's on the bench to the correct Vin the truck it was going to be replaced in but noticed no difference in my testing from donor truck to flashed vin in the PDM.

Coby7 & SPartanAUtoworx:

 

We are back in business. New fobs programmed smooth and are functioning. The retailer via Amazon sent his business card and recommended I go to their www site for programming instructions. I had Coby's instructions but thought I better check their site. Only difference is they mentioned I might have to hold the Unlock and Lock buttons for as long as 30 minutes. Not even close, less 30 seconds. Both are programmed.

 

Now off to mend the instrument cluster once material arrives.

 

Thanks for all the posts and advice, I have learned allot from both of you and your assistance has been a HUGE help.

 

SpartanAUtoworx, Appears you may have some used parts and I see you are showing ST Louis area. That being the case you are a stone throw away from me and I will retain your posts if that is correct.

Your welcome! I believe SpartanAUtoworx also repairs clusters if you get into trouble....

Yes, I seen he has a keen interest in many truck areas. I will keep him in mind since he is not too far from me.

 

Your little video really pulled all together. A faulty fob will trigger some test equipment, but at the end of the day its a dud. Hence, the test light at the retailer reading ok when it was not :-)

 

Now to resurrect my other thread on the cluster once I remove it. Many, many moons ago I use to do some of that work on radios, but I need to refresh the technique.

 

Thanks again

Yes, surface mount is a technique alright compared to through hole.

    • There's some truth to the above, but also, she's selling fullsize trucks and bread/butter CUV's like hotcakes, meanwhile, extracting GM's pickups from the deep discounting sales game.   GM's stock has held its own during her tenure, and the more recent buybacks are delivering cash back to investors and signal confidence in their direction forward. Even with the EV losses.   GM is an example of a modern publicly traded company. The #1 goal of any publicly traded company is to deliver the most value possible to shareholders. Despite being a car company, building the best car isn't GM's path to delivering maximum shareholder value.   McDonalds doesn't make the best burger, or the best coffee.   I've mentioned in another thread, I really don't / won't ever understand Cadillac or Buick in a modern context. Both brands are completely dead to me. I'll cede that the Escalade is a nice SUV, but the brand and nameplate mean nothing to me, and GM will never persuade me to pay north of $170k for a gussied-up Tahoe or Burb. Other people don't mind doing that and that's their purview.   The C8 shares absolutely nothing in common with any other current Chevrolet or Corvette on the market. Since its introduction 8 years ago, it's developed quite the following. It did what other Corvettes couldn't do: reduce the average age of its buyer. GM has something there, and I see them investing in the car. They'd better not mess that up.   We've successfully derailed Grumpy's thread again, but I think this one is meant to be more of a random thought thread so a little wandering is probably OK.
    • Sliding doors ftw   Also, Sienna ftw as well.  The in-laws got a 2024-2025 recently when their 2019 sienna was totaled due to a deer back in June.  They've been getting 38-40mpg on the 65mph highway they live on.
    • Forgot to mention that this started after changing the oil I use mobile 1 full syn with mobile one filter but I did add pro lube additive and was the first time doing so and is making me wonder just can't see why that would matter
    • I apologize for long post put going to try to explain everything. Parts replaced so far: Cam sensor Crank sensor Cam phaser valve Cam phaser solenoid Fuel pump Maf 1 injector Pcm Pdm   So about 2 weeks ago coming off the highway my 2007 yukon xl with the 6.2 stalled and would restart. Had unit towed back to house and I messed around with relays and unit started. Drove it the next day and same thing. Had it towed again. Scanned unit and had code p0300 with misfire data showing mainly cylinder 7 but I know that won't cause a no start. Measure fuel pressure and found only 42 psi replaced pump to have unit stall again and not restart. This time I stayed on back roads and just waited for it to restart about 30 to 60 min. During this time I found I have no injector pulse but have good power at injectors. Started unplugging 1 injector at a time and found when unplugging cylinder 7 pulse came back so i changed injecto and same issue. Turns out unit just happen to ready to start at that time. Scanned into unit and found no reason for the pcm to take away injector pulse so I replaced the pcm and same issue. I figured timing sesnor controlled the injector pulse so I replaced both sensors and while I had the water pump of i replaced the vvt components while i was in there. Read multiple people have luck chaging the maf for this issue so I changed it. Unit still stalls to this day and loses injector pulse on the ground side when it does. Have noticed watching the live data the pcm is request injectors to fire via injector pwm value. I have redone the ground wires at the left bottom of the block knowing this was the ground location for the pcm but still no luck. I am a mechanic by trade but this is having me pull my hair out. If anyone has something to have me check I will gladly im not much of a parts thrower but im about to load the cannon
    • Actually.  Wait.   I just re-read your original post.  Are you talking from INSIDE the truck you have to hit unlock?  Or from the key fob?  I had assumed from the key fob.   IF you are talking the inside unlock button, I assume you are shifting to park and its not unlocking the doors?  If so, that is changed via the settings page in the radio.  Go to SETTINGS, then VEHICLE and then it should be under LOCKS or DOOR LOCKS or something like that.
