You dont have to plug in a code reader to get Diagnostic Trouble Codes (DTC's) on any Plymouth Acclaim; you turn the key to run, without starting it, 5 times, then back to run. It will then flash out a code via the Check Engine Light. I.e. flash-flash PAUSE flash flash flash..END would be code 23. Google is your friend. You can find many many many webpages dedicated to this technology ~Technologic80
