Once you turn it off in the PCM you can Huck the passlock module. The PCM no longer seeks a signal from it.
Good to know. The tuner cautioned me the security light may still blink at key on so I pulled the bulb from the cluster.

I was told that about the bulb too. Had the PL tuned out last fall, and it'll be on sometimes. Then goes off for a while, but as long as the truck starts, the light doesn't bother me!
Pinger, I think that a remote switch is a good idea for your truck. Probably a good idea for any truck on propane, since as you pointed out that the fuel pump doesn't need to be on when no petrol is needed to run the engine.
HiHello,
I'm hoping someone may be able to help me on what I think is a passlock issue...
I go to start the truck, and it will start and run for a second or two.. then shutoff... passlock light flashes when the truck shuts off.
Now, I tried to do the 10/30 minute passlock relearn procedure.. Heres what I do.
- I attempt to start
- then leave in the on position for ten minuets
-The instructions say the security light should stay on.
The problem I have is the light will not stay on, so I cannot seem to get it in relearn mode. When I attempt to start, the security light will come on and flash for a few seconds, and then goes off.
Any help would really be appreciated. This truck is super frustrating.
The ONLY WAY to get rid of the Passlock system is to have it electronically deleted from the PCM. The relearn procedures work, a couple of times and then don't work anymore. The resistor install works, until the resistor changes resistance after a while. And with it you have to hack up your ignition wiring....Hi
I know th is an old thread but how did you fix your truck? Mine is like yours where the security light doesn't stay on during the relearn. Did you go with the suggested by pass route? Thanks
I ran into this just the other week. Ended up having to replace the ignition switch in the column and the passlock module because the passlock module fried and the ignition module went bad as well. Better yet, the stupid ignition module on the block went bad at the same time. Ended up finding a white the nice got into.Hello,
