Once the unit is replaced in my 2003 Suburban, any steps necessary to clear the "Service 4wd" message, or is it automatic?

If it doesn't , unplug the battery which should have been done when replacing any electronic parts should reset any service light if the problem was fixed.

I think service light will go out automatically but if you have a code you need a scanner.

On my 2004 suburban, it was automatic. I did disconnect the battery while replacing the unit though, to reset the PCM.

I recommend you contact sentry safe customer care.....contact info is on owners documentation

It is controlled by the body control module (BCM). Consequently, you have to tell the truck the system is installed.

On my suburban When I took the old assembly off, I opened the new one and put it in place with no issues. New and old were the same and I did not have to buy anything else, other than I changed my brake shoes while I had everything apart.

You would have to wipe and reprogram it to change vehicles. Basically a factory reset

No. Just remove the auto hubs and slap on the manuals. There are some "how to" videos on You tube.

You can do it yourself . You have to call them and have it activated after it is installed .Just tell them you bought the car with the alarm already in it and you added this. If you do it your self IT WILL VOID the warranty is the only thing. It is a plug and play if you have there alarm .

NO I agree with Fred buy the complete unit. In my case mine was old enough that they were not the same. Just write the color coded wire order before you remove them. Very easy to change.

I have a 2003 exactly like yours. The first time I hooked it up it upgraded the firmware to Economy mode like I wanted but then it would never recognize the truck again. The company was supposed to be re-writing and fixing my original firmware so I could return it to OEM. It's been 3 months and I still haven't heard back from them. BUYER BEWARE is all I can say. Maybe I just got a bad unit. :(

Hi, I havent had that problem - since I installed the first one a couple of years ago. But I believe that it did say it would work. I'm pretty sure it's a manual override.

Better check with the seller first because the type your Suburban takes are ATO fuses. Jeanette you can pull one out and take it to Wal-Mart and have the auto service tech match it for you....

Not sure about that one. I did it manually but see what the instructions say. Maybe you'll find something I didn't.

I think the 91 Suburban used a different system. Best to call Doc Speedo and tell him what you have. They'll take care of you if at all possible

I'm not sure. Obviously your vehicle's OBD II system monitors the PCM "powertrain control module" and or TCM " transmission control module". There should be a code stored for the trouble. I would think you will be able to clear the code, but take care doing so. Depending on the type monitor in the vehicle, erasing trouble codes may also erase the "freeze frame" data and manufacture enhanced data. You may also get a "not ready or not complete status" message. You would need to go drive the vehicle for a while to reset those monitors. Have the vehicle checked first before a technician to be safe. Hope this helps. I'm not sure.

Do you loose any functionality with this always bypassing the parking brake? I had an older headunit that when you bypassed the system it wouldn't use the GPS for navigation.
