I have a 1999 Dakota Sport with a 3.9L engine and the check engine light is on. How can i get the error codes? The ON-OFF-ON-OFF-ON method doesnt work on my truck. Thanks in advance. Chris.

Unfortunately, for that model year, there isn't any way to retrieve the diagnostic codes except with an OBD-II scan tool.
That's a check of the instrument panel cluster - the gauges, lights, LCD segments, etc. It's just a visual check that you can use to determine if you have a bad gauge, or if a lamp is burned out. No diagnostic codes are available from that.
