Tech II programs remote control door lock receiver (RCDLR)

Purpose: I need to replace the remote control door lock receiver (RCDLR) on my European C6.


Tool: I have a Tech2 scan tool



According to the “GM Service Manual” it says: “Connect a scan tool to the vehicle using the pass-thru This method requires connecting the scan tool to the vehicle, Then connecting the Techline Terminals RS-232 cable to the scan tool.. ”


Tech II is connected to a computer using TIS2000 software, hence the needed dongle cable from the Tech II scanner to the computer running TIS2000 (connected in on a RS232 port).

This allows you to download the needed programming from GM directly for the RCDLR in the first place via/to the computer running TIS2000, then push it through the tech II to program the RCDLR through the OBD II port once the RCDLR is mounted in the car.

Note: some have had luck with a USB dongle, instead of RS232 Tech II dongle cable, but don’t bank that you will have the same luck and best to have a computer that has a RS-232 port to run TIS2000 on.



Important: Prior to programming per the information below, the Radio and HVAC Fuses MUST be removed and the ignition must be in “Key On Engine Off Mode” The radio and HVAC fuses can be located in the BCM fuse block on the passengers floor electrical center. One of the fuses is labeled RDO/S’BAND/VICS and the other is labeled HVAC/PWR SND.


Program the RCDLR with revised software using TIS-2-WEB “Pass Through” method. When programming, it is required to select “Replace and Reprogram ECU”.


Important: If the programming procedure does not finish successfully and the RCDLR appears to be in a “locked up” state do not turn off the ignition, follow the directions below…


The RCDLR can be reset by removing the RCDLR fuse (#11 in the UBEC) for at least 30 seconds or longer and then reinstalling it. Once this fuse is reinstalled in the UBEC, there will be a 2 minute window to restart the programming of the RCDLR through TIS2WEB. Failure to restart the programming of the RCDLR through TIS2WEB within 2 minutes may cause programming to fail and this procedure will need to be repeated. It is recommended that the Tech 2 remain connected to the vehicle and that the TIS2WEB application is open and ready to program the vehicle prior to reinstalling RCDLR fuse #11 into the UBEC.



This video will walk you through both stand alone, and pass through programming (go to 8:30 for pass through and note that the op is using a tis2web disc to access the needed programming, instead of pulling it down over the web).



And again, As for the latest RCDLR updates, tis2web is needed for that to pull the needed program; unless you can get your hands on a tis-2-web legacy disc current enough for your car and there are not any updates from that point forward from the disc.




How to raise and lower idle rmp using a Tech II scanner

Confirmed! Tech II scanner is able to raise and lower the idle!


It’s possible for GM vehicles to get the ecm reprogrammed for the fast idle increase. your local dealer should be able to help you out. here is how it works.



Programming ECM For PTO Idle Up Operation



2001-2007 Chevrolet Silverado Classic

2003-2009 Chevrolet Kodiak

2001-2007 GMC Sierra Classic

2003-2009 GMC TopKick

with 6.6L or 8.1L Engine




Connect the Tech 2 and follow the steps below to program the ECM for idle up feature with PTO operation:


Turn on tech 2 and build the vehicle


select “Powertrain” (Or “Vehicle Control Systems” on later models)


select “Special Functions” (or “Module Setup” on later models)


select “PTO Options”


select “Change Options” (soft key at bottom of the screen)


select F1 “PTO Preset Speed Control”


select pto max engine speed set to 2200 – 4400 rpm (not below 2200)



Note: These steps will not allow the engine rpm to exceed the rpm setting, even during normal driving if the PTO switch is on


select stand by speed (base fast idle ) set to 1200 (this setting is initial fast idle)


select PTO set speed – set to 1400 rpm


select PTO resume speed – set 1700 rpm


select PTO max engage speed – set to 1800 rpm (PTO engagement inhibit speed)


select PTO engine shutdown – no


select PTO engage relay – no


select PTO feed back -no


select “Reprogram” (soft key at bottom of screen) “Waiting For Data” displays on screen-once data comes back verify settings remain


key off- until tech 2 “beeps” and screen shows “no communication” (Very important step if missed setting will not store)


key on – verify settings remain on list


operate pto

Excellent tool so far. no bricks or problems.
extremely fast for cas1, 2 & 3
for cas3+ if need downgrade 10 minutes and seems safe, ISN read from DME 10 minutes does not support all DME is down side.
make sure you have proper power on the car
cas4 /+ did not check

cas4 F10 – ok (new key)
cas4+ F10 – ok (new key) isn from org key or dump DME
fem/bdc F31 – ok – reset mileage, change isn, change vin, make keys with oryginal key and with dump from DDE
cas3+ E60- ok , downgrade and make key with isn from org key

08-Mini Cooper – Added Key With CGDI Bmw programmer 
the wording was alittle confusing when it ask u is it a prox or non prox this car was a non prox so u push yes and for add keys u put your first key in the programmer slot then put your unlocked key in and then your done just make sure u have jumpers Hooked up so u don
t lose power and I had a surge protector on my obd to stabilize the power cas3+

So I purchased the cgdi programmer.

I figured out how make key for cas2-3 but I cant figure out how to use this programer for cas4. I tried looking online but only find for cas3,no instructions for cas4, can anyone tell me steps for cas4 I have f10 I can try one.

Cas4 can only be done by reading DFlash from Freescale cpu then load into programmer software and generade key. It can no ne done by obd.
Need xprog or vvdi prog to read the dflash.
