can any one give my advice on how to by-pass this system. Mine has gone hay
wire, sometime start and run other start and stop. The dealer want WAY to
much to diagonose and repair, isn't their a way to by this?
pull the clamshell from the steering column. find the VERY thin black and
yellow wires that run together from the key cylinder. Measure the
resistance (with the truck running) between the yellow and black wires. In
some cases, you need to measure the "key side" of the yellow wire (cut
it)...Test multimple times, starting and stopping the truck each time. The
resistance should be a very steady reading. Find a resistor that is within
3% of the value you measured. Run that resistor inline with the black wire,
and you've effectively defeated the Passlock II system permanently.
In your case, you're doing it to allow the truck to run...many cheesy
installers do this to allow remote starting, inadvertently bypassing the
security system altogether (not cool)
