I am installing a hornet 564t on a 99 tahoe. the truck had a remote start from the previous owner, so i do not know any thing about it. It has a mudule on it that says pass2 i assume this is the bypass. my questions are, does anybody have a wiring diagram for this. also when i remote start it will start then die but when i put the key in and turn to ign postion it will remote start but will not stay runningwith key in ignition in off position. I think it is a bypass issue but would like to check wiring first. also does anyone know how to reprogram unit. I only have one key. key is a factory small black key. does not look like a transponder key but could be. any help would be apprieciated need to get this wrapped up
Chev used Passlock2 for a long time. This system runs on a resistance out of the cylinder itself. There is a small yellow wire coming out of the passlock module that transmits this information to the bcm telling the vehicle a valid key turn was made. This prevents hot wiring but any key that fits will work. Multiple keys are not required for programming. I use DEI 1700G or 457G modules for those. Also the Bypasskit XK01 works or the idatalink ADS-TBSL-GM (or any of numerous other iDatalink stuff) works as well. Most other modules require a manual to know how to set a bunch of jumper switches to the right voltage. I would need an actual model number of the module to offer anything else.
PS: you could try unplugging the module,push the little button on it if there is one, plug it back in, and then start with the key. Might work, might not.
there wanst any buttons or leds or even model numbers on it so i cut it out and put a new one in and it works now thank you very much for replying. i am new at this so am trying to consume all the info possible
