If you tackle a dash harness swap that involves Skim and you decided to not mount the skim normally you need to place the key as shown below to avoid any issues with the Skim and getting the P1685 code.
Ok I got One I mistaking grabbed a PCM from 2003 300 to replace the damaged one that is in my 98 ES and installed not knowing anything about the Sentery key being used 2000 and the spit the 1684 or the 1685 and know wonn't start and had someone come to change the VIN# on the PCM and they can't cause the SKIM isn't showing the key being enganged any suggestions?
Wouldnt it be easier to just remove the sentry module thing (SKIM) completely ? (Sentry is useless anyway)
Cut a few keys without transponder...
Or is this some major surgery into electromechanics of the car ?
