Security light went on 18 months ago. Diagnostics reveal a bad VATS module. Replaced it with a new dealer part and purchased another one for backup. After completion, the Security was on but started and ran fine. Further diagnostics led to a VATS module, put in my backup new one, same problem. With VATS module unplugged, light is out. Using the 18 month old failed one, no light, no crank which I knew would be the result..
Checked fuses, unplugged VATS fuse, light out with no crank condition. With gauges fuse out, no light, starts fine. With C228 unplugged at bottom of steering column, light on still cranks and starts which it shouldn't. I have the shop manual, Mitchell On Demand, ALL Data for information.
Any suggestions?
